Multisample textures support a GetSamplePosition() method intended to query
positions given a sample index. This cannot be truly implemented in SPIR-V,
but #753 requested returning standard positions for the 1..16 cases, which
this PR adds. Anything besides that returns (0,0). If the standard positions
are not used, this will be wrong.
This should be revisited when there is a real query available.
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.
This needs some render testing, but is destined to be part of master.
This also leads to a variety of other simplifications.
- IO are global symbols, so only need one list of linkage nodes (deferred)
- no longer need parse-context-wide 'inEntryPoint' state, entry-point is localized
- several parts of splitting/flattening are now localized
This PR adds a CreateParseContext() fn analogous to CreateBuiltInParseables(),
to create a language specific built in parser. (This code was present before
but not encapsualted in a fn). This can now be used to create a source language
specific parser for builtins.
Along with this, the code creating HLSL intrinsic prototypes can now produce
them in HLSL syntax, rather than GLSL syntax. This relaxes certain prior
restrictions at the parser level. Lower layers (e.g, SPIR-V) may still have
such restrictions, such as around Nx1 matrices: this code does not impact
that.
This PR also fleshes out matrix types for bools and ints, both of which were
partially in place before. This was easier than maintaining the restrictions
in the HLSL prototype generator to avoid creating protoypes with those types.
Many tests change because the result type from intrinsics moves from "global"
to "temp".
Several new tests are added for the new types.
Rationalizes the entire tracking of the linker object nodes, effecting
GLSL, HLSL, and SPIR-V, to allow tracked objects to be fully edited before
their type snapshot for linker objects.
Should only effect things when the rest of the AST contained no reference to
the symbol, because normal AST nodes were not stale. Also will only effect such
objects when their types were edited.
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.
