#70846 made the
compiler_builtins
crate ignore the default codegen-units setting and instead always split each function into a different codegen unit.This unfortunately breaks
-Zprofile
which requires a single codegen unit per crate (see #71283). You can notice this when building withcargo -Zbuild-std
andRUSTFLAGS
containing-Zprofile
.This PR works around this issue by just ignoring
-Zprofile
for thecompiler-builtins
crate.
