Evan Cheng 1f342c2884 PIC related bug fixes.
1. Various asm printer bug.
2. Lowering bug. Now TargetGlobalAddress is wrapped in X86ISD::TGAWrapper.

Evan Cheng 7eabbfd618 X86 codegen tweak to use lea in another case:
Suppose base == %eax and it has multiple uses, then instead of
  movl %eax, %ecx
  addl $8, %ecx
use
  leal 8(%eax), %ecx.

Chris Lattner e5521db5bc Fix Regression/Transforms/LoopUnswitch/2006-02-22-UnswitchCrash.ll, which
caused SPASS to fail building last night.

We can't trivially unswitch a loop if the exit block has phi nodes in it,
because we don't know which predecessor to use.

2006-02-22 23:00:51 +00:00
Chris Lattner 6f87d18be9 Change a whole bunch of code to be built around RegsForValue instead of
a single register number.  This fully implements promotion for inline asms,
expand is close but not quite right yet.

Evan Cheng 73136dfecc - Added option -relocation-model to set relocation model. Valid values include static, pic,
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.

Chris Lattner 747cf60696 The HasNoV9 hack isn't needed here, now that tblgen knows that CustomDAGSchedInserter
instructions are expensive.

llvm-svn: 26298
2006-02-21 18:04:32 +00:00
Evan Cheng d57203c0a1 Added separate alias instructions for SSE logical ops that operate on non-packed types.

2006-02-20 19:58:27 +00:00
Chris Lattner 301f45cf6f Fix a problem Nate and Duraid reported where simplifying nodes can cause
them to get ressurected, in which case, deleting the undead nodes is
unfriendly.

llvm-svn: 26291
2006-02-20 06:51:04 +00:00
Chris Lattner 486d1bc5ed Fix a problem on itanium with memset. The value to set has been promoted to
i64 before this code, so zero_ext doesn't work.

2006-02-18 03:20:33 +00:00
Nate Begeman 983ca89714 Add a fold for add that exchanges it with a constant shift if possible, so
that the shift may be more easily folded into other operations.

llvm-svn: 26286

2006-02-18 02:42:34 +00:00
Nate Begeman abac61603f Add checks to make sure we don't create bogus extend nodes, and fix a bug
where we were doing exactly that which was causing failures on x86 and
alpha.
