f3274e035b Add particle GMs
They've only existed as a custom slide in Viewer until now, so it was
easy to break them (and also hard for people to see a minimal set of
code to use them).

0492a744a5 Add some SkSL intrinsics to our dm tests.
This CL adds dm coverage for:
- abs(half)
- sign(half)
- floor
- ceil

And creates test output for abs(int) and sign(int); these aren't covered
by dm because they don't exist in ES2 and so are unsupported by Runtime
Effects.

da5cdf6a70 Add default uniform binding value for Metal/SPIR-V.
This allows interface blocks in Metal to compile even if
`layout(binding=...)` is not specified. It will also be used in SPIR-V
in the followup CL, when an interface block is automatically synthesized
for top-level uniforms.

This CL also reorganizes the unit tests around uniforms a bit.

ebb37e7db0 Rewrite GrPathTessellateOp as GrPathInnerTriangulateOp
Simplifies the op to always triangulate the inner fan. We ensure this
will always work by using breadcrumb triangles. Also removes the
fail-on-non-simple mode from GrInnerFanTriangulator since it isn't
being used anymore.

b7f5e1b20d Fix SkSL test compilation on Windows.
The command-line length limit on Windows is very low (~8000 characters)
so it's infeasible to pass a large number of test files directly on the
command line. Fortunately, GN includes a built-in workaround.

4d6310ab20 Support half4 return values from main() in the SPIR-V code generator.
This creates a helper function, _entrypoint, which invokes main() and
assigns its result into sk_FragColor. We also make sure to prevent
sk_FragColor from being dead-stripped from the code during IR
generation.

At present this is useful for allowing our SkSL test shaders to compile.

e24127ce05 Directly measure CoreText weight mapping.
CoreText reports weight on a [-1.0, 1.0] scale with 0 being 'regular'.
Unfortunately the mapping from the [1, 1000] scale more commonly used
is not uniform and also varies between system fonts and fonts created
from data. For system fonts the NSFontWeight values will be used if
available, but there is no corresponding API for fonts created from
data. Previously the values for fonts created from data were hardcoded,
but the values have changed again recently. Directly read these values
by varying the weight in the font data, creating a CTFontDescriptor from
this data, and then using the value reported by CoreText.

70a0d2cc4f Rewrite GrPathTessellateOp without inner fan triangulation
Adds a new op, GrPathStencilFillOp, that is a greatly simplified
rewrite of GrPathTessellateOp without inner fan triangulation. This op
is a very simple Redbook method built on tessellation. For now we
leave GrPathTessellateOp as-is. The next CL will change it to do inner
fan triangulation exclusively.

e3a91cf31c Fix fuzzer-discovered error with variable scoping.
In GLSL and SkSL, control statements don't require explicit braces
around single-statement children. That is, the `match = true` child
statement here doesn't need to be braced.

    if (condition) match = true;

Because there are no braces, we never create a Block or a dedicated
SymbolTable here.  This is normally not a problem, but the fuzzer
discovered that it can dump things into the symbol table inside a child
statement:

    if (condition) int newSymbol;

This becomes problematic because the symbol name now outlives its block.
This means `newSymbol` can be referred to later, which should be illegal
(and can cause the optimizer to blow up since the structure is bogus).

There doesn't seem to be any reason to allow this code to compile; the
user can add an explicit scope here to make it reasonable, and it's
(almost) meaningless to declare a symbol that's instantly going to fall
out of scope. This code is now rejected with an error message.

2a4c0fbdca Improve memory layout handling in SPIRV generator
Added asserts that verify we don't try to emit the same struct or array
with two different memory layout rules. Some code paths were failing to
inspect the associated variable, leading to incorrect errors about the
attached offsets of members.

Added a test case that triggered that error, and also triggers the new
asserts.

Then, fixed the underlying cause: writing out the struct definition as a
side effect of accessing a member in getLValue().

4f2bcff08e Implement Type cloning for enums and structs.
As far as I know, there shouldn't be a way to introduce a struct or enum
other than at global scope; the keywords are not accepted inside a
function body. In fact, I wasn't able to find a way to exercise these
code paths in practice. But we now have concrete assurance that any
possible type can be cloned into a symbol table safely; all Types are
either built-in (available everywhere by design) or are clonable.

6a1a98c313 Fix for fuzzer-discovered use-after-free.
The inliner discovered that when a binary expression is inlined, its
type is not cloned into the destination's SymbolTable. This meant that
when the inlined-from function was later dead-stripped, the type pointer
would become dangling. Did a quick pass over inlineExpression and
inlineStatement and ensured that types are always copied.

Also found that `copy_if_needed` was making a copy of eligible types
each time one was encountered, instead of making one copy and reusing
it. This is fixed as well.

4cf85073e6 Enforce (valid) array sizes in many more places
Unsized arrays are now allowed in exactly one place: On the declaration
of an interface block. This satisfies the one existing use-case, which
is the gl_in (sk_in) declaration for geometry shaders. There is no other
useful scenario, and most of our backends don't support them anyway.

Several spots were using less strict checks when attaching sizes to
arrays, allowing for zero or negative-sized arrays, so those are all
fixed now.

The existing tests that initialize arrays are still a problem, because
Metal doesn't support that (neither does GLES2). Also, ArrayConstructors
has gone from generating an error in the Vulkan backend, to invalid
SPIR-V.

059bea1380 Simplify IRGenerator::coerce.
I started unpacking the mechanics of type coercion, and realized that
the second half of the function was looking up the Symbol for a Type
based on its name (Types are already Symbols), converting that Symbol
back into a Type (we started with a Type anyway), wrapping that Type
in a TypeReference, then calling that TypeReference (which always
calls convertConstructor).

This CL cuts out the middle steps and simply calls convertConstructor
directly. A test was added to confirm that an earlier error encountered
on the CQ is no longer occurring.

ce73961a7d Silence SkCodecPrintf on Android
Android is currently the only platform that defines
SK_PRINT_CODEC_MESSAGES, which turns SkCodecPrintf into SkDebugf. This
macro is used to print messages from the SkCodec (or its underlying
library). At one point, Android requested better diagnostic messages,
but to my knowledge, they have never been used to help fix a bug. They
do, however, contribute to the overall high noise ratio of Android
logcat output. This is especially distracting when running the
AImageDecoder fuzzer (ag/10666507).

be0b3b7363 Strip down SkSL::ExternalValues, limit them to functions
Previously ExternalValues were flexible, and could be used as raw values
(with the ability to chain access via dot notation), or they could be
callable. The only non-test use-case has been for functions (in
particles) for a long time. With the push towards SkVM, limiting
ourselves to this interface simplifies things: external functions are
basically custom intrinsics (and with the SkVM backend, they'll just get
access to the builder, and be able to do any math, as well as
loads/stores, etc).

By narrowing the feature set, we can rename everything to reflect that,
and it's overall clearer (the SkSL types now mirror FunctionReference
and FunctionCall directly, particularly in how they're handled by the
CFG and inliner).

f94348fdd5 Detect and report numeric overflows in the SkSL parser.
Previously, some types of overflow were detected, but most would assert
or silently generate invalid code. Now, the parser will properly report
an error if it encounters any integer that exceeds UINT_MAX or any float
that exceeds FLT_MAX.

This fixes test OverflowUintLiteral.sksl. Added a test for floats as
well, OverflowFloatLiteral.sksl.

OverflowIntLiteral.sksl does not fail yet, because its values are larger
than INT_MAX, not UINT_MAX. These are legal from the perspective of the
parser. This must be caught later at IR generation time.

0247e9ea1c Fix SPIRV bug constructing a constant vector from another vector
This fix is overly conservative in some situations (identity conversions
among vectors with the same component type), but fixes errors in two
existing unit test cases.

4d3bfc511d Make all fragmentProcessors implicitly nullable in SkSL
This feature had devolved to just an assert, and one that isn't really
necessary - all of Ganesh is built to handle any child processor being
null. The next step is to remove nullable types entirely -- a large
amount of code.

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.

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.

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.

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.

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.

1b27c3d7a3 Check array bounds when a constant array index is used.
This sort of error would be detected by most backend compilers. This
case was also detected by the bytecode generator. It's easy for us to do
a similar check during SkSL IR generation and report the error sooner.

Also, `convertIndex` had migrated a few hundred lines away from
`convertIndexExpression`, so I moved it back to live next to its parent.

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.

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.

arbitrarily-deep array dimensionality; there are many opportunities for

07bc9a27f5 GPU clear values: just 4 floats
We previously represented these as SkPMColor4f. However, upcoming
changes will add limited support for clearing/drawing to unpremul
dst. Just store the clear values as four floats without assigned
interpretation.

Also, noticed a bug by code inspection: we weren't accounting for
write view swizzle in GrRTC. Fixed and added gm to test.

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.)

We have several paths through the IR generator that create and process
array types; the unit test covers global and local variables, and array
on the type versus array on the variable.

SPIR-V previously didn't know what to think when it encountered a Type
with a typeKind of kEnum, and would abort. These are now treated as
32-bit signed integers.

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.

d0f712f3fe Add fix for fuzzer-discovered crash at oss-fuzz:27614.
The fuzzer managed to create a test case which temporarily evaluates to
expression `half2(half(0.2)) + 2` as it is optimized. This requires a
bunch of temporary nonsense math as the IR Generator is attempting to
simplify as it goes; various attempts to remove terms from the fuzzer
test-case would cause it to stop reproducing the error.

Constructor::getVecComponent assumed that any constructor with a single
scalar argument would always implement `getConstantFloat` and
`getConstantInt`; however, constructors themselves did not actually
implement these methods. This meant that nesting a scalar constructor
inside a non-scalar constructor would abort when it tried to deduce the
value inside the inner constructor.

This has been fixed by implementing `getConstantFloat` and
`getConstantInt` for Constructors. These methods will assert if the
constructor has more than one argument or is a non-scalar type. This
should allow any number of nested constructors, e.g.
`half4(half(half(half(1))))` should recursively evaluate properly,
should we somehow generate this as an intermediate expression.

7b239054d9 Revert "Replace skslc worklist files with -- delimited command lines."
This reverts commit 3e1b771ce4.

Reason for revert: Not working on Windows.

Original change's description:
> Replace skslc worklist files with -- delimited command lines.
>
> Command lines with delimiters are a simpler approach; they don't require
> a scratch file to be created and parsed. (I didn't consider this
> approach until after implementing worklists.)
>
> This also fixes a minor issue with result codes when processing multiple
> files at once; in particular, unit tests can ignore compile errors, but
> regular fragment processor compilation should treat compile errors as
> fatal and stop the build.

8f46ecc84f Remove two YUV effect GMs: yuv_to_rgb_effect and yuv_nv12_to_rgb_effect.
These aren't testing anything that isn't tested more thoroughly in other
GMs. This avoids having to update them as SkYUVAInfo is used more broadly
in the GPU backend.

e1bbd5c128 Disallow unsized array dimensions on size fields past the frontmost.
This was slightly complicated by the fact that this syntax indicates an
array with a known size:

    float[] x = float[](1, 2, 3, 4);

Of course, the size is 4; it's just never explicitly stated in the
code. (The SkSL parser never actually deduces the size, but it doesn't
apparently have a need to; we don't do much in the way of optimization
for arrays.) However, this prevents us from simply failing whenever we
parse "[]" in non-builtin code; we need to keep scanning and see if the
variable is initialized. We already check this in the
ArrayConstructors.sksl test file.

1d75778cbf Disallow opaque types in structs and interface blocks.
This is a followup to http://review.skia.org/335196. This detects opaque
types (samplers and textures) at parsing or IR generation time and
reports an error regardless of backend. This check occurs before Metal
or SPIR-V would have a chance to detect the error, so it changes their
output to a slightly more focused error message. The Metal/SPIR-V fix in
the prior CL is still a nice broad catch-all for preventing spurious
ABORTs, though.
