On an AMD64 (Opteron) system, the Solaris 10 assembler does not like what GCC
produces. This system has all patches applied for Solaris 10 U4. GCC 4.2.1
works very well on it.
Configured like:
/home/bfriesen/src/gnu/gcc-4.3.0/configure -program-suffix='-4.3.0'
--enable-threads --enable-version-specific-runtime-libs
--enable-languages='c,c++'
When compiling libgcc2.c this warning is produced for each compile:
"/tmp/bfriesen/ccK2JBM6.s", line 402 : Warning: Illegal subtraction - symbols
