------- Comment #6 from pinskia at gcc dot gnu dot org 2007-02-16 22:29 ------- libcpp should be use BOOT_CFLAGS in 4.1.0 and before. In 4.2.0 and above the toplevel bootstrap allows libcpp to be compiled three times.
Second there is TARGET_CFLAGS also which is used to compile target libraries. >Here the compiler gets "-ffunction-sections -fdata-sections -O2" prepended. > AFAIK the first two flags currently only make sense on Suns where the linker > can actually use that information (according to the manpage). GNU's binutils (ld) does support the GCing of sections. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30810
