Hello!
Attached patch enhances the testcase to also check for presence of MMX
registers on all 32bit x86 targets.
2014-05-17 Uros Bizjak <ubiz...@gmail.com>
* g++.dg/pr60969.C: Compile for all ilp32 x86 targets.
(dg-options): Add -mfpmath=387.
(dg-final): Check that no MMX registers are used.
Tested on x86-64-pc-linux-gnu {,-m32} and committed to mainline and 4.9 branch.
Uros.
