There was a problem hiding this comment.
LGTM
FWIW, I wasn't sure what the .ll test was testing (mostly through my ignorance), but I checked out the branch and reverted the functional changes and that test started failing, which convinced me at least that it is testing something.
I would recommend getting a review from someone more familiar with the codebase than I am!

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.
