  17 +This is the GCC used for compiling illumos.
  18 +
  19 +The `il-*` branches contain the the patches used for building illumos, which
  20 +are rebased versions of those used for Solaris/OpenSolaris, and then
  21 +additional changes.  The versions actually in use are tagged with
  22 +`il-VERSION-ilN` where _N_ version the illumos changes over the GCC version in
  23 +question.
  24 +
  25 +The `wip/*` branches are works in progress and _should never be used_
  26 +
  27 +The `codesourcery/*` and `sun/*` branches contain the original GCCs as patched by
  28 +CodeSourcery and Sun Microsystems for use compiling Solaris and OpenSolaris as
  29 +was, and the GCCFSS patches of Sun's
  30 +
  31 +When building the compilers for illumos use the flags generally used are:
  32 +
  33 +i386
  34 +~~~sh
  35 +../../configure --prefix=/opt/gcc/$VER --with-as=/usr/bin/gas --with-gnu-as \
  36 +   --with-ld=/usr/bin/ld --without-gnu-ld --enable-languages="c,c++,objc" \
  37 +   --enable-shared  --with-mpfr-include=/usr/include/mpfr \
  38 +   --with-gmp-include=/usr/include/gmp \
  39 +   --with-pkgversion="Illumos $(git describe --all)" \
  40 +   --with-bugurl="http://github.com/richlowe/gcc/issues"
  41 +~~~
  42 +
  43 +sparc
  44 +~~~sh
  45 +../../configure --prefix=/opt/gcc/$VER --without-gnu-as --with-as=/usr/ccs/bin/as" \
  46 +   --with-ld=/usr/bin/ld --without-gnu-ld --enable-languages="c,c++,objc" \
  47 +   --enable-shared  --with-mpfr-include=/usr/include/mpfr \
  48 +   --with-gmp-include=/usr/include/gmp \
  49 +   --with-pkgversion="Illumos $(git describe --all)" \
  50 +   --with-bugurl="http://github.com/richlowe/gcc/issues"
  51 +~~~
  52 +
  53 +Please use the correct `--with-bugurl` and `--with-pkgversion` flags as
  54 +appropriate for any modifications you make, but please also be sure that they
  55 +accurately describe what is in use (ie, are not left at the defaults) either.
