Evan Cheng a2ce665f60 Another nasty coalescer bug (is there another kind): 
After coalescing reg1027's def and kill are both at the same point:
 %reg1027,0.000000e+00 = [56,814:0)  0@70-(814)

bb5:
60   %reg1027<def> = t2MOVr %reg1027, 14, %reg0, %reg0
68   %reg1027<def> = t2LDRi12 %reg1027<kill>, 8, 14, %reg0
76   t2CMPzri %reg1038<kill,undef>, 0, 14, %reg0, %CPSR<imp-def>
84   %reg1027<def> = t2MOVr %reg1027, 14, %reg0, %reg0
96   t2Bcc mbb<bb5,0x2030910>, 1, %CPSR<kill>

Do not remove the kill marker on t2LDRi12.

Bruno Cardoso Lopes 2b1dc9a783 - Remove custom handling of jumptables by the elf writter (this was 
a dirty hack and isn't need anymore since the last x86 code emitter patch)
- Add a target-dependent modifier to addend calculation
- Use R_X86_64_32S relocation for X86::reloc_absolute_word_sext
- Use getELFSectionFlags whenever possible
- fix getTextSection to use TLOF and emit the right text section 
- Handle global emission for static ctors, dtors and Type::PointerTyID
- Some minor fixes

Andreas Bolka d3a44b52c6 Restrict LDA to GEPs with the same pointer offset. 
We can not simply apply ZIV testing to the pointer offsets, as this
would incorrectly return independence for e.g. (GEP x,0,i; GEP x,1,-i).

llvm-svn: 78150
 2009-08-05 03:45:09 +00:00
Zhongxing Xu fe97165587 If the UnaryOperator has non-location type, use its type to create the 
constant value. If the UnaryOperator has location type, create the
constant with int type and pointer width.

This fixes the bug that all pointer increments 'p++' evaluated to Unknown.

Dan Gohman f9bbcd1afd Major calling convention code refactoring. 
Instead of awkwardly encoding calling-convention information with ISD::CALL,
ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering
provides three virtual functions for targets to override:
LowerFormalArguments, LowerCall, and LowerRet, which replace the custom
lowering done on the special nodes. They provide the same information, but
in a more immediately usable format.

This also reworks much of the target-independent tail call logic. The
decision of whether or not to perform a tail call is now cleanly split
between target-independent portions, and the target dependent portion
in IsEligibleForTailCallOptimization.

This also synchronizes all in-tree targets, to help enable future
refactoring and feature work.

Dan Gohman cbf1e16ad9 Remove an unnecessary flush in the CppBackend's output. 
llvm-svn: 78138
 2009-08-05 01:06:38 +00:00
Dan Gohman c6b5e8a5c5 Don't flush the raw_ostream between each MachineFunction. These flush 
calls were originally put in place because errs() at one time was
not unbuffered, and these print routines are commonly used with errs()
for debugging. However, errs() is now properly unbuffered, so the
flush calls are no longer needed. This significantly reduces the
number of write(2) calls for regular asm printing when there are many
small functions.

Bob Wilson 20f79e321e Change DAG nodes for Neon VLD2/3/4 operations to return multiple results. 
Get rid of yesterday's code to fix the register usage during isel.
Select the new DAG nodes to machine instructions.  The new pre-alloc pass
to choose adjacent registers for these results is not done, so the
results of this will generally not assemble yet.
