Daiki Noda ac5a6d9ff5 build: fix RelWithDebInfo optimization flags #31802 ... Problem: RelWithDebInfo generates redundant flags: Compilation: /usr/bin/cc -O2 -g -Og -g The `CMAKE_C_FLAGS_RELWITHDEBINFO` variable is being modified in a way that caused duplicate `-Og` and `-g` flags to be added. The resulting flags were `-O2 -g -Og -g`. - `-Og` (Optimize for debugging) and `-O2` (Optimize for performance) are different optimization levels. We can't use both at once. - The duplicate `-g` flag is redundant and no effect. multiple -O flags has no effect for code, just redundant. > If you use multiple -O options, with or without level numbers, the last such option is the one that is effective. https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html Solution: Adjust the flags to use the more appropriate `-O2 -g`.
