Subject: [pph] Do not emit PCH if generating PPH (issue4591061)
Date: Thu, 09 Jun 2011 18:55:00 -0000	[thread overview]
Message-ID: <20110609184955.794601DA1CD@topo.tor.corp.google.com> (raw)


We were trying to generate PCH and PPH information at the same time.
We never noticed because PPH is generated after PCH, so we were just
clobbering over the previous dump.

Found it by accident while debugging a GC ICE.  This should make
testing slightly faster.

Committed to the branch.



	* lang-specs.h (@c++-header): Do not emit PCH if any -fpph flag is
	present.
