Hi, Martin A few PowerPC-specific testcases started failing yesterday on AIX with a strange failure mode: the compiler runs out of memory. As you may expect from telling you this in an email reply to your patch, I have bisected the failure and landed on your commit. I can alternate between the previous commit and your commit, and the failure definitely appears with your patch, although I'm unsure how your patch affected memory allocation in the compiler. Maybe moving the code changed a type of allocation or some memory no longer is being freed?
Previously, compiler bootstrap and all testcases ran with a data size of 1GB. After your change, the data size required for those particular testcases jumped to 2GB. The testcases are gcc/testsuite/gcc.target/powerpc/rlwimi-[012].c The failure is cc1: out of memory allocating 65536 bytes after a total of 1608979296 This seems like a significant memory use regression. Any ideas what happened? Thanks, David
