make profiledbootstrap broken?

make profiledbootstrap broken?

[Bernardo Innocenti]

Hello,

is it just me doing something wrong or the profiledbootstrap
feature is currently broken in mainline?

It seems some source files are missing the accompaning .gcda file:


stage1/xgcc -Bstage1/ -B/usr/local/src/gcc_combined/i386-linux-HEAD-install/i686-pc-linux-gnu/bin/ -c   -g -O2 -fbranch-probabilities -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Werror -fno-common   -DHAVE_CONFIG_H    -I. -I. -I../../combined-HEAD/gcc -I../../combined-HEAD/gcc/. -I../../combined-HEAD/gcc/../include  ../../combined-HEAD/gcc/resource.c -o resource.o
../../combined-HEAD/gcc/resource.c: In function `clear_hashed_info_for_insn':

Yes it is but a work around is to use --disable-werror.
The patch to really fix it is here: <http://gcc.gnu.org/ml/gcc-patches/2003-09/msg02061.html>.

Thanks,

I confirm your patch fixed the problem for me. Thanks!

The problem is that Makefile now incorrectly pass -Werror for
profilestage flags.  This is fixed by patch I sent some time ago but it
wasn't reviewed yet.  You may work around by disabling -Werror in
configure (don't remmber the name of flag)
