Enable metal tests (#8446)

2025-09-30T18:21:27+00:00

Enables all tests/metal/ tests that can be easily enabled. These tests were not originally designed as render tests; they are generally being enabled for pipecleaning purposes, and will not be rigorously testing the corresponding funcitonality. Where they cannot be enabled as render tests, and a metallib test wasn't already enabled, a metallib test was enabled instead (where possible). Fixes #7892

Fix Metal 8-bit vector type names: emit char/uchar instead of int8_t/uint8_t (#8223)

2025-08-26T18:58:44+00:00

The Metal backend was generating incorrect type names for 8-bit vector types, causing compilation failures when targeting Metal. According to the Metal specification, 8-bit vector types should be named `charN` and `ucharN` (e.g., `char2`, `uchar3`) rather than `int8_tN` and `uint8_tN`. ## Problem When compiling Slang code with 8-bit vector types for Metal, the compiler would emit: ```metal uint8_t2 _S8 = uint8_t2(uint8_t(0U), uint8_t(16U)); int8_t3 _S9 = int8_t3(int8_t(0), int8_t(16), int8_t(48)); ``` But the Metal compiler expects: ```metal uchar2 _S8 = uchar2(uint8_t(0U), uint8_t(16U)); char3 _S9 = char3(int8_t(0), int8_t(16), int8_t(48)); ``` This caused errors like: ``` error: unknown type name 'uint8_t2'; did you mean 'uint8_t'? ``` ## Solution Modified `MetalSourceEmitter::emitSimpleTypeImpl()` to emit the correct Metal-specific type names for 8-bit types: - `kIROp_Int8Type` now emits `char` instead of `int8_t` - `kIROp_UInt8Type` now emits `uchar` instead of `uint8_t` This change only affects the Metal backend and ensures that vector types like `int8_t2`, `uint8_t3`, etc. are correctly emitted as `char2`, `uchar3`, etc. ## Testing - Added a new test case `tests/metal/8bit-vector-types.slang` to verify the fix - Re-enabled the previously disabled Metal test in `tests/hlsl-intrinsic/countbits8.slang` - Updated `tests/metal/byte-address-buffer.slang` to expect the correct type names - Verified that existing Metal tests continue to pass Fixes #8211. --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.

C-like emitter: Add parenthesis when combining relational and bitwise… (#6070)

2025-01-16T17:23:35+00:00

* C-like emitter: Add redundant parentheses in several cases This is required since the Dawn WGSL compiler requires parentheses even though precedence rules could resolve order of operations. This closes #6005. * Fix tests/metal/byte-address-buffer The output now includes parentheses around shift expressions appearing as operands in bitwise expressions, so update the test accordingly. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He
