From 3c35efc322f7ff8d25b81cf9ebc01d0ec202bb89 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Fri, 25 Jan 2019 16:57:32 +0000 Subject: Fix output_constructor_bitfield handling of wide bitfields (PR89037) The testcase was failing because we were trying to access TREE_INT_CST_ELT (x, 1) of a 128-bit integer that was small enough to need only a single element. 2019-01-25 Richard Sandiford gcc/ PR middle-end/89037 * varasm.c (output_constructor_bitfield): Use wi::extract_uhwi instead of accessing TREE_INT_CST_ELT directly. gcc/testsuite/ PR middle-end/89037 * gcc.dg/pr89037.c: New test.
