Richard Osborne d7b887410d Remove xs1a subtarget. xs1a is a preproduction device used in 
early development boards which is no longer supported in the
XMOS toolchain.

Duncan Sands 9ed7b16bf3 Introduce and use convenience methods for getting pointer types 
where the element is of a basic builtin type.  For example, to get
an i8* use getInt8PtrTy.

Jeffrey Yasskin e97fe329e9 Fix http://llvm.org/PR5116 by rolling back r60822. This passes `make unittests 
check-lit` on both x86-64 Linux and x86-32 Darwin.

This code is not  yet enabled.

Devang Patel d859d86538 Existence of a compile unit for input source file is a good indicator to check debug info's presence in a module.

Devang Patel 1c9eef72b4 If subprogram die is not available then construct new one. 
This can happen if debug info is processed lazily.

Devang Patel 4c420eca41 Adjust context for the global variables that are not at file scope, e.g. 
void foo() { static int bar = 42; }
Here, foo's DIE is parent of bar's DIE.

Jim Grosbach 2dfb5da6bb In Thumb1, the register scavenger is not always able to use an emergency 
spill slot. When frame references are via the frame pointer, they will be
negative, but Thumb1 load/store instructions only allow positive immediate
offsets. Instead, Thumb1 will spill to R12.

Torok Edwin c5b8846891 Don't treat malloc calls with non-matching prototype as malloc. 
Fixes second part of PR5130, miscompilation in FreeBSD kernel, where malloc takes 3 params,
and *does* initialize memory.

llvm-svn: 83310
 2009-10-05 16:31:55 +00:00
Dan Gohman 2728569a38 Remove explicit enum integer values. They don't appear to be needed, and 
they make it less convenient to add new entries.

llvm-svn: 83308
 2009-10-05 15:52:08 +00:00
Dan Gohman 774149a878 Add RIP to GR64_NOREX. This fixed a MachineVerifier error when RIP 
is used in an operand which requires GR64_NOREX.

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

Chris Lattner 463716d559 instcombine shouldn't delete all null checks for mallocs. 
This fixes PR5130.

Chris Lattner ff00c3562a stop MachineFunctionPass from claiming that it preserves LoopDependence info, 
which causes dependence info to be linked into lli.

Chris Lattner cb08fb7b83 remove llvm-db: it is completely broken and if anyone wants to do a debugger, 
they should not base it on llvm-db (which not following almost any "best practices").

Owen Anderson b5049bebb3 Do away with the strange use of BitVectors in SSI, and just use normal sets. This makes the code much more C++/LLVM-ish.

llvm-svn: 83283
 2009-10-04 17:52:13 +00:00
Owen Anderson a62bf10651 SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction. 
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.

Benjamin Kramer f01ee30328 MingW build fixes 
- MingW needs -lpsapi (in ${LIBS}) linked after -lLLVMSystem.
  Noticed by Ronald Pijnacker!

- Some parts of the System library must be build with exceptions on windows.
  Based on a patch by Jay Foad!
