Message207554
After lots of fiddling, I can tell you what's wrong with the macro: apparently it's a compiler bug, visible at -O2 and disappearing at -O1.
Assembly output is attached, unfortunately, I'm no ppc64 expert, so I can't immediately tell what exactly went wrong.
In any case, the first half of the bug (missing check for HAVE_LETOH64) which triggered the second half still seems valid.
I think it's not feasible to upgrade the compiler on RHEL 6.5 (unless someone with a subscription wants to have a go), but fixing the first part should avoid the compiler bug altogether. |
