These may happen when storing to structured buffers, and we are not
handling them properly yet. The included test reaches unreacheable code
before this patch.
Storing to buffers is complicated since we need to split the index
chain in two paths:
- The path within the variable where the resource is.
- The subpath to the part of the resource element that is being stored
to.
For now, we will emit a fixme when the index chain in the lhs is not a
direct resource access.
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.
