It would be better if this were an IR to IR test rather than HLSL to IR running the full pipeline.
DXC's hacked up SROA is quite messy and massively under tested. The ExtractIRForPassTest.py script should be able to turn this source into an IR test pretty easily.

Sure thing. Can I also keep this HLSL test?

Added an IR test. I want to keep the HLSL test too just to verify end-to-end.

Previously, global variables converted to
alloca's, their debug info is written as adbg.valuefor a fake local variable prefixed with "global.". This was only done for the entry function'sDISubprogram, which makes the variable inaccessible for all inlined function scopes.This change creates a
dbg.valuefor each inlinedDISubprogram, each pointing to a newDILocalVariablewith the inlinedDISubprogramas its scope.
