------- Comment #15 from lucier at math dot purdue dot edu 2009-02-12 16:35 ------- Some comments (a lot went on while I was sleeping):
1. Yes, this is similar to the test case of PR26854, but the C code generator has changed significantly since that test case was filed. I don't know if the changes in the code generator really affect what's happening here, however. 2. I'm trying to get a "moderately" sized test case that will compile in about 3GB of RAM, as Steven requested. (The test case from PR26854 takes at least 7GB of RAM to compile on ppc64.) 3. If the amount of memory and cpu time required by the test case at -O1 doesn't increase significantly when loop-invariant motion is performed on loops of size up to 10,000, then it would be good if the parameter at -O1 could be 10,000 instead of 100 (or at least larger than 100), as is suggested in the most recent patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39157
