Chris Lattner b203355298 Split the valuetypes out of Target.td into ValueTypes.td 
llvm-svn: 26490
 2006-03-03 01:55:26 +00:00
Chris Lattner ad3c974a77 remove the read/write port/io intrinsics.

Chris Lattner 60a60f4b1e Implement CodeGen/PowerPC/or-addressing-mode.ll, which is also PR668.

Chris Lattner 27f5345b1f Compile this: 
void foo(float a, int *b) { *b = a; }

to this:

_foo:
        fctiwz f0, f1
        stfiwx f0, 0, r4
        blr

instead of this:

_foo:
        fctiwz f0, f1
        stfd f0, -8(r1)
        lwz r2, -4(r1)
        stw r2, 0(r4)
        blr

This implements CodeGen/PowerPC/stfiwx.ll, and also incidentally does the
right thing for GCC bugzilla 26505.

Chris Lattner f418435819 Use a target-specific dag-combine to implement CodeGen/PowerPC/fp-int-fp.ll. 
llvm-svn: 26445

Evan Cheng 990c3602bd Don't match x << 1 to LEAL. It's better to emit x + x. 
llvm-svn: 26429
 2006-02-28 21:13:57 +00:00
Chris Lattner b9f35f06bc Add a subtarget feature for the stfiwx instruction. I know the G5 has it, 
but I don't know what other PPC impls do.  If someone could update the proc
table, I would appreciate it :)

Chris Lattner ec185f7843 Don't print constant initializers, they may span lines now. 
llvm-svn: 26403

Jim Laskey 8f2c1021b4 Removed dependency on how operands are printed (want multi-line.)

Chris Lattner ab8164042a Implement bit propagation through sub nodes, this (re)implements 
PowerPC/div-2.ll

Chris Lattner a60751dd43 Check RHS simplification before LHS simplification to avoid infinitely looping 
on PowerPC/small-arguments.ll

llvm-svn: 26389
 2006-02-27 00:36:27 +00:00
Chris Lattner 27220f8958 Just like we use the RHS of an AND to simplify the LHS, use the LHS to 
simplify the RHS.  This allows for the elimination of many thousands of
ands from multisource, and compiles CodeGen/PowerPC/and-elim.ll:test2
into this:

_test2:
        srwi r2, r3, 1
        xori r3, r2, 40961
        blr

instead of this:

_test2:
        rlwinm r2, r3, 31, 17, 31
        xori r2, r2, 40961
        rlwinm r3, r2, 0, 16, 31
        blr

 2006-02-27 00:22:28 +00:00
Chris Lattner 118ddba929 Add a bunch of missed cases. Perhaps the most significant of which is that 
assertzext produces zero bits.

Evan Cheng 877ab55e06 ConstantPoolIndex is now the displacement portion of the address (rather 
than base).

llvm-svn: 26382
 2006-02-26 09:12:34 +00:00
Evan Cheng 75b8783aaf Fixed ConstantPoolIndex operand asm print bug. This fixed 2005-07-17-INT-To-FP 
and 2005-05-12-Int64ToFP.

llvm-svn: 26380
 2006-02-26 08:28:12 +00:00
Evan Cheng 77d86ff8fc * Cleaned up addressing mode matching code. 
* Cleaned up and tweaked LEA cost analysis code. Removed some hacks.
* Handle ADD $X, c to MOV32ri $X+c. These patterns cannot be autogen'd and
  they need to be matched before LEA.

llvm-svn: 26376
 2006-02-25 10:09:08 +00:00
Evan Cheng 1c557bfeb5 Updates. 
llvm-svn: 26375
 2006-02-25 10:04:07 +00:00
Evan Cheng 1fac3b3360 * Allow mul, shl nodes to be codegen'd as LEA (if appropriate). 
* Add patterns to handle GlobalAddress, ConstantPool, etc.
  MOV32ri to materialize these nodes in registers.
  ADD32ri to handle %reg + GA, etc.
  MOV32mi to handle store GA, etc. to memory.

llvm-svn: 26374
 2006-02-25 10:02:21 +00:00
Evan Cheng e4a8b74e4f ConstantPoolIndex is now the displacement field of addressing mode.

Evan Cheng 994700101e Added a common about the need for X86ISD::Wrapper. 
llvm-svn: 26372
 2006-02-25 09:55:19 +00:00
Evan Cheng ed169db8a5 Added an offset field to ConstantPoolSDNode.

Evan Cheng 42d5ac557c Fix an obvious bug exposed when we are doing 
ADD X, 4

Chris Lattner 7674d90fa1 Add memory printing support for PPC. Input memory operands now work with 
inline asms! :)

llvm-svn: 26365

Evan Cheng 0ed48fe601 PPC JIT relocation model should be DynamicNoPIC. 
llvm-svn: 26338
 2006-02-23 22:18:07 +00:00
Evan Cheng e0ed6ec13f - Clean up the lowering and selection code of ConstantPool, GlobalAddress, 
and ExternalSymbol.
- Use C++ code (rather than tblgen'd selection code) to match the above
  mentioned leaf nodes. Do not mutate and nodes and do not record the
  selection in CodeGenMap. These nodes should be safe to duplicate. This is
  a performance win.

llvm-svn: 26335
 2006-02-23 20:41:18 +00:00
Chris Lattner 1bad2546d0 Implement the PPC inline asm "L" modifier. This allows us to compile: 
long long test(long long X) {
  __asm__("foo %0 %L0 %1 %L1" : "=r"(X): "r"(X));
  return X;
}

to:
        foo r2 r3 r2 r3

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

llvm-svn: 26324
 2006-02-23 02:43:52 +00:00
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.

llvm-svn: 26323

Evan Cheng 7714a59d91 Missing .globl for weak / link-once .text symbols.

Chris Lattner 2e124af406 Don't return registers from register classes that aren't legal. 
llvm-svn: 26317
 2006-02-22 23:00:51 +00:00
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.

Evan Cheng 9e252e3bcf Added MMX, SSE1, and SSE2 vector instructions and some simple patterns. 
Fixed some existing bugs (wrong predicates, prefixes) at the same time.
