- Use much simpler method to update implicit array sizes.
The previous overly complicated method was error prone.
- Rationalize all use of unsized arrays.
- Combine decorations when generating SPIR-V, to simplify
adding extensions.
There a couple functional problems, which when reduced down also led to
some good simplifications and rationalization. So, this commit:
- corrects "mixed" functionality: int[A] f[B] -> f[B][A]
- correct multi-identifier decls: int[A] f[B], g[C] -> f and g are independently sized.
- increases symmetry between different places in the code that do this
- makes fewer ways to do the same thing; several methods are just gone now
- makes more clear when something is copied or shared
Reinforces that conversion rules are operation-specific.
Side effect is that HLSL logical-operator conversions are more direct
(e.g. float -> bool, rather than float -> int -> bool).
HLSL allows image and texture types to be templatized on sub-vec4 types,
or even structures. This was mostly handled already during creation of
sampling operations. However, for operator[] which can generate image
loads, this wasn't happening.
It also isn't very easy to do at that point in time, because operator[]
does not know where the results it produces will end up. They may be
an lvalue or an rvalue, and there's a post-process to convert loads to
stores. They may end up in atomic ops.
To bypass that difficulty, GlslangToSpv now looks for this case and
adds the appropriate conversion. LIMITATION: this only works for
cases for which a simple conversion opcode suffices. That is to say,
it will not work if the type is templatized on a struct.
- make it sharable with GLSL
- correct the case insensitivity
- remove the map; queries are not needed, all entries need processing
- make it easier to build bottom up (will help GLSL parsing)
- support semantic checking and reporting
- allow front-end dependent semantics and attribute name mapping
- 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.
