--- Comment #40 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- (In reply to Oleg Endo from comment #39) > Can we close this PR as fixed? I've got ============================================================================ Testsuite summary for MPFR 3.1.3 ============================================================================ # TOTAL: 160 # PASS: 159 # SKIP: 1 # XFAIL: 0 # FAIL: 0 # XPASS: 0 # ERROR: 0 ============================================================================ with my 4.9 native compiler built with 4.9 cross compiler for svn gcc-4_9-branch. I hope that miscompilation for mpfr is gone for bootstrapped 4.9 compiler and it fixes the original gcc issue too. Matthias, Adrian, what about the original error?
