[libcxx-commits] [PATCH] D122397: [libc++] Use __builtin_expect and __builtin_assume in _LIBCPP_ASSERT

[Arthur Eubanks via Phabricator via libcxx-commits]

aeubanks added a comment.

were there any benchmarks showing that this was beneficial? as discussed in https://discourse.llvm.org/t/llvm-assume-blocks-optimization/71609, sprinkling assumes everywhere is not necessarily a worthwhile tradeoff and perhaps the default should be to not add assumes everywhere
