This change adds support for function linkage and visibility and related
attributes. Most of the test changes are generalizations to allow
'dso_local' to be accepted where we aren't specifically testing for it.
Some tests based on CIR inputs have been updated to add 'private' to
function declarations where required by newly supported interfaces.
The dso-local.c test has been updated to add specific tests for
dso_local being set correctly, and a new test, func-linkage.cpp tests
other linkage settings.
This change sets `comdat` correctly in CIR, but it is not yet applied to
functions when lowering to LLVM IR. That will be handled in a later
change.
This change adds support for the CIRGlobalValueInterface and attributes
for visibility and comdat to GlobalOp.
The comdat attribute isn't correctly calculated yet, but it was required
for the CIRGlobalValueInterface interface. There are also some cases
where dso_local isn't set correctly, but it is better than it was before
this change. Those issues will be addressed in a future patch.
This adds alignment support for GlobalOp, LoadOp, and StoreOp.
Tests which failed because cir.store/cir.load now print alignment were
updated with wildcard matches, except where the alignment was relevant
to the test. Tests which check for cir.store/cir.load in cases that
don't have explicit alignment were not updated.
New tests for alignment are alignment.c, align-load.c, and
align-store.c.
This introduces MLIR aliases for ClangIR record types. These are used in
the incubator and having skipped over them upstream is causing the tests
to diverge.
This change adds minimal support for structure types. To keep the
initial change small, only incomplete declarations are being supported
in this patch. More complete support will follow.
