9d74c28e82 [graphite] Move Recorder and Recording to public include.
This also hides the ctors for the respective classes so you can't just
arbitrarily make one outside of the factories.

3145cb8f4b [graphite] Add rtAdjust to metal program generation
With this CL, rt adjust is handled automatically by the backend of the
CommandBuffer when setViewport is called, so DrawPass and the
CommandBufferTest are updated to configure that (and the geometry of
command buffer test is rewritten to be in Skia's coord system instead
of NDC).

Currently, the metal command buffer uses push constants to set the
rtAdjust uniform. Hypothetically, D3D12 could use the root descriptor,
etc. There is some coupling here between the intrinsics the SkSL
programming environment operates in, and the backends configuring the
pipelines, but I don't think it's unreasonable and it seems cleaner
to me than having DrawPass bind and upload uniforms for all of the
intrinsics.

9a44a6bf4f [graphite] RenderStep handles local-to-device transforms
Passes the Transform for each draw to the RenderStep, to both
writeVertices and writeUniforms, since any given RenderStep could
choose to transform vertices on the CPU, pack the matrix as instance
attributes, or upload it as a uniform.

Also updates UniformManager to take the source data as const void*

030f8260a7 Add debug traces to an existing test.
This demonstrates how much additional non-trace code can be generated
when debug traces are turned on. A followup CL adds a setting to disable
`trace_var`, which eliminates a significant percentage of the additional
ops (at the cost of removing valuable debug info).

5588bdd72d Put function return values in a slot.
This shouldn't change code generation when debug traces are disabled.
When they are enabled, we now get trace_var opcodes emitted for every
return statement. Internally, this required a fair amount of refactoring
around how return values are passed around, but it should all be
functionally equivalent.

This new image filter constructor enables SkRuntimeEffects to be

lazily using the SkRuntimeShaderBuilder enabling the resulting
shader to consume the previous stage of the ImageFilter graph.

This relands commit ad9d774c1f after

f57140768e Allow setting a trace coordinate without a skvm::Builder.
SkRuntimeEffect users will be insulated from skvm and the Builder, so
they won't be able to make an skvm::Coord directly. Replace this with
an SkIPoint, and do the conversion inside the SkVM code generator.

This also removes the requirement of assigning a trace coordinate; if
no trace coordinate is set, (0, 0) will be used.

00aa1a9259 Prevent 'binding' and 'set' on struct/interface block fields
I should have realized the fuzzer would find this assert when I added
it. Now the front-end rejects these layout qualifiers on both struct
fields and interface block fields. LayoutInInterfaceBlock.sksl is a
reformatted version of the fuzzer input. LayoutInStruct is hand-crafted
to trigger the same failure on a different code path. Both would
previously assert in the SPIRV generator. Now, neither one gets that
far.

decorated this way (and we coalesce those into members of an interface
block).

Now, we only allow those layout qualifiers on variable types that will
remain top-level constructs in the back-end.

217347528b Improve redundant trace_var elimination.
Previously, we would avoid emitting redundant trace_vars by checking to
see if the slot is being assigned to the exact same Var.ID. However,
this had the potential to eliminate useful trace_vars:

- At the start of execution, slots all contain 0. Code which explicitly
  assigned a zero into a slot would not be shown in a trace. (So things
  like `color = half4(0,1,0,1)` would only emit traces for color.ga.)
- A function call's parameter slots are reused every time it is called,
  so calling a function twice would only emit traces for the parameters
  that aren't the same Val.ID as the previous call.
- A VarDeclaration inside a loop reuses its slot each time through the
  loop, even though conceptually it's a "new" variable.

We now track a slot's "written-to" status. At the start of execution,
no slots have been "written-to". These slots will always emit a
trace_var opcode (fixing the first issue). Also, issuing a function
call or declaring a variable will reset the "written-to" status of the
associated slots (fixing the second and third issues).

When the debugger is not in use, the written-to field is unused.

c809e5ba9f Optimize commutative operations in SkVM.
We now canonicalize commutative operations by ordering their value IDs.
The lower-numbered value ID is always placed first into a commutative
instruction. In other words, this instruction:
   bit_and result, v7, v5

Would be silently converted to this:
   bit_and result, v5, v7

This will allow these two logically-equivalent instructions to be
deduplicated:
   bit_and result, v7, v5
   bit_and result, v5, v7

Of course, deduplicating these ops can unlock additional free CSE/DCE.
The affected instructions are listed in http://review.skia.org/473238

626dbe195a Add test for commutative operations in SkVM.
SkVM should be able to optimize away these equivalent expressions:

	(intA & intB)   <->  (intB & intA)
	(intA ^ intB)   <->  (intB ^ intA)
	(intA | intB)   <->  (intB | intA)
	(intA + intB)   <->  (intB + intA)
	(intA * intB)   <->  (intB * intA)
	(intA == intB)  <->  (intB == intA)
	(intA != intB)  <->  (intB != intA)

These should be guaranteed by IEEE754 as well:

	(floatA + floatB)   <->  (floatB + floatA)
	(floatA * floatB)   <->  (floatB * floatA)

I've added a test to demonstrate existing behavior, which leaves these
optimizations on the table.

Within the SkVMCodeGenerator, we now have a new traceMask() call which
combines the current execution mask with the trace mask. Tracing opcodes
now pass the result of traceMask() instead of mask(). This will limit
trace data to the selected pixel, instead of tracing the entire draw.

14a487fd54 Replace getConstantSubexpression with getConstantValue.
The only type of expressions that getConstantSubexpression could ever
return are Literal and nullptr. getConstantValue now returns an
optional<double>; nullopt indicates a non-constant value in the slot.
This simplifies most use cases, and allows us to get rid of some extra
"zero" and "one" Literal objects in some of our Constructor classes.

This change fixes a recent fuzzer issue. The fuzzer had discovered that
calling `getConstantSubexpression` on a ConstructorCompoundCast that
contained a compile-time-constant value would return literals of the
wrong type (the cast was not applied). By nesting repeated matrix casts,
this type confusion could be turned into an assertion.

6df1871cc2 Replace fSkVMDebugTrace program setting with SkVMDebugInfo.
When calling ProgramToSkVM, you can now pass in a pointer to an
SkVMDebugInfo struct. Passing in this pointer now enables trace opcodes,
removing the need for a dedicated `fSkVMDebugTrace` flag.

In this CL, the struct is empty, but in followup CLs it will contain
mapping tables that can be used to translate trace instructions into
human-readable results (e.g. slot numbers to variable names).

1991780081 Update LoopFloat/LoopInt tests to reduce hoisting.
Previously, none of our `runtime` tests relied on the input coordinate
in any way, so all of the logic was hoisted above the main loop in every
test. This CL adds an artificial reliance on the input coordinate so
that we have at least some SkVM tests with real code in the main loop.
This lets us see debug trace instructions interleaved with real code.

The input coordinate is clamped against a known uniform value
(`colorGreen` always contains 0101) so that the final test output
remains consistent in practice.

Additionally, I noticed that this test was only enabled in ES3, but
it doesn't seem to have anything ES3-specific in it, so it's now
enabled across the board.

05c41162fb Allow inlining of functions with unassigned out-params.
Our inliner would ignore any functions with `inout` parameters, because
inlining them properly was more complex than just leaving the function
call. However, real-world code can sometimes contain helper functions
that have `inout` params that are never used at all (e.g. an uber-shader
with some features turned off).

We now read the ProgramUsage and check to see whether or not the
`inout`-qualified parameter is actually modified. If it's never changed,
the function now remains a candidate for inlining.

6ee5d9e3c9 Improve index-folding of arrays and matrices.
Yesterday's implementation was close but I realized later that it wasn't
quite ideal.
- Array index-folding was gated on `isCompileTimeConstant`, which is too
  strict. The real limitation is `hasSideEffects`. If an array contains
  a side-effecting expression, we should leave it alone. Otherwise it
  is safe to pluck out an element from the array and toss the rest.
- Matrix index-folding was gated on `getConstantSubexpression` for the
  extracted elements, but did not check the other elements at all. This
  was too lenient; we now only proceed to the folding step if
  `hasSideEffects` returns false.

I added some tests to verify the final behavior and also discovered a
small related issue. Diagonal matrices were not substituting literals
in for constant-values, which inhibited folding as well and would break
constant-expression evaluation. This is now fixed.

76c1ff1566 Optimize indexing into an array with a constant-expression.
Previously, SkSL was unable to resolve the constant expression `x[y]`
for a constant-array `x` and a constant-integer-scalar `y`. Now, if `x`
and `y` are known, we can replace `x[y]` with the indexed array element.

Note that we need to be careful here, as it's not a valid optimization
to eliminate array elements that have side effects. We preserve side-
effecting expressions using the comma operator.

Previously, we didn't have tests which leveraged constant-evaluation of

The test files now separate vector- and array-handling into separate
tests, and a ton of new cases have been added to ArrayFolding. The
ArrayFolding tests now require constant-evaluation of array indexing,
so they fail in this CL, but will be fixed in the followup CL.

6e6ae1b762 Fix inlined out-of-range vector access.
Previously, this code assumed that IndexExpression::Convert had done
range checking and that it was safe to access the base expression at
the passed-in index. The inliner violates this assumption, because it
can replace unknowns (where out-of-range access is undefined but non-
fatal) with knowns (where out-of-range access is forbidden).

We now do range-checking inside IndexExpression::Make and report the
error cleanly, instead of asserting inside of Swizzle::Make due to an
invalid component index.

3b6e07098b Enable constant-expression folding at all times.
In some contexts, we rely on constant expressions to fold in order for
SkSL to work properly. (e.g. an array size is allowed to be any
constant-expression in GLSL, but the compiler really needs to know the
actual size). Previously, turning off optimization would break several
tests. Now, constant-expression folding always occurs even when the
optimizer is disabled.

Note that disabling the optimizer isn't an end-user option, so this
only affects internal usage.

1f8c31b101 [infra] Add initial Bazel rules and files
These rules can be used to build our GMs on WASM+WebGL and
libskia.a with just the CPU backend (and most other features
turned off).

This can be done with the following commands:
  - bazel build //modules/canvaskit:gm-bindings-wasm --gpu_backend=gl_backend --with_gl_standard=webgl_standard
  - bazel build :skia-core --config clang

This pivots slightly from http://review.skia.org/463517
by using config_settings [1] instead of platforms for
the optional features that we control. This pivot was
suggested in [2]

We have BUILD.bazel files in many of the subdirectories
that specify filegroups for the appropriate files. In
an effort to make //BUILD.bazel more readable, it is
the responsibility of these subfolders to deal with
conditionally including certain .h or .cpp files.
This is done using select statements and config_settings
or platform constraints as necessary.

For example, src/gpu/BUILD.bazel will different private
filegroups for each of the supported gpu backends [3]
and a more-visible filegroup called "srcs" that has
the right selection of the private files to be used
for compilation.

An effort has been made to avoid using glob() in our
BUILD.bazel files. These file lists were made by using
`ls -1` and some regex to add in quotes. We might want
to make a helper script to assist with that, if necessary.

To specify which options we have, the settings in
//bazel/common_config_settings/BUILD.bazel have been
redesigned. They make use of a macro `string_flag_with_values`
that removes the boilerplate. Patchset 36 shows what the
file looks like w/o the macro.

The top level BUILD.bazel file will still need to use
some logic to handle defines, because local_defines is
a list of strings, not a list of labels [4].

Suggested Review Order:
  - WORKSPACE.bazel to see the new dependencies on the
    emsdk toolchain and bazel_skylib
  - bazel/common_config_settings/* to see the few settings
    defined (we have more to define, see BUILD.gn and
    //gn/skia.gni for ideas)
  - BUILD.bazel to see the "skia-core" cc_library rule.
    See also "gms" and "tests"
  - modules/canvaskit/BUILD.bazel to see the use of
    the emscripten "wasm_cc_binary" rule, which depends
    on the "skia-core", "gms", and "tests" rule. Note that
    it only builds some of the gms as a proof of concept.
  - The other BUILD.bazel files. Some of these are not

Much like http://review.skia.org/467759, this CL defensively guards
against programs which consume more space than is reasonable. Globals
exist outside of functions, so they wouldn't be caught by the stack size

7cde28909f Enforce basic limits on function stack size in SkSL.
Functions that declare variables totaling more than 100,000 slots will
now generate an error.

This is only a partial mitigation to the problem, as a sophisticated
attack could still chain/nest multiple functions together to consume
extremely large amounts of stack. However, this mitigation is still more
sophisticated than our peers; both WebGL and glslang are susceptible to
similar problems, and in the general case (ES3+ with full flow control)
it's intractable.

390edeb88d Fix fuzzer-discovered error with no-op arithmetic.
The fuzzer triggered this error in a strange way that involves parsing a
TK_INVALID token. The fuzzer's original input used \xFF bytes in the
shader text to do this. I replaced these with the ` character since it
behaved the same, but allows our test inputs to remain basic ASCII.

The root problem is that `cast_expression`, part of no-op arithmetic
simplification, can now fail because expressions like `int(4000000000)`
no longer get past Constructor::Convert. Previously we had assumed
`cast_expression` could never return null; now we check its result for
null before using it.

aa369d2b8e Fix error with inlined literals overflowing their types.
It's possible to write code containing errors that are only apparent
once the inliner runs. For instance, a function which takes a short and
returns its negative it is valid for most inputs, but undefined for
-32768 (because +32768 does not fit in a short). A function which takes
floats and casts them to ints is valid for many inputs, but not valid if
you pass in 5 billion.

This CL restructures our out-of-range integer error detection to report
errors cleanly in these cases instead of asserting. It also refactors
the range checking code to be usable in situations where we don't yet
have a Literal expression.

65a726bb49 Move GR_MAKE_BITFIELD_OPS and GrAlignTo to non-GPU files
These have been renamed SK_MAKE_BITFIELD_OPS and SkAlignTo
because nothing seemed particularly GPU/Ganesh specific to them.

I moved the latter to SkTypes.h because we have other align
code there and former to src/SkUtils.h because I didn't know

The primary motivation was removing the GrTypesPriv.h
include from src/core/SkBlockAllocator.h. I had attempted
some amount of #if SK_SUPPORT_GPU, but that's not as clean
here because both our CPU and GPU backends use the
SkBlockAllocator (as far as I could tell).

This also moves sk_memset* from SkUtils.h to SkOpts.h, because
SkOpts.h requires bringing in RasterPipeline, which seemed

4363cdb5ea Fix for fuzzer-discovered error with bitwise-not.
A recent CL (http://review.skia.org/464121) made it an error to coerce a
literal value to a type that cannot hold the value. The fuzzer found a
case where we assumed type-coercion of a literal would always succeed,
and failed to null-check the result. We now null-check the result.

able to assume that `simplify_negation` would always return a non-null

e82c1c11bc Add support for vk drm format modifiers.
On linux we need to support drm format modifiers on vulkan images. When
we have a modifier it can restrict the allowed usages/features of the
VkImage.

The current use case we have for images coming into skia that have
these modifiers are from video decoders. All these images are only used
as sampled images in draws and they have no filtering applied.
Therefore, for now, instead of tracking all format and modifier pairs
to know what is supported, we internally set these images to be external
which already restricts their use to basic in shader sampling.

Additionally in chrome, all these images are coming in ycbcr conversions
already which we treat as external.

These are not very interesting right now, because the in and out types

will return an array which casts each element from int-to-short or
float-to-half (or vice versa).

> does not actually work well on a lot of GPUs!

> - Compiles, but generates wrong result:
> 	RadeonR9M470X
> 	RadeonHD7770
>
> Since this isn't a pattern we expect to see in user code, we now report
> it as an error at compile time. mat2(vec4) is treated as an exceptional
> case and still allowed.

Previously, in public code, private types didn't exist anywhere in the
symbol table chain, and those names were free for the taking. Now, we
register them as invalid types in the public symbol table. This prevents
them from being used as variable names, and gives a more explicit error
if you try to use them as a type.

5420cbcf65 Match GLSL scoping rules more closely in SkSL.
GLSL treats builtin types and user-defined types differently; `int` and
`float` are keywords and cannot be used to name variables. However, it's
fine for a user type like `struct xyz` to be hidden by a variable
`int xyz` or even `xyz xyz` (i.e., a variable of type `struct xyz` named
`xyz`).

We now honor that distinction and include tests for it. This will fix
several ES2 conformance tests (local_struct_variable_hides_struct_type,
local_int_variable_hides_struct_type, etc.).

This is a reland of 35a74eab5d

116d2e0e48 Fix ES2 conformance test 'in_vs_no_in'.
SkSL treated these two functions as distinct, even though they are not:
    void func(in float x);
    void func(float x);

The `in` modifier on a function parameter is the default state, making
these two prototypes functionally identical. We now strip off an `in`
modifier on a function definition. This gives us three potential states
for each param: nothing (meaning `in`), `out`, and `inout`.

9fa47cc1c6 Make class members that are static constexpr also be inline.
This is in prep for compiling with -std=c++14 and -Wno-c++17-extensions
when building with clang. Chrome has encountered problems with
third_party headers that are included both in Skia and other Chrome
sources that produce different code based on whether preprocessor macros
indicate a C++14 or C++17 compilation.

In C++17 they are already inline implicitly. When compiling with C++14
we can get linker errors unless they're explicitly inlined or defined
outside the class. With -Wno-c++17-extensions we can explicitly inline
them in the C++14 build because the warning that would be generated
about using a C++17 language extension is suppressed.

We cannot do this in public headers because we support compiling with
C++14 without suppressing the C++17 language extension warnings.

c845272b4e Broke DSLWriter into two separate classes
As DSLWriter evolved, it ended up performing two unrelated duties:

1. Holding per-thread state which is referenced throughout SkSL
   (including non-DSL code)
2. DSL-specific utility functions

There's no reason for those to be contained in the same class, and
there's also no reason the per-thread state should be held in a
DSL-specific class. This breaks out an SkSL::ThreadContext class to hold
the state info, leaving the DSL utility functions behind in DSLWriter
(which should perhaps be renamed, but that's a job for a future CL).

6d0234673a Optimize away empty for loops.
The fuzzer has found that it can get timeouts in SkVM by nesting loops
very very deeply, then at the bottom of the chain, making an inside-out
loop that runs for zero iterations. This has a calculated unrolled-size
of zero, but SkVM would still think hard about unrolling the (ultimately
empty) outer loops.

SkSL now optimizes away unrollable loops that run for zero iteratinons,
as well as empty unrollable loops. This should eliminate the fuzzer's
troublesome construct entirely.

ff5bb37b72 Replace illegal DSLTypes with Poison types.
The fuzzer has been poking various holes in DSL by intentionally
creating illegal types (e.g. private or not ES2-compatible), then
finding ways to use those types, e.g. constructors or swizzles.

Previously we were mitigating those by calling `reportIllegalTypes` at
the locations where the type was used. Now, we detect the illegal type
usage at the source, and return a poison DSLType. This prevents the
illegal type from leaking out at all, and stops the problem at its
source. It also allows us to remove calls to `reportIllegalTypes`
sprinkled through the code, as those are now redundant.
