Subject: [Bug tree-optimization/45144] SRA optimization issue of bit-field
Date: Fri, 30 Jul 2010 17:10:00 -0000	[thread overview]
Message-ID: <20100730170954.29572.qmail@sourceware.org> (raw)
In-Reply-To: <bug-45144-11162@http.gcc.gnu.org/bugzilla/>



------- Comment #1 from jakub at gcc dot gnu dot org  2010-07-30 17:09 -------
The solution IMNSHO is to detect adjacent bitfield operations that can be
handled together and lower bitfield ops still at the tree level, though soon
before expansion, rather than disabling SRA for bitfields.
