Bug #: 57144
Summary: [4.9 regression] mpfr miscompiled after r198413
Classification: Unclassified
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Keywords: build
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: schwab@linux-m68k.org
CC: law@gcc.gnu.org
Depends on: 57124
Target: ia64-*-*
r198413 is causing miscompilation of mpfr-2.4.2 on ia64, seen by a lot of
failures in its testsuite, some are looping infinitely. This makes it
impossible to bootstrap with an in-tree mpfr, because the fortran compiler
hangs while calling mpfr_log10 from gfc_arith_init_1.
The patch in <http://permalink.gmane.org/gmane.comp.gcc.patches/285076> does
not help.
