Revert patches that caused the problem. Evan, please investigate and reapply
when you've discovered the problem.

llvm-svn: 34399
2007-02-19 03:20:00 +00:00
Evan Cheng 9865be6d40 Added getReservedRegs().

2007-02-17 11:06:00 +00:00
Chris Lattner 1f7d60262e Fix ixaddrs as well, allowing ppc64 to compile to:
_test2:
        li r2, 0
        lis r3, 1
        std r2, 9024(r3)
        blr

instead of:

_test2:
        lis r2, 1
        li r3, 0
        ori r2, r2, 9024
        std r3, 0(r2)
        blr

This implements CodeGen/PowerPC/LargeAbsoluteAddr.ll:test2

Chris Lattner 4a9c0bb147 Compile test/CodeGen/PowerPC/LargeAbsoluteAddr.ll to:
_test:
        lis r2, 743
        li r3, 0
        stw r3, 32751(r2)
        blr

instead of:

_test:
        li r2, 0
        stw r2, 32751(48693248)
        blr

Implement support for ppc64 as well, allowing it to produce better code.

Evan Cheng 14edd1989b Use BitVector instead of vector<bool> which can be extremely slow.

Chris Lattner fed6f0e571 Switch LayoutInfo to be a DenseMap instead of an std::map. This speeds up
-load-vn -gcse by 2.3%.

llvm-svn: 34160

2007-02-10 20:18:06 +00:00
Chris Lattner e472f9c4dc eliminate the std::vector from StructLayout, allocating the elements immediately
after the StructLayout object in memory.  This marginally improves locality,
speeding up -load-vn -gcse by ~0.8%.

Chris Lattner 336e3962ff Change TargetData::getIndexedOffset interface to not require indices
in a vector.

llvm-svn: 34153

Evan Cheng 540f5e0d41 These vectors are frequently large. Use std::vector instead.

Bill Wendling e796b6de45 Fixed comments.
llvm-svn: 34040
2007-02-08 06:05:08 +00:00
Bill Wendling 2aa9a42f24 Moved the MachOWriter and ELFWriter out of the Target/* files. Placed the
definition of it into the CodeGen library. This is so that a backend doesn't
necessarily add in these writers if it doesn't use them (like in the lli
program).

llvm-svn: 34034
2007-02-08 01:39:44 +00:00
Bill Wendling 59889ae93f Added new method to add a "simple" code emitter. That is, to only add
the code emitter and not set variables.

llvm-svn: 34033
2007-02-08 01:38:33 +00:00
Bill Wendling 4e8ad36338 Dead files. Functionality has been taken over by the Add*Writer functions.

Evan Cheng b216ea1aa6 New entry.
llvm-svn: 34000
2007-02-07 09:22:15 +00:00
Evan Cheng 78c5a9422d In thumb mode, R3 is reserved, but it can be live in to the function. If
that is the case, whenever we use it as a scratch register, save it to R12
first and then restore it after the use.
This is a temporary and truly horrible workaround!

2007-02-07 09:17:36 +00:00
Evan Cheng 2ff0d3a2ab Update
llvm-svn: 33998
2007-02-07 08:37:57 +00:00
Evan Cheng b5519b5361 - If fp (r7) is used to reference stack objects, use [r, r] address mode.
- If there is a dynamic alloca, in the epilogue, restore the value of sp
  using r7 - offset.
- Other bug fixes.

2007-02-07 08:37:31 +00:00
Evan Cheng 12cf8ddaea eliminateFrameIndex() is even more complicated if frame ptr is used instead of SP when there are dynamic alloca's.
