------- Additional Comments From hp at gcc dot gnu dot org 2005-02-25 15:35 ------- In response to comment #6: Building a CRIS toolchain with simulator (but see further below): The general steps are exactly as any other simulator target, follow <URL:http://gcc.gnu.org/simtest-howto.html>, though you need the cris-sim.exp as per <URL:http://gcc.gnu.org/ml/gcc-bugs/2005-02/msg00138.html> (now in dejagnu CVS; not on sourceware). Because the baseboard file is not in the installed dir, special steps are necessary: "mkdir ~/dejagnuboards" Put cris-sim.exp in ~/dejagnurc "echo 'set boards_dir ~/dejagnuboards' > ~/.dejagnurc" Then proceed as per simtest-howto.html
But you actually just need to build cc1 and observe the assembly I posted. And again, I think I need to point out that a bug in handling of *asm-declared registers* is unlikely to show "widespread carnage". But I certainly see how it can be overlooked and broken in tree-ssa cleanup operations! I have not tried reverting the patch but will do later, hoping it can convince you that the "reorganization" caused this regression (whether directly or indirectly exposing bugs elsewhere). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20204
