--- Comment #1 from Joseph S. Myers <jsm28 at gcc dot gnu.org> --- Author: jsm28 Date: Mon Jun 20 22:58:20 2016 New Revision: 237622 URL: https://gcc.gnu.org/viewcvs?rev=237622&root=gcc&view=rev Log: Fix ICE on conditional expression between DFP and non-DFP float (PR c/71601). A conditional expression between DFP and non-DFP floating-point produces an ICE. This patch fixes this by making build_conditional_expr return early when c_common_type produces an error. Bootstrapped with no regressions on x86_64-pc-linux-gnu. PR c/71601 gcc/c: * c-typeck.c (build_conditional_expr): Return error_mark_node if c_common_type returns error_mark_node. gcc/testsuite: * gcc.dg/dfp/usual-arith-conv-bad-3.c: New test.
