Constant.cpp will throw a floating point divide by zero if floating point exceptions are enabled in Win32 causing the program to crash. This fix manually checks the right-hand argument of the division and sets appropriate Infinity, Negative Infinity, or NAN as if the floating point exceptions were disabled.
This PR adds support for default function parameters in the following cases:
1. Simple constants, such as void fn(int x, float myparam = 3)
2. Expressions that can be const folded, such a ... myparam = sin(some_const)
3. Initializer lists that can be const folded, such as ... float2 myparam = {1,2}
New tests are added: hlsl.params.default.frag and hlsl.params.default.err.frag
(for testing error situations, such as ambiguity or non-const-foldable).
In order to avoid sampler method ambiguity, the hlsl better() lambda now
considers sampler matches. Previously, all sampler types looked identical
since only the basic type of EbtSampler was considered.
This change is helpful for integration with Chromium, which recently
added a compiler option to warn when compiling any source files which
use extended characters. In this case the offending character was a
single unicode dash in a comment.
- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.
This fixes various issues related to gcc's strict-aliasing warning
by using unions. It also handles various cases hit with
gcc's missing-declarations warning.
If a constant object was both an array and a structure, and was
indexed with a constant, the arrayness was ignored and the wrong
subconstant selected. This fixes that.
- moving offset calculations for std140/std430 from reflection to linkValidate.cpp
- applying the offset/align rules on top of std140/std430
- removing caching the structure's number of components (and correcting that this is components, not size)

- don't allow pre-array object versions to return a struct containing an array
- special case -2147483648 / -1
- include "~" in the full integer functionality checks
- handle multiple function parameters having the same name

This included
- encapsulating aggregate constants
- removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
- adding structure type comparison for independently declared structures that still might match types

- don't use [] for map lookups, it can modify the map
- copy up built-in symbols out of shared symbol table levels before modifying them
- enforce shallow vs. deep TType copies
- combine maxArraySize with the array dimensions vector, encapsulate
- remove chaining of array types

Added the built-in functions EmitVertex(), EndPrimitive(), barrier(), memoryBarrier(), memoryBarrierAtomicCounter(), memoryBarrierBuffer(), memoryBarrierImage(), memoryBarrierShared(), and groupMemoryBarrier().
Have not added any new built-in variables.
Also changed the linear performance relateToOperator() to a high-performance version.
