------- Comment #7 from abel at gcc dot gnu dot org 2008-09-22 06:20 ------- The patch implementing ia64 changes needed for the selective scheduler can be found at http://gcc.gnu.org/ml/gcc-patches/2008-08/msg01669.html. [The first version of the patch with some summary is at http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00117.html. What is changed from that summary is that per Ian's suggestion we call compute_alignments from machine_reorg manually instead of rearranging the pass sequence.]
I was going to ping them, but HJ did that first. It is important that we get that in for 4.4, because otherwise selective scheduler will be non-functional on ia64. However, I presume reviewing the changes will take some time, so it could make sense to fix this bug first. The patch for the bug is simple, and it is not a problem to revert it when committing the rest of sel-sched changes. On the sel-sched branch, I have restored the config/ia64/* files to be in line with mainline before merge. I will revert this on a branch in two-three days, so that the sel-sched branch will contain a fully functional selective scheduler on ia64. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37381
