Intermediate output from gcc-9.3.0 compiling libgcc2 during bootstrap
Attempting to bootstrap gcc 9.3.0 (and same problem with gcc 10.2.0) on
sparc-sun-solaris2.11 system fails at the point of compiling libgcc2.c for
_ffssi2 as the compiler generates a .group directive which is not understood by
the binutils-2.35 as.
Configured with:
'../gcc/configure' '--prefix=/opt/gcc-9.3' '--disable-werror'
'--disable-checking' 'CC=gcc' 'CXX=g++' '--disable-multilib'
'--build=sparc-sun-solaris2.11' 'buil
d_alias=sparc-sun-solaris2.11' '--enable-languages=c,c++,lto'
