Anton Korobeynikov 6dbdfe2baa Factor out GVRequiresExtraLoad() from .h to .cpp 
llvm-svn: 32048
 2006-11-30 22:42:55 +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 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

 2006-11-28 01:28:00 +00:00
Andrew Lenharth e8c64aba11 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.

Reid Spencer 16eaffe595 When truncating to bool, it is necessary to & with 1 for all casts that 
can result in a bool. Previously PtrToInt, FPToUI and FPToSI were missing
this operation.

Reid Spencer 6c38f0bb07 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.

on non-x86-64 hosts.

Chris Lattner 2cca385fbb on ppc64, float arguments take 8-byte stack slots not 4-byte stack slots.

Chris Lattner 542dfd5510 Rewrite the branch selector to be correct in the face of large functions. 
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model.  This fixes assembler errors when compiling 403.gcc with
tail merging enabled.

Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion.  Only if branches need expansion are instructions rewritten
and created.  This should make branch select faster, and eliminates the
Bxx instructions from the .td file.

Chris Lattner 33fc1d45e5 add encoding for BCC, after finally wrestling strange ppc/tblgen endianness

Chris Lattner be9377a1e3 convert PPC::BCC to use the 'pred' operand instead of separate predicate 
value and CR reg #.  This requires swapping the order of these everywhere
that touches BCC and requires us to write custom matching logic for
PPCcondbranch :(

Evan Cheng 9e8093ae20 For unsigned 8-bit division. Use movzbw to set the lower 8 bits of AX while 
clearing the upper 8-bits instead of issuing two instructions. This also
eliminates the need to target the AH register which can be problematic on
x86-64.
