Fixes issue #6898
The -emit-spirv-via-glsl slang-test option has been broken for
some amount of time. Tests that were using it were operating as
if using -emit-spirv-directly, leading to many duplicated tests.
After fixing the test option, there were an number of errors that
appeared as a result.
This change fixes the broken test option and the resulting test
errors. Some of the test errors revealed some legitimate issues,
such as:
-The GLSL bitCount instrinsic only supports 32-bit integers and
requires emulation for other bit widths.
-Emitting GLSL 8-bit and 16-bit glsl integer types did not emit
the proper extension requirements
-Emitting GLSL and casting for 16-bit integers was missing a
closing parenthesis.
-Missing profile for GL_EXT_shader_explicit_arithmetic_types
-Missing toType cases for UInt8/Int8 for the kIROp_BitCast case
in tryEmitInstExprImpl.bitcast require the input has same width with result type (#7018)2025-05-07T05:46:42+00:00kaizhangNV149626564+kaizhangNV@users.noreply.github.com2025-05-07T05:46:42+00:00urn:sha1:ccdb2e39da37753961f3694d0f90e676bf859006
bitcast requires the input has same width with result type, this PR ensures that we always lower the bitcast IR instruction satisfies this requirement.
Close #7017.
