From: "b.grayson at samsung dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/58523] New: ARM and AArch64: -fsection-anchors doesn't seem to work Date: Wed, 25 Sep 2013 06:20:00 -0000 [thread overview] Message-ID: <bug-58523-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58523 Bug ID: 58523 Summary: ARM and AArch64: -fsection-anchors doesn't seem to work Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: b.grayson at samsung dot com Target: arm, aarch64 Build: gcc-4.9-20130915-arm-linux-gnueabhihf, gcc-aarch64-4.9-20130602/aarch64-linux-gnu-gcc Created attachment 30890 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30890&action=edit Test C file with two global variables, and a use of both of them I've tried compiling with -fsection-anchors in several different releases of gcc for ARM and now for aarch64, and it seems the optimization is not kicking in for scenarios where it should. I looked through the gcc/config directories, and the support seems to be there. Here is a simple testcase. The resulting assembly (not posted here, according to bug-reporting guidelines) does a full address-generation for variable a, and then again for variable b.
