llvm-svn: 32047
 2006-11-30 22:07:00 +00:00
Evan Cheng ae1cd75af7 - Use a different wrapper node for RIP-relative GV, etc. 
- Proper support for both small static and PIC modes under X86-64
- Some (non-optimal) support for medium modes.

Chris Lattner aeddf5f077 new bswap idiom 
llvm-svn: 32012
 2006-11-29 07:21:08 +00:00
Chris Lattner 960acb008b implement cast.ll:test35. With this, we recognize: 
unsigned short swp(unsigned short a) {
       return ((a & 0xff00) >> 8 | (a & 0x00ff) << 8);
}

as an idiom for bswap.

Chris Lattner d747f015ff Teach instcombine to turn trunc(srl x, c) -> srl (trunc(x), c) when safe. 
This implements InstCombine/cast.ll:test34.  It fires hundreds of times on
176.gcc.

Chris Lattner 38084725a2 Upgrade the ugly darwin 64-bit bswap idiom (bswap %eax / bswap %edx / 
xchgl %eax, %edx) to llvm.bswap.i64.  This compiles:

long long test2(long long A) {
  return _OSSwapInt64(A);
}

to:

_test2:
        movl 8(%esp), %eax
        movl 4(%esp), %edx
        bswapl %eax
        bswapl %edx
        ret

instead of:

_test2:
        movl 8(%esp), %edx
        movl 4(%esp), %eax
        bswap   %eax
        bswap   %edx
        xchgl   %eax, %edx
        ret

GCC manages (with -fomit-frame-pointer) the uglier:

_test2:
        subl    $4, %esp
        movl    8(%esp), %eax
        movl    12(%esp), %edx
        bswap   %eax
        bswap   %edx
        xchgl   %eax, %edx
        addl    $4, %esp
        ret

Chris Lattner 0fc6ae0c3d Trivially lower 'bswap $0' into llvm.bswap. This fixes hexxagon with the 
JIT on darwin/x86, which has htonl implemented as inline asm.

Chris Lattner 90f4238c38 add a hook to allow targets to hack on inline asms to lower them to llvm 
when they want to.
