This is broken down into 6 patches. odc_1288: - Fix successor list in Do_tail_duplication.
odc_1392: - skip a corner case that does not need a normalization. - avoid a seg fault when a SC node does not have a representative block. odc_1393: - avoid using a deleted DO_LOOP WHIRL. odc_1396: - skip loops that are not flagged LOOP_PRE_DO for normalization. odc_1398: - avoid using list iterator to prevent access to deleted SC nodes and etc. odc_1400: - Add a heuristic to turn off level 2 loop fusion if there exists a write to formal paramters. This is a workaround for a program bug in CPU2006 gameness. - Flag pass-by-reference parameters in scalarization to avoid deleting stores that appear dead but actually not since the variable is passed by reference -----Original Message----- From: Sun Chan [mailto:sun.c...@gmail.com] Sent: Monday, May 23, 2011 4:52 PM To: Ye, Mei Cc: open64-devel@lists.sourceforge.net Subject: Re: [Open64-devel] code review: bug fixes for proactive/aggressive loop fusions I understand it is simpler for testing purposes. For later on bug triage and identification, it would be better if checkins are done one item at a time (except for hugh source changes). Is it possible to separate the changes by item?
