Hi, pgcc team,

I tried to compile pgcc-1.1 based on egcs-1.1b on a PPro-solaris-x86
system. The gas-2.9.1 (plain binutils-2.9.1 from prep.ai.mit.edu, no
H.J. Lu bugfixes) binary is installed in

/sw/i86_56/pgcc-1.1b/i686-pc-solaris2.6/bin/as

so pgcc will use gas as assembler.

make bootstrap fails.

The configuration is as follows:

CC=gcc CXX=g++ CFLAGS='-O3 -march=pentiumpro' \
CXXFLAGS='-O3 -march=pentiumpro' ./configure \
--prefix=/sw/i86_56/pgcc-1.1b --host=i686-pc-solaris2.6 --enable-haifa

where gcc is gcc-2.8.1 configured for i686-pc-solaris2.6.

I have also tried

CC=ecc CXX=e++ CFLAGS='-O3 -march=pentiumpro' \
CXXFLAGS='-O3 -march=pentiumpro' ./configure \
--prefix=/sw/i86_56/pgcc-1.1b --host=i686-pc-solaris2.6 --enable-haifa

where ecc is egcs-1.1b configured for i686-pc-solaris2.6. I have also
tried both of the above configurations with and without --enable-haifa.

Typing

make LANGUAGES='c c++ f77' bootstrap

results in the following error while compiling the stage2 compiler
(that means ./xgcc is compiled with stage1/xgcc):

gmake: *** [bootstrap] Error 2

If I configure without -march=pentiumpro in the CFLAGS and CXXFLAGS
everything compiles fine.




While compiling pgcc I saw the following warning, which is, in my eyes,
not only one of those warnings which are not important.

Occured in the 'gcc' directory:

gcc -c  -DIN_GCC    -g  -DHAVE_CONFIG_H -DHAIFA     -I. -I. -I./config reg-stack.c
reg-stack.c:236: warning: `BLOCK_NUM' redefined
basic-block.h:189: warning: this is the location of the previous definition



I hope this is enough to trace back what's going on here. If you need
further information (for example the produced binaries or
preprocessed files) feel free to ask me (frohlich AT na DOT uni-tuebingen DOT de).


Regards,

Mathias Fr"ohlich
