https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-embedded/arachne-pnr-0_p20180827 overwrites user's optimization (-O*). Discovered on: amd64 (internal ref: guru_tinderbox) NOTE: (CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode This machine uses clang with CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types See also: https://archives.gentoo.org/gentoo-dev/message/dd9f2d3082b8b6f8dfbccb0639e6e240 https://wiki.gentoo.org/wiki/Modern_C_porting unless there are known issues with -O* configured by the user, the build system should not overwrite -O*.
