Subject: [PATCH, CHKP] Restore transparent alias chains
Date: Fri, 20 Mar 2015 08:20:00 -0000	[thread overview]
Message-ID: <20150320082033.GG64546@msticlxl57.ims.intel.com> (raw)

Hi,

Identifiers read with input_identifier miss IDENTIFIER_TRANSPARENT_ALIAS bit.  We always expect it for instrumentation clones, thus restore it input_cgraph_1.  Bootstrapped and tested on x86_64-unknown-linux-gnu.  OK for trunk?

Thanks,
Ilya
