Hello,
On SH a logical and with constants 0x or 0xFF can be done with the
respective zero-extension operations. The attached patch improves the
utilization of the zero-extension operations a little bit, resulting in
slightly better code.
Tested against rev 189081 with
make -k check RUNTESTFL
The fix for PR c++/52637 slightly broke the handling of local types in Ada.
The attached patch restores correct generation of debug info for them.
Tested on i586-suse-linux, applied on mainline and 4.7 branch.

This is a regression present on the mainline and 4.7 branch. The compiler

Hi DJ,
My concern is more about calling NEXT_INSN on a deleted insn. If
that's guaranteed to be "reliable", I'm OK with it.
So pick whichever solution is more future-proof and go for it :-)
OK, I have gone with the following. I have replaced NEXT_INSN with
next_nonnote_nondebug_insn, so
I'll try again.
On the other hand I am pretty sure that I have ISL unpacked in my source
