Subject: Fix failing overflow-1.c for avr
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=54eb90fe8a2645ce85266bede939eb0804c1bd80;p=gcc.git

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.dg/tree-ssa/overflow-1.c: Use __UINT32_TYPE__ for targets
	with sizeof(int) < 4.
