QUOTE from man src.conf :
To be able to build the system, either gcc
or clang bootstrap must be enabled unless an alternate compiler
is provided via XCC.
END QUOTE
QUOTE from man src.conf :
The CCACHE_COMPILERCHECK
option defaults to content when using the in-tree bootstrap
compiler, and mtime when using an external compiler. The
CCACHE_CPP2 option is used for Clang but not GCC.
END QUOTE
With clang/clang++ 11's change to what -O means, I'm not sure about
the following from man make.conf :
QUOTE from man make.conf
CFLAGS (str) Controls the compiler setting when compiling C code.
Optimization levels other than -O and -O2 are not
supported.
END QUOTE
Same here:
QUOTE from man make.conf
COPTFLAGS (str) Controls the compiler settings when building the
kernel. Optimization levels above [-O (-O2, ...)] are not
guaranteed to work.
