Evan Cheng e43ca022bf In thumb mode, round up stack frame size to multiple of 4 since add/sub 
sp, imm instructions implicitly multiply the offset by 4.

Evan Cheng 1cd3c0efb8 Change the operand orders to t_addrmode_s* to make it easier to morph 
instructions that use these address modes to instructions that use
t_addrmode_sp.

Evan Cheng 7fa6964dc2 - In thumb mode, if size of MachineFunction is >= 2048, force LR to be 
spilled (if it is not already).
- If LR is spilled, use BL to implement far jumps. LR is not used as a GPR
  in thumb mode so it can be clobbered if it is properly spilled / restored
  in prologue / epilogue.
- If LR is force spilled but no far jump has been emitted, try undo'ing the
  spill by:
  push lr -> delete
  pop pc -> bx lr

Chris Lattner d27f95e08d add initial support for handling inline asms with multiple constraints. 
This doesn't do the "right thing" but will probably work in most cases.

This implements CodeGen/PowerPC/2007-01-29-lbrx-asm.ll.

 2007-01-29 23:20:22 +00:00
Devang Patel 1c3633e461 - Undo previous check-in (i.e. Do not export TimingInfo class through 
PassManagers.h).

- Add StopPassTimer() and StartPassTimer() to expose TimingInfo to
CallGraphPassManager

- Use these two APIs in CalLgraphPassManager to measure timings.

address nodes.

Nate Begeman e3b09fbbb0 We'd still like to register allocate r2 on darwin before the callee-save

Reid Spencer e87c917a69 For PR1142: 
When an unresolved definition is found, check to see if it is only unresolved
because the csretcc was upgraded to the sret param attribute. Such changes
change the function type and lead to unresolved definitions. In such cases, just
cast the function to the type expected by the CallInst. That is, cast to the
version of the function that has the sret param attribute.

Reid Spencer 1e960cd4fd Implement use of new IntrinsicLowering interface. 
llvm-svn: 33619
 2007-01-29 17:51:02 +00:00
Reid Spencer d7035b654b Use TargetData to obtain the correct size of the "size_t" argument for 
functions like memcpy, memmove and memset. Ensure only one prototype is
used for these functions and that it matches the system definition by
using the appropriate type for the size argument.

Nick Lewycky 56639800c9 Simplify names of lattice values. SGTUNE becomes SGT, for example. 
Fix initializeConstant, now initializeInt. Fixes major performance
bottleneck.

X == Y || X->DominatedBy(Y) is redundant. Remove the X == Y part.

Fix crasher in makeEqual where getOrInsertNode would add a new constant,
producing an NE relationship between the two members we're trying to make
equal. This now allows us to mark more BBs as unreachable.

Reid Spencer c7765617d2 For PR1138: 
Force memcpy to be the 32-bit variant. Since this is only used with
CBE and lli which both target 32-bit machines, this should be okay.

Anton Korobeynikov 06f7d4bec7 Arguments are counting from 1. not from 0. Maybe we should change 
numbering somehow? E.g. make return argument the last?
