--- Comment #19 from Joshua Kinard <kumba at gentoo dot org> --- Created attachment 33165 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33165&action=edit Disassembly of the ASM from 'sln' compiled by a known working gcc-4.8.0. This is the objdump disassembly of the '__lll_lock_wait_private()' function from the sln binary from glibc, statically compiled, by a GOOD gcc-4.8.0 checkout (7882e02e) with commits 39a8c5ea, 974f0a74, 0f8e46b1, and 30c3c442 reversed.
