I am looking at implementing a GCC optimization pass based on constant
propagation into a switch statement.
Given:
if (expr)
s = 1;
codeX; (code that allows definition of s to propogate through)
switch (s) {
How about finding the single-entry/single exit region that dominates
the switch and post-dominates the s assignment. You can then examine
if s is modified in the region.

Exactly one year after the last major GCC release has been announced,
celebrating the 26th anniversary of the GNU Compiler Collection,
the GCC development team announces a new major GCC release, 4.8.0.
GCC 4.8.0 is a major release containing substantial new
functionality not available in GCC 4.7.x
Status
==
GCC 4.8.0 has been released, the branch is now open again under the usual
release branch rules (regression fixes and documentation fixes only).
The next release, 4.8.1, should be released in about two or three months
from now, unless something very urgent forces us to release earlier

Snapshot gcc-4.6-20130322 is now available on
ftp://gcc.gnu.org/pub/gcc/snapshots/4.6-20130322/
and on various mirrors, see http://gcc.gnu.org/mirrors.html for details.
This snapshot has been generated from the GCC 4.6 SVN branch
with the following options: svn://gcc.gnu.org/svn/gcc/branches
Does gcc 4.8 include the changes to decltype specified in N3276
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/n3276.pdf)? If
not, can we expect these for 4.8.1?
Thanks,
Joe Gottman
