Matthew Denton 89ef2812 2024-06-26T11:19:54 ESSL -> WGSL: unary and binary exprs, operators, array access Array indexing is always checked to be within bounds. For runtime-sized arrays, this requires emitting a clamp(). For now this includes a bug the left-side-expression (the array itself) has any side effects, which shouldn't actually be possible but may be in future versions of WGSL. Implementing unary, binary, and remaining aggregate expressions requires implementing operators, many of which do not have exact corresponding versions between GLSL and WGSL. This implements many operators but for simplicity leaves some unimplemented and some half-implemented. See WGSLOutput_test.cpp for some code examples.

Matthew Denton 7ca9f46a 2024-06-21T13:09:24 ESSL -> WGSL: Emit func calls, struct access, constants Also includes constructor calls, swizzles, and a slightly incorrect version of the ternary operator. The ternary operator doesn't exist in WGSL, only a non-short-circuiting select() builtin. For now the ternary is implemented with select() but that isn't correct if any of the true/false expressions have side effects, and may have perf implications by computing both true/false expressions. Constants are mostly done after this, however NaN and infinity are not valid constants in WGSL and it's unclear what we can do about this as WGPU implementations are allowed to assume NaNs and infinities are never operated on.

Kimmo Kinnunen 18fa02be 2024-03-12T10:23:55 Rewrite exprs using separated decl variables Rewrite expressions that use the rewritten struct declaration variables. Declaration that specfies a struct and defines multiple variables will get its variable declarations separated. The type of the variable changes when a struct specifier is removed for the second and rest of the variable declarations. The type of the variable changes also when a anonymous struct is named. The expressions that used the separated variables used the old struct as their types. Fix by using TIntermRebuild. Upon creating a new symbol node referencing the new type, the rebuilder will instantiate also all the needed intermediate nodes, which then get the correct struct type. For consistency, fix the case of anonymous struct -> named struct transform naming the variables similar to named struct separation. Consider base case: struct S { .. } a, b; -> struct S { .. } a; S b; Compare against case: struct { .. } a, b; Before, inconsistency: struct s1 { .. }; s1 a; s1 b; After, fixed: struct s1 { .. } a; s1 b; Bug: angleproject:8590 Change-Id: Iffb0ef4441d6021e076b04485b808b26a7fa4dcb Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/5365201 Auto-Submit: Kimmo Kinnunen <kkinnunen@apple.com> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Kimmo Kinnunen <kkinnunen@apple.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>

By limiting the size of private variables to 32KB, this limitation is indirectly enforced.

Stephen White 3892ac14 2023-10-12T13:35:33 Do not flush normal float constants to zero. It's ok to flush denormalized constants to zero. It's not ok to flush perfectly valid normal float constants >= FLT_MIN to zero. Two problems: 1) Values when parsed as doubles with a value less than FLT_MIN are being flushed to zero. This is incorrect when the comparison is done in double, since some values below FLT_MIN in double are equal to FLT_MIN when cast to float. The fix is to perform the comparison in float. 2) Values with a decimal exponent less than FLT_MIN_10_EXP are being flushed to zero. FLT_MIN_10_EXP is -37 but FLT_MIN is 1.1754943E-38. 10^-37 may be the "minimum negative integer such that 10 raised to that power is a normalized float", but being constrained to powers of ten it's above FLT_MIN (which is 2^-126). Since this comparison is done before #1 above, it's only present (AFAIK) to ensure that the exponent will not make the pow() function overflow. Comparing against -38 (FLT_MIN_10_EXP - 1) instead will do the trick.

Shahbaz Youssefi 6f80f0f0 2022-08-06T02:29:19 Translator: Clean up the compile flag passing interface Historically, compile flags were sent to the translator as a bitmask. Recently, we were getting close to running out of bits. Additionally, direct-to-metal work had started to introduce constants to be passed to the translator, which were misplaced in ShBuiltInResources and Caps. Recent work on Pixel Local Storage adds even more constants, aggravating the situation. In this change, the interface to passing compile flags is reworked. A struct is passed (instead of a bitmask) that has one bit for each flag. This can be indefinitely extended. Additionally, the constants needed by metal and PLS are also placed in this struct. In turn, the backends can set these options directly, and don't have to hack them into Caps to further get hacked into ShBuiltInResources.

Shahbaz Youssefi c5271e8e 2022-04-04T23:28:35 Vulkan: Emulate GL_KHR_blend_equation_advanced Based on a change by Brandon Schade <b.schade@samsung.com> In the translator, when advanced blend is enabled, an input attachment is added. Based on the listed advanced blend equations, emulation code is added that performs those equations' functions. The blend equation itself is passed through a driver uniform. Note that the advanced blend extension only allows a single output to use advanced blend, and that should be at location 0. In the Vulkan backend, when advanced blend is used, the driver uniform to select the equation is updated and normal blending is disabled.

Shahbaz Youssefi 3036e090 2021-07-29T15:55:39 Vulkan: Direct SPIR-V Gen: Support the precise keyword The precise keyword is different in GLSL in that it defines what arithmetic operations _that have led to the value being assigned to a variable_ should be done precisely (i.e. not "contracted"). A tree traverser is implemented that detects precise access chains and applies precise-ness to the right hand side of assignment expressions to said access chains. This is only done if the shader uses the precise keyword in the first place. The algorithm for this is inspired by the implementation in glslang. This change additionally: - Fixes parser to allow precise on function parameters - Fixes GLSL code generation to output precise on struct members and function parameters.

Shahbaz Youssefi 05eb0a32 2021-07-19T16:14:34 Translator: Allow subpassLoad in AST in ESSL subpassLoad is available to desktop GLSL, but not GLSL ES. With this change, subpassLoad is made available internally to the AST so that framebuffer fetch's use of this built-in can be simplified. Additionally, this makes the tree more consistent in that there's no function call without a corresponding function declaration. A follow up change will add an AST validation to enforce this.

Taken from Kyle Piddington's CL: https://chromium-review.googlesource.com/c/angle/angle/+/2857366/ The goal of this CL is to merge the metal backend code in a state that compiles, but not to switch the Metal backend over to using the direct-to-metal backend yet.

Instead, gen_builtin_symbols.py automatically generates Ops for every built-in function and generates the TOperator enum accordingly. This simplifies SPIR-V code generation by allowing switches to be used on operators instead of string comparisons.
