The use of the hlsl_semantic.reported_duplicated_output_next_index field
allows reporting multiple overlapping indexes, such as in the following
vertex shader:
void main(out float1x3 x : OVERLAP0, out float1x3 y : OVERLAP1)
{
x = float3(1.0, 2.0, 3.2);
y = float3(5.0, 6.0, 5.0);
}
apple.hlsl:1:41: E5013: Output semantic "OVERLAP1" is used multiple times.
apple.hlsl:1:13: First use of "OVERLAP1" is here.
apple.hlsl:1:41: E5013: Output semantic "OVERLAP2" is used multiple times.
apple.hlsl:1:13: First use of "OVERLAP2" is here.
While at the same time avoiding reporting overlaps more than once for
large arrays:
struct apple
{
float2 p : sv_position;
};
void main(out apple aps[4])
{
}
apple.hlsl:3:8: E5013: Output semantic "sv_position0" is used multiple times.
apple.hlsl:3:8: First use of "sv_position0" is here.
Thanks to Giovanni for the second set of tests! Note that the
tolerance for the final pixel was set much higher than the others;
this test seems to be an issue for some devices (in my case, a 7900
XTX running RADV).

The descriptor component of struct d3d12_desc is replaced with a union
containing a pointer which can be swapped out using
InterlockedExchangePointer(). To make it safe to increment the refcount
of such an object it is necessary to cache freed objects. Elimination
of the descriptor mutexes on games which use multithreaded descriptor
writes nearly doubles framerate on recent hardware.
Eliminates vk_sets_mutex. Performance on average may be lower until
the descriptor mutexes are replaced and Vulkan writes are buffered
to reduce thunk calls.
Fix a compile warning:
