movl 8(%esp), %eax
movl 12(%esp), %edx
bswap %eax
bswap %edx

Implement signedness caching for values, value lists, constants and
...
constant lists. This is just an internal change to the parser in
preparation for some backwards compatibility code that is to follow.
This will allow things like "uint 4000000000" to retain the unsignedness
of the integer constant as the value moves through the parser. In the
future, all integer types will be signless but parsing "uint" and friends
will be retained for backwards compatibility.

Preliminary support for inline asm in the cbe. The target specific ugliness
...
is still in Writer, but issolated to a single function. This might be split
into something in each target directory. This is sufficient to get through
archie and an strcpy impl on linux-x86.
Module level asm is not handled.

For PR950:
...
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.
