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.

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.

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?

Anton Korobeynikov 75e8a144d4 Regenerate
llvm-svn: 33599
2007-01-28 13:37:39 +00:00
Anton Korobeynikov 037c867b54 Propagate changes from my local tree. This patch includes:
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.
