--- Comment #13 from sudi at gcc dot gnu.org --- Author: sudi Date: Thu Mar 29 09:19:45 2018 New Revision: 258948 URL: https://gcc.gnu.org/viewcvs?rev=258948&root=gcc&view=rev Log: [ARM][PR target/84826] Fix ICE in extract_insn, at recog.c:2304 on arm-linux-gnueabihf This patch backports r258777 and r258805 to gcc-7-branch and gcc-6-branch. The same ICE occurs in both the branches with -fstack-check. Thus the test case directive has been changed.
