------- Comment #4 from hailijuan at gmail dot com 2009-09-24 09:50 -------
There is another problem with "gcc -m64 -pg" since 4.4.0, seen from below:
# file
/import/dr3/i386/gcc-4.4.0/lib/gcc/i386-pc-solaris2.11/4.4.0/amd64/gmon.o
/import/dr3/i386/gcc-4.4.0/lib/gcc/i386-pc-solaris2.11/4.4.0/amd64/gmon.o:
ELF 32-bit LSB relocatable 80386 Version 1
Seen from gcc building log, gcc didn't build gmon.o with m64 as expected. Since
4.4, gcc/config/i386/t-sol2 has been moved to libgcc/config/i386/t-sol2.
However the flags for gmon.o turned to be empty.
Any comments on the issue? Thanks,
