MPFR_RNDx was introduced in MPFR 3.0.0. Since the minimal version that gcc checks for is 2.4.0, this leads to a build failure.The fix is straightforward. Tested on x86_64-pc-linux-gnu. Committed to trunk as obvious. * gimple-ssa-sprintf.c (format_floating): Change MPFR_RNDx to GMP_RNDx for compatibility.
This was changed once before for this reason (in r240350). I forgot all about it and put it back in my latest patch for some reason. I don't remember why exactly but I suspect I might have been trying to overcome some MPFR oddity. It might help to #undef the MPFR_RNDx macros after including <mpfr.h> to avoid this in the future. In any event, thanks for the fix. Martin
