Chris Lattner 518b037620 completely eliminate the MOV16r0 'instruction'. The only 
interesting part of this is the divrem changes, which are
already tested by CodeGen/X86/divrem.ll.

Jakob Stoklund Olesen c7cfc94bcc Print out an informative comment for KILL instructions. 
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

Chris Lattner 0b4a59fc07 X86 should ignore implicit regs when lowering to MCInst also, 
no functionality change.

Chris Lattner f264f8a21c revert r84540, fixing build breakage I didn't see because of 
broken makefile deps :(

Jakob Stoklund Olesen dc9efe8078 Introduce the TargetInstrInfo::KILL machine instruction and get rid of the 
unused DECLARE instruction.

KILL is not yet used anywhere, it will replace TargetInstrInfo::IMPLICIT_DEF
in the places where IMPLICIT_DEF is just used to alter liveness of physical
registers.

Chris Lattner 17ec6b11d2 split random COFF asmprinter state out to X86COFFMachineModuleInfo.h. 
Make dllexport directives come out in determinstic order.

llvm-svn: 82381
 2009-09-20 06:45:52 +00:00
Chris Lattner 05f4039763 move FnStubs/GVSTubs/HiddenGVStub handling out of the X86 asmprinter 
and use MachineModuleInfoMachO instead.

llvm-svn: 82022
 2009-09-16 06:25:03 +00:00
Chris Lattner 1cbd3ded33 split MCInst printing out of the X86ATTInstPrinter 
class into its own X86ATTInstPrinter class.  The inst
printer now has just one dependence on the code generator
(TRI).

Chris Lattner 033d31165d merge the linux cpool/jtbl pic tests into pic.ll and convert to filecheck. 
Change the picbase symbol on non-darwin systems from ".Lllvm$4.$piclabel" to
".L4$pb".  The actual name doesn't matter and the darwin name is shorter.

llvm-svn: 81688
 2009-09-13 18:46:37 +00:00
Chris Lattner a602bebb61 devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden. 
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that
we only have one place that decides what to name bb labels.  Hopefully various
clients of printBasicBlockLabel can start using GetMBBSymbol instead.

llvm-svn: 81652

Chris Lattner a1378f3d89 factor MBB label lowering better 
llvm-svn: 81630
 2009-09-12 21:06:08 +00:00
Chris Lattner 6ccf7ed4be X86MCInstLower::Lower should only not emit anything to OutStreamer, 
this means that it can only lower one MachineInstr to one MCInst.  To
make this fly, we need to pull out handling of MO_GOT_ABSOLUTE_ADDRESS
(which generates an implicit label) out of X86MCInstLower.

llvm-svn: 81629
 2009-09-12 21:01:20 +00:00
Chris Lattner 5090e6c4a7 eliminate the "MBBLabel" MCOperand type, and just use a MCSymbol for 
MBB labels like everything else.

llvm-svn: 81628
 2009-09-12 20:45:03 +00:00
Chris Lattner 3172208823 split MachineInstr -> MCInst lowering into its own class (not 
being embedded into X86ATTAsmPrinter).  This still depends heavily
on X86ATTAsmPrinter, but this is a step in the right direction.

 2009-09-12 20:34:57 +00:00
Chris Lattner 42c1287b68 fix another GCC bootstrap problem, which manifested as things 
like:
foo.s:2412:non-relocatable subtraction expression, "_gomp_tls_key" minus "L1$pb"

Chris Lattner 19a9f42f20 switch HiddenGVStubs to be a DenseMap instead of a string map, mirroring FnStubs and GVStubs. 
llvm-svn: 81514
 2009-09-11 07:03:20 +00:00
Chris Lattner 446d589cad Fix a bug I introduced in FnStubs generation, switch GVStubs to be a 
densemap instead of StringMap to match FnStubs.

llvm-svn: 81513
 2009-09-11 06:59:18 +00:00
Chris Lattner 9a7edd6bba change FnStubs from being a StringMap<std::string> to being a much 
more efficient SmallPtrSet<MCSymbol*>.  This eliminates string
craziness and fixes CodeGen/X86/darwin-quote.ll with the new asmprinter.

Codegen is producing stubs in a nondeterminstic order, but it was doing
this before anyway.

llvm-svn: 81511
 2009-09-11 06:36:33 +00:00
Chris Lattner 30c44c053f printInstruction() no longer prints a \n after itself, do it 
for the two instruction MOVPC32r sequence.

llvm-svn: 81509
 2009-09-11 05:59:55 +00:00
Chris Lattner 35ed98aaef reimplement X86ATTAsmPrinter::GetGlobalAddressSymbol in terms of 
Mangler::getNameWithPrefix.  In addition to avoiding some over
quoting, this also is more efficient because it uses smallvector
instead of std::string thrashing.

llvm-svn: 81508
 2009-09-11 05:58:44 +00:00
Chris Lattner 1051efc339 convert X86ATTAsmPrinter::GetExternalSymbolSymbol to use SmallString 
instead of std::string and Mangler.

llvm-svn: 81503
 2009-09-11 04:36:43 +00:00
Chris Lattner 482c5df56d rearrange some code, export a SmallString version of DecorateCygMingName.

 2009-09-11 04:28:13 +00:00
Chris Lattner 321bc99a74 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

llvm-svn: 81396
 2009-09-09 23:14:36 +00:00
Chris Lattner d9e12345af add a gross hack to get "SrcLine" comments to show up with the 
new asmprinter.  Differently gross hack coming next.

llvm-svn: 81379
 2009-09-09 20:45:42 +00:00
Chris Lattner 716a8c92d0 hoist the call to processDebugLoc out of the generated 
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

 2009-09-09 20:34:59 +00:00
Chris Lattner f2fefedcf8 make sure to send external symbols through the mangler, 
this fixes mingw-alloca.ll with the new asmprinter.

 2009-09-09 00:23:32 +00:00
Chris Lattner c5a95c5aad add support for @PLT and friends on external symbols, fixes 
x86-64-pic-11.ll with the new asmprinter.

llvm-svn: 81199
 2009-09-08 06:25:12 +00:00
Chris Lattner 31d1810b16 add a bunch more evil lowering code to work around various :subreg32 modifiers 
in the .td files.  This gets us down to 18 failures in codegen/x86 with the
new asmprinter.

llvm-svn: 81198
 2009-09-08 06:19:15 +00:00
Chris Lattner 520a7f9250 ADd support for "lowering" the X86::MOVZX16rr8/X86::MOVZX16rm8 
subreg32 modifiers.

llvm-svn: 81196
 2009-09-08 06:03:07 +00:00
Chris Lattner 8280e58545 add a hack to lower MOV16r0 to MOV32r0 in MCInstLower, eliminating 
the problem with subreg32 modifiers.  This gets all of Olden working
with the new asmprinter.

Chris Lattner 51a0712538 don't call getOffset() on jump tables, this fixes three failing olden benchmarks 
with the new asmprinter.

llvm-svn: 80906
 2009-09-03 07:36:42 +00:00
Chris Lattner c7b00730ad Implement support for X86II::MO_GOT_ABSOLUTE_ADDRESS. We get very 
different formatting from the old asmprinter, but it should be 
semantically the same.  We used to get:

	popl	%eax
	addl	$_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$6.$piclabel], %eax
...

Now we get:

	popl	%eax
.Lpicbaseref6:
	addl	$(_GLOBAL_OFFSET_TABLE_ + (.Lpicbaseref6 - .Lllvm$6.$piclabel)), %eax
...

Chris Lattner 954b9cd41f merge globaladdress symbol processing stuff into other stuff. Now 
all global variable operand flag processing stuff is shared between
different operand types.

llvm-svn: 80886
 2009-09-03 05:06:07 +00:00
Chris Lattner 6370d5606c Split the "operand -> symbol" logic from the "get offset and other munging 
from operand" logic.  GlobalAddress still todo.

llvm-svn: 80884
 2009-09-03 04:56:20 +00:00
Chris Lattner 5daf61910e implement lowering support for constant pool index operands, this gets a bunch more
