21ee1c0200 SkSL: Remove all $gsamplerFoo types
These are GLSL-isms that weren't really implemented - each one was a
"generic" type that only resolved to a single underlying type. We've
got along just fine without them for years, so update our sample()
declarations to take the actual underlying type. (Note that we had
worked around this by declaring an integer version of sample where
necessary, so we can presumably keep doing that in the future).

33c64a4473 SkSL: Remove "null" as a type and literal value.
Nullable fragment processors still exist, but they're handled
transparently by sample() within C++, so there's no need for .fp files
to ever do these tests manually.

cd228e25c7 SkSL: Remove $gvec and $gfloatN types
These were unused, and I don't think they were correctly defined, given
the inconsistency in naming and construction. If we do end up needing
something like this (a variant type for returns from sample(), we can
re-add them correctly).

c5ff48648a Elide return expression temp-var in vardecl-less blocks.
Previously, a return statement inside a scoped Block would always result
in the return expression being assigned to a temporary variable instead
of replacing the function-call-expression directly. This was done
because there might be variables inside the Block; these would have
fallen out of scope when the expression is migrated to the call site,
resulting in an invalid expression.

We aren't actually examining the return expression so we don't know if
it uses variables from an inner scope at all. (Inspecting the return
expression for variable usage is certainly possible! But it's a fair
amount of code and complexity for a small payoff.)

However, we can very easily get most of the benefit here without paying
for the complexity. In this CL we now look for variable declarations
inside of scoped Blocks. If the code doesn't add any vardecls into
scoped Blocks, there's no risk of scope problems, and we don't need to
use a temp-var to store our return expressions. If any vardecls are
added, we go back to using a temp-var as before.

e42716032b SkAnimatedImage: Always respect exif orientation
No known clients (CanvasKit, Android) want to ignore the exif
orientation in an animation.

A follow-on CL will deprecate SkAndroidCodec::ExifOrientation, leaving
it up to the client (e.g. SkAnimatedImage, hwui/ImageDecoder) to
handle the orientation. Add SkEncodedOriginSwapsWidthHeight to assist
clients to do so.

Update stoplight_animated_image GM. It previously showed using
SkAnimatedImage without respecting the orientation, which is no longer
supported. The new version replaces the left half of the image with the
right.

Remove assert that is no longer true. Originally, an SkAnimatedImage was
"simple" if it did not have a crop or postProcessor. This is no longer
true if has an exif orientation. Add a test that calls the simple
constructor and verifies it does not crash.

b6a382975a Report aa bloat in triangulating path renderer
Ops should report HasAABloat::kYes if they use coverage AA approaches.
This was confusing the new GrClipStack into thinking a subpixel path
(that should have been coverage) was non-AA, and in certain transforms
this would then not touch pixel centers and the clip stack would reject
the draw early.

6ed863a30a Rewrite faceforward/refract to work around Adreno driver bug.
Rather than return a complex ternary expression, we now assign the
complex expression into a variable and then return that variable.

This works around a bug in the Adreno driver where it fails to parse
"(complex-expression).swizzle" and errors out with "Cannot offset into
the vector." Instead, we now store the complex expression into a
variable and return that variable. This changes the final assembled
code into a two-parter, "float2 v = (complex-expression);" followed by
"v.swizzle". This is easier for the Adreno driver to swallow and works
around the error seamlessly.

Example Adreno failure: http://screen/Bkx5zRvaMEbuCTh

74ebd7e6ce Add support for inlining switches with returns inside.
Because we use `continue` for flow control handling now, we can escape
from the middle of a switch statement. This wasn't possible when we used
`break`.

This unlocks some pretty stellar optimization opportunities if the
switch value can be determined at compile time; see BlendEnum for an
example.

77702f1704 Eliminate inliner temporary variables for top-level-exit functions.
When we determine that a function only contains a single return
statement and it is at the top level (i.e. not inside any scopes),
there is no need to create a temporary variable and store the
result expression into a variable. Instead, we can directly replace
the function-call expression with the return-statement's expression.

Unlike my previous solution, this does not require variable
declarations to be rewritten. The no-scopes limitation makes it
slightly less effective in theory, but in practice we still get
almost all of the benefit. The no-scope limitation bites us on
structures like

@if (true) {
    return x;
} else {
    return y;
}

Which will optimize away the if, but leave the scope:

{
    return x;
}

However, this is not a big deal; the biggest wins are single-line
helper functions like `guarded_divide` and `unpremul` which retain
the full benefit.

If we aren't wrapping the inlined function body in a loop, there's no
need to add a scopeless Block; we've already got one. This doesn't
affect the final output meaningfully--it just suppresses a newline--but
it's one fewer IRNode allocation.

0a442b71b0 New SkSL code generator that emits directly to skvm
Still TODO:
- Function calls. Can do these by inlining everything (recursively).
- Additional flow control: ES2 for loops can be supported (via
  unrolling), and switch() can be implemented. (Was never done in
  ByteCode).
- Uniforms and params have been set up to work very generically (caller
  just supplies IDs, the generator collates everything into a master
  working list). Builtins should work the same way (caller supplies a
  map of builtin ID -> skvm::Val[]?), so that we don't need a special
  case for device coord.
- Figure out integer type policy. Today, it's a mix of only supporting
  signed integers, and just treating all integers as signed, even if
  they're not.
- Now that defining intrinsics is *much* simpler, stop defining so many
  of them in sksl_public.sksl, and just implement them here.

- For-loop increment expressions. These are sometimes required due to

6f31e27f1e Improve inliner variable name mangling.
Previously, multiple inliner passes in a row would each apply a
separate name mangling to variable names, so names like "_25_14_3_1_pos"
were not uncommon. This change demangles the name before re-mangling it,
so we would have just "_25_pos" instead.

It's not important, but it makes things easier to read.

9b0fc9c9c1 sketch Half in skvm
Key design points...

   A) Take care to not commit too much to Half's range or precision.
      In particular, don't offer operations whose result might not
      be representable in Half.  E.g., shy away from Half divide,
      not just because we might not be able to do a native divide,
      but even more so because division produces results that might
      not fit in Half, ±inf or NaN.

   B) No native Half loads, stores, uniforms or splats,
      instead converting from I32 or F32.  This keeps the entire
      front-end (user code, Builder, etc.) specified in terms of precise
      format and oblivious to the various backends' representations of
      Half.  Native Half splats would be less trouble than uniforms I
      think, and uniforms less trouble than loads and stores, but still
      enough a pain that we're better of deferring any of that for now.
      (Explicit fp16 uniforms do make sense to me though.)

   C) Keep the current F32-based Color and all the effect virtuals
      that use it around, introducing parallel Half-based HalfColors
      and entry points for those.  The key cool idea here is to have
      the default entry points for F32/Color and Half/HalfColor call
      each other, so that any given effect can implement one, the other,
      or both and always be compatble with however it's called.
      This is mostly about incremental rollout, but I suspect we'll
      have areas that stick to F32 forever.  (Think the IEEE 754 32-bit
      float specific bit hacks we used for approx_log/approx_exp.)

   D) (not done yet) allow implicit Half->F32 conversion, but not
      the other way around of course.  This makes it easier to lean
      on the body of F32 routines we already have, and again mostly
      helps enable incremental rollout.

977715763d Have SkWuffsCodec use one Wuffs decoder
This mostly undoes commit 2777cd37 "Have SkWuffsCodec use two Wuffs
decoders", also known as
https://skia-review.googlesource.com/c/skia/+/250937

Using two Wuffs decoders is more complicated, but was necessary to allow
getFrameCount() to update when part-way through an incremental decode
while more data comes in. Updating that count matches an existing
Chromium test (TestResumePartialDecodeAfterClearFrameBufferCache).

On further discussion (crbug.com/1132828), that behavior is unnecessary
(and that Chromium test will be removed), so having Skia use two Wuffs
decoders is unnecessary complexity.

Removing the now-redundant WhichDecoder enum (an enum with only one
possible value), a mechanical change, will be a follow-up commit.

887ac49f9e Always use AutoLayerForImageFilter
This definitely simplifies the drawing code, but always copies the input
SkPaint so that it can be modified if necessary. If we get perf hits, we
can just revert this. We could keep it using a copy-on-write, but with
this change, I believe we've removed the majority of instances of
SkCopyOnWrite<SkPaint> inside SkCanvas. There's just one LatticePaint
struct that's overly complex for what it does that I can clean up next.

A middle ground would be to keep the copy-on-write behavior, but drop
the branch on image-filter. Given the lack of perf needle movement on
some of the other simplifications that avoided technically unnecessary
paint copies, I doubt it's worth the complexity.

As part of this change, since the draw calls no longer branch based on
the presence of an image filter, the AutoLayerForImageFilter takes over
calling predrawNotify() in its various forms. We don't have to follow
through with that, if we'd rather have the notification be called out
explicitly within the draw call itself. I've found it easy to forget to
call predrawNotify(), or keep it in the right place while updating draws
so I may be biased.

1f0dc9cd1b Update SkSL type priorities to differentiate signed/unsigned types.
Previously, coercion between a signed type and an unsigned type was
treated as "no cost" because these types shared the exact same priority.
This meant that we couldn't choose the proper overload with function
calls that only differed in signed-ness, like:

  void fn(int4 x);
  void fn(uint4 x);

So we would always choose the int4 version since we encountered it
first. Now, we can choose the correct overload; signed types now have
a slightly elevated priority over unsigned types, allowing coercion
costs to work normally.

Also added some comments to `determineFinalTypes` while trying to see
if that needed some improvements as well, but this turned out to be
a red herring--it didn't need any functional changes.

5d8f55bfa8 Update last gm to use sampling, hide legacy api
persp_shaders_ gm expected diff (in gpu backends only), due to change
from filterquality (which gpu and cpu interpreted differently for mips)
to samplingoptions (which both backends interpret the same).

Specifically for kMedium:
- gpu treated as SkMipmapMode::kLinear
- cpu treated as SkMipmapMode::kNearest

This ensures that if the original src had transparent-black in the
border pixels that our downsampled image does as well. Otherwise,
clamp mode causes these nonzero border pixels to produce vertical

1fd8ac87dd Add gr_cb class to help tracking command buffer uses of GrGpuResources.
Essentially GrGpuResources have two counts now. The original fRefCnt has
not changed and is still used for things like knowing if we can reuse
a scratch texture. The new fCommandBufferUsageCnt is used to track
when a resource is in use on a command buffer or gpu in general. We now
delay calling notifyRefCntIsZero until both of the counts are zero.

d06d4a983f Fix matrixCompMult halfNxM implementation and add unit tests.
The existing code didn't work properly with half types since the $mat
type encompassed both halfNxM and floatNxM. This was fixed by splitting
the half types out of $mat into a separate $matH generic.

Unit tests now compile properly for GLSL, but generate errors in SPIR-V
and generate Metal code which attempts to call a non-existent intrinsic.

31dd1f8de8 Remove SkDrawIter entirely
SkDrawIter goes away, as well as the DRAW_BEGIN, DRAW_END, and
FOR_EACH_TOP_DEVICE macros. A new macro TOP_DEVICE is added that
simplifies checking for a null device (which is currently only possible
if SkCanvas::init() was called with null). The intent is that this will
be replaced with just "this->getTopDevice()->" in the future.

The rest of the auto-layer magic that happened in DRAW_BEGIN is now
explicitly written out in the draw functions. Additionally, it has
been updated to check for an image filter. When there's no image
filter, it completely bypasses the construction of the AutoLayer object.

This extra check maybe isn't worth the code complexity, but some draw
methods had previously followed this pattern, so presumably stack
allocating the AutoLayer had some overhead in tight draw loops.

Initially we restricted tessellated stroking to opaque solid colors.
This CL adds support for transparency by enabling a stencil test. The
stencil test also allows us to use mixed samples.

23cbb99c8e Fix blending bug in animated webp decodes
Bug: webp:490

Depending on the encoded image, SkWebpCodec may need to blend the
the output from libwebp with the prior frame. It does so using the
method blend_line, which expects the libwebp output to be unpremul.

Prior to this commit, SkWebpCodec sometimes told libwebp to premultiply,
and then passed that premultiplied data to blend_line, which
premultiplied again.

Use webpInfo's alphaType to decide whether to premultiply. Consolidate
choosing its alphaType into one block. The functional difference is that
if (blendWithPrevFrame), we no longer premul if the dst is kPremul.

Move declaration of webDst to where it's used.

Add a test.

06b84efcb3 Improve Metal support for out parameters.
We now insert helper functions which defer the assignment of out-
parameters back into their original variables to the end of the
function call. This allows us to match the semantics listed the GLSL
spec in section 6.1.1:

"All arguments are evaluated at call time, exactly once, in order, from
left to right. [...] Evaluation of an out parameter results in an
l-value that is used to copy out a value when the function returns.
Evaluation of an inout parameter results in both a value and an l-value;
the value is copied to the formal parameter at call time and the lvalue
is used to copy out a value when the function returns."

This technique also allows us to support swizzled out-parameters in
Metal, by reading the swizzle into a temp variable, calling the original
function, and then re-assigning the result back into the original
swizzle expression.

At present, we don't deduplicate these helper functions, so in theory
there could be a fair amount of redundant code generated if a function
with out parameters is called many times in a row. The cost of properly
deduplicating them is probably larger than the benefit in the 99% case.

8685c31dd1 Apply clip in device space for onDrawBehind().
The back image for saveBehind was in the device's space, but clipping
when drawing to that same region used clipRegion(), which is affected
by the global-to-device matrix. This change switches to using clipRect()
and a temporary whack of the local-to-device matrix to identity so that
we can exactly specify the same rectangle in the device space.

This is important once image filters start changing the global-to-device
matrix to no longer be integer-translations.

b21fac2481 Detect cases in Metal where out params are swizzled.
We will need to emit a helper function to work around this case, as
GLSL supports swizzled out params, but Metal does not. In this CL, we
do not yet synthesize the helper function, but we annotate the code with
a comment indicating affected calls. (Of course, this will be replaced
with a helper function in a followup CL)

Even detecting a swizzle is actually an interesting problem, because
index expressions are sometimes actually swizzles, depending on the type
of the base expression. Also, the index or swizzle might be nested in
several other valid assignable expressions.

2. The canvas state helper functions are updated to work with DLLs
   (confirmed tests pass on Windows in cross library mode)
3. The tests now always run, and the cross-state define only changes
   what version of the helper functions are used
4. Updated the dlopen code in the test to use the SkOSLibrary ports
   instead of calling dlopen/dlclose directly.
5. Fix bugs in SkCanvasStateUtils that were uncovered as part of
   always running these tests.
6. Switches the define away from SK_SUPPORT_LEGACY_CLIPTOLAYERFLAG
   to SK_TEST_CANVAS_STATE_CROSS_LIBRARY, since these tests are not
   strictly speaking testing the unclipped layer feature.

f2bd501ce3 Use references instead of pointers for Metal out params.
Pointers require decorating the variable with a * to read back the
value, which the code generator did not properly handle. There was a
special case to add the * but it only supported assignment into the
variable, not reading back. References require no special decoration.

This change fixes compile errors in Functions.sksl with the "bar"
function. (This test marks `x` as an inout but never actually mutates
it.) It also allows us to remove a special-case workaround for `frexp`,
an intrinsic function which uses a reference for its out-parameter.

Additionally, this CL adds a non-inlining copy of "OutParams.sksl" to
the Metal test directory, as most of our tests which use out-parameters
end up inlining all the code, which hides these sorts of bugs.

2630ea3312 Disallow identifier names that overlap existing types.
It's not legal to use identifiers like "int" or "sampler" to name your
variables (or enums, or structs, etc.). SkSL will now report this as an
error instead of relying on the driver to catch this.

(Note that in some contexts, it might be legal by the spec to reuse a
name that you introduced yourself, depending on the scope. In practice,
this confuses Apple GLSL, so we shouldn't support it anyway.)

This caught several existing places in our code where we used the name
"sampler." These were never exposed to the driver (they were intrinsics
that we would replace during compilation) so they were harmless before.

There's no reason not to do this, though there are so many registers on

I let dst() take a second hint, which makes most of these super easy;
double hints don't really come up on x86 because we've got all that

The most subtle bit is that it's safe to alias the index and destination
registers of the gather ops... we pull an index out of a lane, load the
value, and shove it back into that same lane, all totally safe.

d39aec940d Remove multi-dimensional array support from the parser.
Previously, our AST structures would include a "sizeCount" for arrays,
which indicated the number of AST nodes associated with array
dimensions. Since GLSL only supports a single array dimension, this
field has been replaced with "isArray," a boolean indicating whether we
have a single AST node for array size. This allowed many array-size
based looping constructs to be replaced with simpler non-looping
equivalents.

This change flushed out a few places where the parser was not actually
enforcing its promised maximum array-dimensionality.

Also found some duplicated code in variable-declaration parsing,
related to parsing array-sizes and initializer expressions. This has
been de-duplicated by using a lambda. (This change was likely why this
CL was not net-negative for LOC, but it's simpler and cleaner.)

So replace all that with

Bug: b/160984428

Add more fields to SkCodec::FrameInfo, which describes the properties of
an individual frame in an animated image. This allows a client that
wishes to seek to determine frame dependencies so that they can decode
an arbitrary frame, which in turn will allow SkCodec to remove
SkCodec::FrameInfo::fRequiredFrame. Currently, SkCodec seeks through the
stream to determine frame dependencies, but this is unnecessary work
(and storage) for a client that does not want to seek.

These fields also support the proposed APIs in go/animated-ndk.

Move SkCodecAnimation::Blend from SkCodecAnimationPriv (and delete that
file) into SkCodecAnimation.h. Rename its values to be more clear.

Merge common code for populating SkCodec::FrameInfo.

Add a test for a GIF with offsets outside the range of the image. Note
that libwebp rejects such an image.

6bef6a7858 Fix flipped array dimensions in SkSL.
The proper approach for creating multi-dimensional array types is
complicated, so I added a function in SymbolTable which does it the
right way (addArrayDimensions). I found all the places in SkSL which
created arrays from base types and size arrays, and refactored them to
call addArrayDimensions instead of doing it manually.

I believe that this approach fixes a bunch of minor issues with multi-
dimensional array types; some are visible in the current codegen output,
and others are latent bugs. e.g. in some instances, a Variable's type()
was silently holding flipped array dimensions, but this never led to
a visible bug because we ended up using the VarDeclaration's baseType()
plus sizes() everywhere that the type was used. (In particular, this
caused debugging headaches in http://review.skia.org/340137 where I'd
use a Variable's type and suddenly its array dimensions would be wrong.)

986c7fb8ca Fix codegen errors with Metal return statements.
The Metal return type from main() diverges from the SkSL source, so we
patch it in the Metal code generator. This CL improves the patching
process in multiple ways:

- A `return` statement from a fragment processor main() is rewritten to:
    return *_out;

- A `return` statement from a vertex processor main() is rewritten to:
    return (_out->sk_Position.y = -_out->sk_Position.y, *_out);

- We avoid emitting a duplicate `return *_out;` statement if we can
  determine that main() already ends in a return statement. This is
  harmless either way so it doesn't necessarily catch everything. (e.g.
  it doesn't detect an if/else which returns at the end of both blocks.)

Also added a unit test which returns from the middle of a vertex shader,
since we didn't test this anywhere and we need to verify that
sk_Position.y will be negated. (This didn't work properly before.)

0c2cc23561 rearrange types in SkRuntimeEffect program_fn()
Our stack contains values that are either F32 or I32, and notionally
stores them as F32, using pun_to_I32() when it's actually an int.

Instead, remove that F32 bias and store the skvm::Val, the type-erased
value ID that underlies both F32 and I32.  Then reconstruct the types as
needed using pop_F32() / pop_I32(), or the now-smarter
unary/binary/ternary.  Those helpers work in terms of Val now, and will
infer the right F32/I32 types from their argument functor.  A few other
stack manipulators now also work in a type-agnostic way.

What do you think of this instead of separate F32/I32 stacks?  The cond
and mask stacks are already conceptually crowding things a bit, and this
lets us keep the primary stack all in one place.  And it'd be tricky to
index into split F32/I32 stacks for things like kLoad, kStore, kDup.

Metal previously emitted the SkSL enum typename, which is meaningless to
Metal since we do not emit the enum itself anywhere. Metal now emits
"int" for an enum-typed variable.

(GLSL already correctly emits "int" for enum types.)

21f5f450a4 Fix SPIR-V compilation error with arrays of samplers.
This CL addresses the root cause of the fuzzer issue, by checking for
LayoutIsSupported before getting the MemoryLayout of a type. However,
this array ought to be detected as an error everywhere, as samplers are
opaque types; at present, this code compiles without error in GLSL and
Metal. This is an issue for followup CLs.

GLSL's actual support for arrays of samplers is interesting and probably
too nuanced for us to try to emulate:

https://www.khronos.org/opengl/wiki/Data_Type_(GLSL)#Opaque_arrays

"Under GLSL version 3.30, Sampler arrays (the only opaque type 3.30
provides) can be declared, but they can only be accessed by compile-time
integral Constant Expressions. So you cannot loop over an array of
samplers, no matter what the array initializer, offset and comparison
expressions are.

Under GLSL 4.00 and above, array indices leading to an opaque value can
be accessed by non-compile-time constants, but these index values must
be dynamically uniform. The value of those indices must be the same
value, in the same execution order, regardless of any non-uniform
parameter values, for all shader invocations in the invocation group."

dc75a97b80 Add global struct definitions to SkSL.
Previously, GLSL and Metal code generators would emit a struct wherever
the type was first used in the code, regardless of where it was
originally defined or what scope the type needs to live in. This CL adds
a ProgramElement for struct definitions, so that structs will now appear
at the top-level as they were originally defined. In the case of Metal,
some special handling is also needed to handle the Globals struct
properly.

Not yet fully supported:
- No special handling for structs declared inside functions yet
- No support for structs in separate scopes with overlapping names
The severity of the remaining issues depends mostly on whether we want
to support structs inside functions in Runtime Effects.

712fd6bbb9 Add support for enums in Metal code generator.
Enums are an SkSL-only concept--when we output code, we emit plain
IntLiterals--so the fix is simply to ignore the Enum program element
when we encounter it. This is what GLSLCodeGen does as well.

Also added a unit test to confirm that enums work normally, and that
enums are subject to optimization and static-comparison checks just as
ints would be.

d6449e9291 Remove ^^ operator from Metal codegen.
^^ is not an operator in Metal. != can be used for the same purpose.

a35fcd6881 Don't force linear when extracting miplevel
Sorta introduced here: https://skia-review.googlesource.com/c/skia/+/338318

When we switched the controller from filter-quality to sampling, we
'continued' the old behavior of forcing bilerp when sampling a miplevel.
This matched the old enum, but the new code should respect whatever
fFilter the client has set.

39b4c86fe9 Use sampling inside legacy bitmapprocstate
Goal is to isolate where we look at the quality enum to the fewest
number of places (e.g. single place in doStages) -- to make it clearer
how we'll be able to eliminate it going forward.

8d78da910e more arm64 ops
- easy: ceil, floor, sqrt
  - index is our first arm64 instruction to need a temporary,
    but other than that is pretty simple, just N - iota as usual.

With Op::index now supported, `viewer  --slide GM_runtime_shader`
frame time drops from ~1ms to ~0.24ms.

I accidentally swapped in a float-subtract for an int-subtract and
everything worked fine.  o_O

8b16beeaf4 remove SkVM uniform8/16
Uniforms in practice are always pointers or 32-bit ints or floats, so
these are essentially dead code. The change to SkVMBlitter.cpp is the
only interesting change, and I think it makes more sense now than
before.  The program will need float coverage in the end, so might as
well feed it one directly.
