This is the GCC used for compiling illumos.
The il-* branches contain the the patches used for building illumos, which
are rebased versions of those used for Solaris/OpenSolaris, and then
additional changes. The versions actually in use are tagged with
il-VERSION-ilN where N version the illumos changes over the GCC version in
question.
The wip/* branches are works in progress and should never be used
The codesourcery/* and sun/* branches contain the original GCCs as patched by
CodeSourcery and Sun Microsystems for use compiling Solaris and OpenSolaris as
was, and the GCCFSS patches of Sun's
When building the compilers for illumos use the flags generally used are:
i386
../../configure --prefix=/opt/gcc/$VER --with-as=/usr/sfw/bin/gas --with-gnu-as \ --with-ld=/usr/bin/ld --without-gnu-ld --enable-languages="c,c++,objc" \ --enable-shared --with-mpfr-include=/usr/include/mpfr \ --with-gmp-include=/usr/include/gmp \ --with-pkgversion="Illumos $(git describe --all)" \ --with-bugurl="http://github.com/richlowe/gcc/issues"
sparc
../../configure --prefix=/opt/gcc/$VER --without-gnu-as --with-as=/usr/ccs/bin/as" \ --with-ld=/usr/bin/ld --without-gnu-ld --enable-languages="c,c++,objc" \ --enable-shared --with-mpfr-include=/usr/include/mpfr \ --with-gmp-include=/usr/include/gmp \ --with-pkgversion="Illumos $(git describe --all)" \ --with-bugurl="http://github.com/richlowe/gcc/issues"
Please use the correct --with-bugurl and --with-pkgversion flags as
appropriate for any modifications you make, but please also be sure that they
accurately describe what is in use (ie, are not left at the defaults) either.
