Subject: [patch] Fix gimple type checking errors on ppc
Date: Fri, 27 Jul 2007 11:00:00 -0000 [thread overview]
Message-ID: <20070727103731.GA14249@kam.mff.cuni.cz> (raw)
Hello,
build of gcc on ppc and ppc64 is failing for me with gimple type
checking messages. The problem is in the code generated by
rs6000_gimplify_va_arg, when TREE_TYPE (reg) is not compatible with
sizetype.
Bootstrapped & regtested on {ppc, ppc64}-linux.

* config/rs6000/rs6000.c (rs6000_gimplify_va_arg): Generate the
operands with compatible type.
