The used UAV formats are explicitly added in the [require] section of
every test that uses them.
Some of these tests were failing on Intel UHD graphics 770 because of
missing support for additional UAV load types, explicitly requiring
these formats allows these tests to be skipped.
On shader_test files, now resources should be declared this way:
[texture n] -> [srv n]
[srv buffer n] -> [srv n]
[uav n] -> [uav n]
[uav buffer n] -> [uav n]
[vertex buffer n] -> [vb n]
[render target n] -> [rtv n]
The dimension (buffer or 2D) is now specified as an additional parameter
in the "size" directive:
For 2D resources:
size (n, m) -> size (2d, n, m)
For buffers:
size (n, 1) -> size (buffer, n)
The location of dxcompiler should be set during configuration with
'DXCOMPILER_LIBS=-L/path/to/dxcompiler', and then at runtime with
LD_LIBRARY_PATH, WINEPATH or PATH as applicable.
A new 'fail(sm<6)' decoration is needed on many shader declarations
because dxcompiler succeeds on many shaders which fail with fxc. The
opposite case is less common and is flagged with 'fail(sm>=6)'. A few
tests cause dxcompiler to crash or hang, so these are avoided using
[require], which now skips tests until reset instead of exiting. Also,
'todo(sm<6)' and 'todo(sm>=6)' are used to separate checking of results.
