From 54eb90fe8a2645ce85266bede939eb0804c1bd80 Mon Sep 17 00:00:00 2001 From: Senthil Kumar Selvaraj Date: Tue, 21 Mar 2017 12:05:09 +0000 Subject: [PATCH] Fix failing overflow-1.c for avr The test assumes 32 bit ints, and expects a constant in the dump that is only valid for 32 bit ints. Fix by explicitly specifying __UINT32_TYPE__. gcc/testsuite/ 2017-03-21 Senthil Kumar Selvaraj * gcc.dg/tree-ssa/overflow-1.c: Use __UINT32_TYPE__ for targets with sizeof(int) < 4.
