Richard Osborne bfdc557c8a Expand unaligned 32 bit loads from an address which is a constant 
offset from a 32 bit aligned base as follows:

  ldw low, base[offset >> 2]
  ldw high, base[(offset >> 2) + 1]
  shr low_shifted, low, (offset & 0x3) * 8
  shl high_shifted, high, 32 - (offset & 0x3) * 8
  or result, low_shifted, high_shifted

Expand 32 bit loads / stores with 16 bit alignment into two 16 bit
loads / stores.

Richard Osborne 25b33cb035 Custom lower unaligned 32 bit stores and loads into libcalls. This is

Evan Cheng 84517443ca Let callers decide the sub-register index on the def operand of rematerialized instructions. 
Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.

Eli Friedman ebe66ab13b Don't restrict the set of instructions where we try to constant-fold the 
operands; it's possible to end up with a constant-foldable operand to 
most instructions, even those which can't trap.

Chris Lattner 55452c2bea fix an arm codegen bug (the same as PR4482 on ppc) where available_externally 
symbols were not getting stubs.  While I'm at it, add a big testcase for
stub generation to make sure I don't break anything.

Chris Lattner 7d1f9542c2 get the PPC stub temporary label from the mangler instead of 
using horrible string hacking.  This gives us a different label,
but it's just an assembler temporary, so the name doesn't matter.

Dan Gohman 92b969ba80 Fix the expansion of umax and smax in the case where one or more of 
the operands have pointer type, so that the resulting type matches
the original SCEV type, and so that unnecessary ptrtoints are
avoided in common cases.

Torok Edwin 8f2906a2e8 Introduce a pointertracking pass. 
For now this only computes the allocated size of the memory pointed to by a
pointer, and offset a pointer from allocated pointer.
The actual checkLimits part will come later, after another round of review.

Chris Lattner 8c9a96b966 Reapply my previous asmprinter changes now with more testing and two 
additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

Daniel Dunbar 966932ccb7 Revert r75610 (and r75620, which was blocking the revert), in the hopes of 
unbreaking llvm-gcc (on Darwin).

Chris Lattner 774f2a2d51 Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr" 
to symbols instead of doing it with "printSuffixedName".  This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.

This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.

Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

llvm-svn: 75610
 2009-07-14 06:04:35 +00:00
Chris Lattner f34815b32f Change the internal interface to makeNameProper to take a bool that 
indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.
