Hi there.
I recently came across a nice micro-optimization to permutate bytes
within a dword. On x86 all 24 combinations can be done using a maximum
of 3 instructions (bswap, rotate32 and rotate16).
I'd like to give it a try and write an optimization pass that detects
such dword permutations

Successfully bootstrapped and installed gcc 4.3.1, using mingw32 (msys)
under WinXP.
config.guess is having problems though.
$ gcc -v
Using built-in specs.
Target: mingw32
Configured with: ../gcc-4.3.1/configure --with-gcc --build=mingw32
--prefix=/mingw --with-mpfd=/usrlocal --with-gmp=/usrloc
Okay, i isolated the problem (we are folding based on the wrong type
for constants, so we have a case where 1 << 63 becomes 0 instead of a
very large value).
Working on a patch now.

I wonder, could/should this also become a
