From: "raj dot khem at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/44290] New: arm linux kernel crahes when built with -fipa-sra Date: Thu, 27 May 2010 06:26:00 -0000 [thread overview] Message-ID: <bug-44290-10179@http.gcc.gnu.org/bugzilla/> (raw) While trying to boot linux 2.6.34 built with gcc from latest gcc-4_5-branch the kernel would not boot. Same kernel would work fine with gcc 4.4.4 Reducing to individual optimization phases. So far I have seen that when compiled with -O2 the kernel crashes however when I change the flags to -O2 -fno-ipa-sra then it works well. I don't have a small test-case as of now. I am trying to reduce it but it might take some time. Meanwhile I wanted to open the bug so that if someone else has information on similar issue can chime in. -- Summary: arm linux kernel crahes when built with -fipa-sra Product: gcc Version: 4.5.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: raj dot khem at gmail dot com GCC build triplet: x86_64-linux GCC host triplet: x86_64-linux GCC target triplet: arm-none-linux-uclibcgnueabi http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44290
