--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> --- Created attachment 35016 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35016&action=edit Test case for nettle md4 test failure. The attached test case reduced from Nettle 3.0 test 7 in testsuite/md4-test.c reproduces the suspected gcc 5.0 incorrect code generation on ppc64le. Compile with -O3 and run and observe a SIGABRT.
