Subject: [Bug rtl-optimization/42889] [4.5 Regression] "-fcompare-debug failure (length)" with "-O1 -fgcse"
Date: Thu, 28 Jan 2010 22:09:00 -0000	[thread overview]
Message-ID: <20100128220928.11200.qmail@sourceware.org> (raw)
In-Reply-To: <bug-42889-14164@http.gcc.gnu.org/bugzilla/>



------- Comment #18 from jakub at gcc dot gnu dot org  2010-01-28 22:09 -------
Those need to be analyzed, perhaps some will need a similar change, many others
don't need any change, as they can't be called for DEBUG_INSNs.  E.g.
DEBUG_INSN isn't changing control flow, so any changes to it won't add/remove
basic blocks, etc.
But I fail to see why we'd need to solve all at once.

This patch has been successfully bootstrapped/regtested on x86_64-linux and
i686-linux BTW.
