Author: jakub Date: Tue May 11 18:22:52 2010 New Revision: 159289 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=159289 Log: PR middle-end/44071 * cfglayout.c (fixup_reorder_chain): Allow asm goto to have no fallthru edge. * cfgcleanup.c (try_optimize_cfg): When in cfglayout mode optimizing away empty bb with no successors, move over its footer chain to fallthru predecessor. * cfgrtl.c (patch_jump_insn): Update also REG_LABEL_OPERAND. (rtl_split_edge): For asm goto call patch_jump_insn even if splitting fallthru edge. * c-c++-common/asmgoto-4.c: New test. * gcc.target/i386/pr44071.c: New test.
