I added
.ifdef WITH_DETERMINISTIC
CXXFLAGS+=-frandom-seed=\"${.IMPSRC:S/^${.CURDIR}\///}\"
.endif
to lib/clang/clang.build.mk
and "WITH_DETERMINISTIC=true" to src.conf, but apparently the flag isn't being
propagated to clang.build.mk. However it is being picked up if I pass it on the
command-line:
make WITH_DETERMINISTIC=true buildworld
Why isn't the flag available in clang.build.mk?
