- correct inheritence (or not) of the right XFB buffer
- compute implicit stride (fixes#1212)
- semantic check block-member redeclarations
- inherit stride from a member
- fixes#1209, addresses most of #1187
- only query feature availability on seeing the feature
(was doing it for every single token)
- correct case-sensitive checks for multi-character suffixes
- partially addresses #1209 and #1187
- only query 64-bit extension on seeing use of a 64-bit literal
(was doing it for every single token)
- correct HLSL acceptance of 64-bit literal syntax (still an int though)
- error on overflow of 32-bit literal type
The grammar for no semicolon and no object name for cbuffer/tbuffer
was correct, but the production still skipped the anonymous declarations
if an identifier followed.
Set type to r-value resulting from indexing vector, to prevent
float->uint conversion when source is already uint. Resulting
OpConvertFToU would otherwise fail validation because source is
already uint.
For LoadN, incorrect uint->float->uint can be avoided; fixing
potential truncation of big integer values.
Also, only emit this XFB information where the SPIR-V spec says
it should be emitted: essentially, on objects.
This and the previous commit together fix#1185.
In DX10/DX11 you can only output RT/Viewport indices from GS; however,
DX11.4/DX12 add support for outputting these from VS as well.
This is supported by Vulkan if the relevant extension is available, and
by MSL and by MSL (which you can cross-compile to via SPIRV-Cross).
Some stage (e.g, hull shaders) have arrayed builtin outputs (e.g, position).
When copying from the internal structure to the split form, it is necessary
to propagate that indirection to the actual arrayed outputs. This was not
happening.
Addresses #1181
This makes struct returns from functions work, but breaks
structs containing arrays, due to limitations in subsequent
transforms in spirv-opt. This is expected to be fixed soon.
Adds command line options:
--invert-y
--iy
(synonyms) which invert position.Y on vertex shader output. Handles these cases:
* Direct single variable return
* Member of direct returned struct
* Single variable output parameter
* Member of struct output parameter
API:
// Enables position.Y output negation in vertex shader
void TShader::setInvertY(bool invert);
Fixes#1173
