Jim Laskey 14059d958a Fix for PR1224. 
llvm-svn: 34610
 2007-02-25 21:43:59 +00:00
Chris Lattner 76ac8f82bd Rework GlobalValue::removeDeadConstantUsers to always remove dead constant 
exprs hanging off a global, even if the global is not otherwise dead.  This
requires some tricky iterator gymnastics.

This implements Transforms/GlobalOpt/constantexpr-dangle.ll by deleting a
constantexpr that made it appear that the address of the function was taken.

Reid Spencer a41e93be3d 1. Provide more detail in file comment. 
2. Move comments for methods to .h file, delete them in .cpp file.
3. All places that were doing manual clear of high order bits now call the
   clearUnusedBits() method in order to not depend on undefined behavior
   of the >> operator when the number of bits shifted equals the word size.
4. Reduced # of loc by using the new result of clearUnusedBits() method.
5. Simplified logic (decreased indentation) in a few places.
6. Added code comments to larger functions that needed them.
7. Added FIXME notes about weak implementations of things (e.g. bit-by-bit
   shift right is sub-optimal).

Chris Lattner 84ab9a556c one important bugfix: PPC32 didn't have both elf and macho support for 
external symbols and global addresses.  Add the missing ones.

one important workaround: PPCISD::CALL is matched by both PPCcall_ELF
and PPCcall_Macho, disable the _ELF patterns for now.

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]

 2007-02-25 09:14:25 +00:00
Chris Lattner 2fc0d70392 move LowerRET into the 'Return Value Calling Convention Implementation' 
section of the file.

llvm-svn: 34589
 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.

llvm-svn: 34586
 2007-02-25 08:59:22 +00:00
Chris Lattner 3c76309a5b move some code around, pass in calling conv, even though it is unused 
llvm-svn: 34585
 2007-02-25 08:29:00 +00:00
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.

llvm-svn: 34584
 2007-02-25 08:24:27 +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.

tomorrow.

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.

Evan Cheng 84a041eb98 ELF / PIC requires GOT be in the EBX register during calls via PLT GOT pointer. 
Add implicit uses of EBX to calls to ensure liveintervalanalysis does not treat
the GOT in EBX move as dead upon definition.
This should fix PR1207.

2. Change 0 initialization of union to larger component so all is zeroed.
3. Fix the borrow logic in subtraction so it works for > 128 bits.
4. Rewrite fromString to use a simpler but correct algorithm and also to
   not set the bit width contrary to the user's request.
5. Optimize toString a bit by making it only do one Knuth divide per
   iteration instead of two.

With these changes, all arithmetic passes (verified by pari/GP) up to
1024 bits except for certain division cases.

Reid Spencer fb77b2ba13 First version that can process arith.cpp test case up to 1024 bits: 
1. Ensure pVal is set to 0 in each constructor.
2. Fix roundToDouble to make correct calculations and not read beyond the
   end of allocated memory.
3. Implement Knuth's "classical algorithm" for division from scratch and
   eliminate buffer overflows and uninitialized mememory reads. Document
   it properly too.
4. Implement a wrapper function for KnuthDiv which handles the 64-bit to
   32-bit conversion and back. It also implement short division for the
   n == 1 case that Knuth's algorithm can't handle.
5. Simplify the logic of udiv and urem a little, make them exit early, and
   have them use the "divide" wrapper function to perform the division
   or remainder operation.
6. Move the toString function to the end of the file, closer to where
   the division functions are located.

Note: division is still broken for some > 64 bit values, but at least it
      doesn't crash any more.

Reid Spencer 421bad0dc5 Implement support for non-standard integer bit widths of any size. The 
rules alignment is to pick the alignment that corresponds to the smallest
specified alignment that is larger than the bit width of the type or the
largest specified integer alignment if none are larger than the bitwidth
of the type. For the byte size, the size returned is the next larger
multiple of the alignment for that type (using the above rule). This patch
also changes bit widths from "short" to "uint32_t" to ensure there are
enough bits to specify any bit width that LLVM can handle (currently 2^23);
16-bits isn't enough.

Reid Spencer 6e4c277858 For PR1194: 
The bcreader counts on "primitive" types being inserted before they are
referenced in other types. With recent changes to the bcwriter, this fact
became exposed since IntegerType is no longer "primitive". We can no longer
count on all IntegerTypes being inserted early. This patch modifies
getOrCreateTypeSlot to insert any sub-type that can't possibly recurse
before we create the slot for the type. This has the benefit of reducing
the number of OpaqueType objects the reader needs to deal with.
