I tested this patch lifted from the bugzilla, and it does fix the problem for GCC 4.8. I'm also including the appropriate patch for GCC 4.9 (different due to the surrounding code being different). While there are other problems with SPE in GCC 4.9, I feel this patch is safe to apply. I have bootstraped the patch on a power7 running linux powerpc64 and there were no regressions between the unpatched gcc 4.8 and the build with the patch attached. I have verified that the bug is fixed when I build a SPE compiler with the patch attached for the GCC 4.8 patch. I have also bootstraped the GCC 4.9 patch on a power7 running linux powerpc64. As I write this message, I haven't done the make check regression test, but I will do that shortly. Are these patches ok to apply? I can apply just the 4.8 patch or both the 4.8 and 4.9 patches. 2013-12-12 Roland Stigge <sti...@antcom.de> Michael Meissner <meiss...@linux.vnet.ibm.com> * config/rs6000/rs6000.c (rs6000_legitimate_offset_address_p): Only check TFmode for SPE constants. Don't check TImode or TDmode.
