Subject: Fix verify_type ICE with -fshort-enum
Date: Thu, 11 Jun 2015 21:49:00 -0000	[thread overview]
Message-ID: <20150611214743.GA59435@kam.mff.cuni.cz> (raw)

Hi,
gcc.c-torture/execute/930408-1.c currently ICE on -fshort-enum target(s) because
TYPE_PACKED is not consistently set among type variants.

Bootstrapped/regtested ppc64le-linux, OK?
Honza

	PR middle-end/66325
	* c-decl.c (start_enum): Set TYPE_PACKED consistently among type variants.
