Chris Lattner fcee9b5568 fastcc functions that return double values now return them in xmm0 on x86-32.
This implements CodeGen/X86/fp-stack-ret.ll:test[23]

llvm-svn: 34592
2007-02-25 09:31:16 +00:00
Chris Lattner 2b8b520e53 verify that double is returned in XMM0 if the function is fastcc.

Chris Lattner 2fc0d70392 move LowerRET into the 'Return Value Calling Convention Implementation'
section of the file.

2007-02-25 09:12:39 +00:00
Chris Lattner ba474f58a4 make all Lower*CallTo implementations use LowerCallResult to handle their
result value stuff.  This eliminates a bunch of duplicated code and now
GetRetValueLocs is the sole place that decides where a value is returned.

llvm-svn: 34588
2007-02-25 09:10:05 +00:00
Chris Lattner 7802f3e2ea pass the calling convention into Lower*CallTo, instead of using ad-hoc flags.
llvm-svn: 34587
2007-02-25 09:06:15 +00:00
Chris Lattner 0cd9960fe7 factor a bunch of code out of LowerCCCCallTo into a new LowerCallResult
function.  This function now uses GetRetValueLocs to determine *where*
the result values are located and concerns itself with *how* to pull the
values out.

Chris Lattner 3c76309a5b move some code around, pass in calling conv, even though it is unused

Chris Lattner 387f464121 fold trivial token factor nodes. This allows us to compile
test/CodeGen/X86/fp-stack-ret.ll into:

        movl 4(%esp), %eax
        fldl (%eax)
        ret

instead of:

        subl $12, %esp
        movl 16(%esp), %eax
        movsd (%eax), %xmm0
        movsd %xmm0, (%esp)
        fldl (%esp)
        addl $12, %esp
        ret

by eliminating a token factor that blocked a check.

2007-02-25 08:23:01 +00:00
Chris Lattner dfda38f7dc simplify result value lowering by splitting the selection of *where* to return
registers out from the logic of *how* to return them.

This changes X86-64 to mark EAX live out when returning a 32-bit value,
where before it marked RAX liveout.

Reid Spencer 632ebdf8bd 1. Fix a bug in fromString for the <= 64bits case
2. Fix shl when shiftAmount == BitWidth.

Reid Spencer df6cf5ab71 1. Fix last bug in KnuthDiv. All divide tests pass up to 1024 bits now.
2. Clean up comments, style, coding standards, etc.
3. Simplify a constructor.

Extended testing revealed some additional bugs in shifting. I'll fix these
tomorrow.

2007-02-24 09:44:17 +00:00
Reid Spencer a5e0d200c9 1. Make internal functions take const arguments where they should, just
to be safe.
2. Make internal functions that return a carry/borrow return bool instead
   of uint64_t because the carry/borrow can only be in range [0,1].
3. Assert that the pointers to KnuthDiv are all different so that the
   result and operands can't overlap.
4. Add debug output to KnuthDiv function.
5. Fix a problem with KnuthDiv by separating the b's complement operation
   from the subtraction borrow operation. This fixes a wide range of
   division problems, but alas, not all of them.
