this test FAILs on 32-bit-default x86 configurations like i386-pc-solaris2.* and i686-pc-linux-gnu for the 64-bit multilib: FAIL: gcc.dg/profile-update-warning.c (test for warnings, line 7) FAIL: gcc.dg/profile-update-warning.c (test for excess errors) Excess errors: cc1: error: CPU you selected does not support x86-64 instruction set cc1: error: CPU you selected does not support x86-64 instruction set What happens here is that -m64 is added after -march=i386 -m32, causing the error above. This doesn't happen for 64-bit-default targets: in the 64-bit case there's just the -m32 from the testcase, for the 32-bit multilib just another -m32 is added, so the 32-bit case ist tested twice. Fixed like this, tested on i386-pc-solaris2.12 and x86_64-pc-linux-gnu, installed. Rainer 2016-09-28 Rainer Orth <r...@cebitec.uni-bielefeld.de> * gcc.dg/profile-update-warning.c: Restrict to ia32. (dg-options): Remove -m32.
