When preprocessing only, some tokens were emitted as <bad token>.
This fixes them to preserve their original content.
This supplants PR #182, with a correction and test results.
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)
The sequence
#define m()
int m"
creates a token of no length (a string of 0 size). Protect
against a string of 0 size as well as the existing protect
against a null string.
This would look ahead for a second #, for token pasting, and if not
found, backup one token. This is fine, unless at the end of line,
which would backup the #, rather than the look ahead.
Also, this allows turning on the error check for a failed assigment
when parsing.
This makes 39 HLSL tests have a working assignment that was previously
silently dropped, due to lack of this functionality.
- Support GL_AMD_shader_ballot (SPV_AMD_shader_ballot).
- Support GL_AMD_shader_trinary_minmax (SPV_AMD_shader_trinary_minmax).
- Support GL_AMD_shader_explicit_vertex_parameter
(SPV_AMD_shader_explicit_vertex_parameter).
- Support GL_AMD_gcn_shader (SPV_AMD_gcn_shader).
Added -C option to request cascading errors. By default, will exit early,
to avoid all error-recovery-based crashes.
This works by simulating end-of-file in input on first error, so no
need for exception handling, or stack unwinding, or any complex error
checking/handling to get out of the stack.
This is used by OpenGL, but not Vulkan.
Includes:
- atomicCounter, atomicIncrement, atomicCounterDecrement
- atomic_uint layout-offset checking
- AtomicStorage capability
Symbol table sharing has different sets of symbols for different
versions. This needs to take into account that SPIR-V has different
symbols than non-SPIR-V.
This checkin implements about half of the HLSL intrinsics for a subset of their
entire type support (but a useful subset). The uncommented lines in
TBuiltInParseablesHlsl::identifyBuiltIns shows which are connected.
