[IRBuilder] Generate nuw GEPs for struct member accesses (#99538)

2024-08-09T12:25:04+00:00

Generate nuw GEPs for struct member accesses, as inbounds + non-negative
implies nuw.

Regression tests are updated using update scripts where possible, and by
find + replace where not.

[CodeGen] Simplify codegen for array initialization (#93956)

2024-06-10T07:19:55+00:00

This makes codegen for array initialization simpler in two ways:
1. Drop the zero-index GEP at the start, which is no longer needed with
opaque pointers.
2. Emit GEPs directly to the correct element, instead of having a long
chain of +1 GEPs. This is more canonical, and also avoids regressions in
unoptimized builds from #93823.

OpenMP: Use inbounds in EmitOMPAggregateAssign

2023-01-13T00:03:10+00:00

This looked like a plausibly correct out of tree patch.
The changed testcases with the pragmas stripped out only use
inbounds GEPs so I assume this is correct.

[OpenMP] Codegen aggregate for outlined function captures

2022-09-15T00:54:05+00:00

Parallel regions are outlined as functions with capture variables explicitly generated as distinct parameters in the function's argument list. That complicates the fork_call interface in the OpenMP runtime: (1) the fork_call is variadic since there is a variable number of arguments to forward to the outlined function, (2) wrapping/unwrapping arguments happens in the OpenMP runtime, which is sub-optimal, has been a source of ABI bugs, and has a hardcoded limit (16) in the number of arguments, (3)  forwarded arguments must cast to pointer types, which complicates debugging. This patch avoids those issues by aggregating captured arguments in a struct to pass to the fork_call.
