Craig Tiller 1f85fb21f2 [metadata] Improve codegen for name lookups (#33237 ) The approach of doing a recursive function call to expand the if checks for known metadata names was tripping up an optimization clang has to collapse that if/then tree into an optimized tree search over the set of known strings. By unrolling that loop (with a code generator) we start to present a pattern that clang can recognize, and hopefully get some more stable and faster code generation as a benefit. <!-- If you know who should review your pull request, please assign it to that person, otherwise the pull request would get assigned randomly.

[metadata] Improve codegen for name lookups (#33237 )

The approach of doing a recursive function call to expand the if checks
for known metadata names was tripping up an optimization clang has to
collapse that if/then tree into an optimized tree search over the set of
known strings. By unrolling that loop (with a code generator) we start
to present a pattern that clang *can* recognize, and hopefully get some
more stable and faster code generation as a benefit.
