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%.

 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
 2007-02-10 19:33:15 +00:00
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 2ff4c973b1 isLowRegister() expects input is a physical register.

Evan Cheng ec4c67f0a7 If sp offset will be materialized in a register. Clear the offset field of str / ldr.

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!

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.

llvm-svn: 33997
 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. 
llvm-svn: 33975
 2007-02-07 02:44:23 +00:00
Evan Cheng ec13f826a2 Spill / restore should avoid modifying the condition register. 
llvm-svn: 33971
 2007-02-07 00:06:56 +00:00
Evan Cheng a974031ebd Select add FI, c correctly. 
llvm-svn: 33960
 2007-02-06 09:11:20 +00:00
Evan Cheng ea3308aef0 foldMemoryOperand() cannot fold tMOVrr sp into load / store in thumb mode. tLDRspi / tSTRspi cannot target / store high registers. 
llvm-svn: 33958
 2007-02-06 06:13:29 +00:00
Evan Cheng 2fc792f86b eliminateFrameIndex() bug when frame pointer is used as base register. 
llvm-svn: 33945
 2007-02-06 00:23:31 +00:00
Evan Cheng 650d0672f7 - Store val, [sp, c] must be selected to tSTRsp. 
- If c does not fit in the offset field, materialize sp + c into a register
  using tADDhirr.

Reid Spencer 92b50800f6 Although targets are not required to support integers > 64bits, TargetData 
must in order for backends that do want to support large integer types to be
able to function. Consequently, don't assert if the bitwidth > 64 bits
when computing the size and alignment. Instead, compute the size by rounding
up to the next even number of bytes for the size. Compute the alignment
as the same as the LongABIAlignment. These provide reasonable defaults
that the target can override.
