- Subject: Vectorization of strided access and bootstrap failure problem
The patch that enables vectorization of strided accesses (
http://gcc.gnu.org/ml/gcc-patches/2006-03/msg01679.html) is ready to be
committed to mainline. I incorporated the comments from the review, and re
tested with current mainline on x86 and ppc-linux (bootstrap + testsuite).
However, with current mainline, and with this patch bootstrap *with
vectorization enabled* fails on x86. It seems to me that this is the same
failure we've had for a while on mainline on ppc-linux, as reported in
pr28752, which has nothing to do with this patch (probably just exposed by
it).
I'm thinking, if no objection (within, say, 48 hours), to commit the patch
despite the above, while I continue to try to track down the cause of the
bootstrap failure with vectorization enabled.
