I was trying to work around the problem described in PR 19120 by doing totaly
unoptimized build:
wilx@logout:::~/tmp/gcc-head/objdir> CFLAGS="-O0 -fno-omit-frame-pointer -g3"
BOOT_CFLAGS="-O0 -fno-omit-frame-pointer -g3" LIBCFLAGS="-O0
-fno-omit-frame-pointer -g3" ../srcdir/configure --disable-nls
--enable-version-specific-runtime-libs --enable-dwarf2 --with-cpu=pentium3
--with-arch=pentium3 --with-system-zlib --disable-shared --prefix=/home/4/wilx
--enable-languages=c,c++ --disable-sjlj-exceptions --enable-shared=libstdc++
--enable-shared=libobjc --with-gc=zone
make BOOT_CFLAGS="-O0 -fno-omit-frame-pointer -g3" CFLAGS="-O0
-fno-omit-frame-pointer -g3" LIBCFLAGS="-O0 -fno-omit-frame-pointer -g3" bootstrap
Yet still I get -O2 during compilation:
./xgcc -B./ -B/home/4/wilx/i386-unknown-freebsd4.10/bin/ -isystem
/home/4/wilx/i386-unknown-freebsd4.10/include -isystem

-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition
-isystem ./include -fPIC -pthread -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2
-D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../../srcdir/gcc -I../../srcdir/gcc/.

I think that you have closed this one a bit too quick. Have you actually tried
it? This is what I have used:
CFLAGS="-O0 -g3 -fno-omit-frame-pointer" BOOT_CFLAGS="-O0 -g3
-fno-omit-frame-pointer" LIBCFLAGS="-O0 -g3 -fno-omit-frame-pointer"
LIBGCC2_CFLAGS="-O0 -g3 -fno-omit-frame-pointer" make CFLAGS="-O0 -g3
-fno-omit-frame-pointer" BOOT_CFLAGS="-O0 -g3 -fno-omit-frame-pointer"
LIBCFLAGS="-O0 -g3 -fno-omit-frame-pointer" LIBGCC2_CFLAGS="-O0 -g3
-fno-omit-frame-pointer" bootstrap
CFLAGS="-O0 -g3 -fno-omit-frame-pointer" BOOT_CFLAGS="-O0 -g3
-fno-omit-frame-pointer" LIBCFLAGS="-O0 -g3 -fno-omit-frame-pointer"
LIBGCC2_CFLAGS="-O0 -g3 -fno-omit-frame-pointer" ../srcdir/configure
--disable-nls --enable-version-specific-runtime-libs --enable-dwarf2
--with-cpu=pentium3 --with-arch=pentium3 --with-system-zlib --disable-shared
--prefix=/home/4/wilx --enable-languages=c,c++ --disable-sjlj-exceptions
--enable-shared=libstdc++ --enable-shared=libobjc --with-gc=zone
And these are examples where the flags are not used:
gcc -c -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -fno-common
-DHAVE_CONFIG_H -DGENERATOR_FILE -I/home/4/wilx/include -I. -Ibuild
-I../../srcdir/gcc -I../../srcdir/gcc/build -I../../srcdir/gcc/../include
-I../../srcdir/gcc/../libcpp/include \
-o build/ggc-none.o ../../srcdir/gcc/ggc-none.c
gcc -c -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic
-Wno-long-long -Wno-variadic-macros -Wold-style-definition -fno-common
-Wno-error -DHAVE_CONFIG_H -I/home/4/wilx/include -I. -I. -I../../srcdir/gcc
-I../../srcdir/gcc/. -I../../srcdir/gcc/../include
-I../../srcdir/gcc/../libcpp/include c-parse.c -o c-parse.o
gcc -c -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic
-Wno-long-long -Wno-variadic-macros -Wold-style-definition -fno-common
-DHAVE_CONFIG_H -I/home/4/wilx/include -I. -I. -I../../srcdir/gcc
-I../../srcdir/gcc/. -I../../srcdir/gcc/../include
-I../../srcdir/gcc/../libcpp/include ../../srcdir/gcc/tree-ssa-loop-manip.c -o
tree-ssa-loop-manip.o
These ignore the flags that I pass to both configure and make bootstrap. Though
it is not that bad because it compiles the stuff without optimization anyway.
The next one though uses -O2 despite the use of LIBGCC2_CFLAGS that you have
suggested:
./xgcc -B./ -B/home/4/wilx/i386-unknown-freebsd4.10/bin/ -isystem
/home/4/wilx/i386-unknown-freebsd4.10/include -isystem
/home/4/wilx/i386-unknown-freebsd4.10/sys-include
-L/home/4/wilx/tmp/gcc-head/objdir/gcc/../ld -O2 -DIN_GCC -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition
-isystem ./include -fPIC -pthread -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2
-D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../../srcdir/gcc -I../../srcdir/gcc/.
-I../../srcdir/gcc/../include -I../../srcdir/gcc/../libcpp/include -DL_ctzdi2
-c ../../srcdir/gcc/libgcc2.c -o libgcc/./_ctzdi2.o
The -O2 option is part of the gcc/Makefile.in file.
