Chris Lattner 697150ec0c don't copy TargetLowering. 
llvm-svn: 77293
 2009-07-28 03:05:40 +00:00
David Goodwin 57b51d9f82 ORN does not require (and can not have) the ".w" suffix. "Orthogonality" is a dirty word at ARM.

 2009-07-27 23:34:12 +00:00
Daniel Dunbar 52d03b252e llvm-mc: Move AsmLexer::getCurStrVal to StringRef based API. 
- My DFS traversal of LLVM is, at least for now, nearly complete! :)

llvm-svn: 77258
 2009-07-27 21:49:56 +00:00
Chris Lattner 9d0e762c81 hoist MCContext/MCStreamer up to AsmPrinter since we're going to start creating 
MCSections soon instead of Section for all targets, and we need something to
own them.

llvm-svn: 77252
 2009-07-27 21:28:04 +00:00
Owen Anderson 69c464dec4 Move ConstantFP construction back to the 2.5-ish API. 
llvm-svn: 77247
 2009-07-27 20:59:43 +00:00
David Goodwin e5b969f6a6 Remove TPat. No patterns depend on just isThumb(). Must use either T1Pat (isThumb1Only()) or T2Pat (is Thumb2). 
llvm-svn: 77242
 2009-07-27 19:59:26 +00:00
Chris Lattner e7cb8f7987 Sink getSectionPrefixForUniqueGlobal down into the TAI 
implementations that need it, rearrange ELFTAI.

llvm-svn: 77236
 2009-07-27 19:14:14 +00:00
Chris Lattner 375a01c34a remove dead code. 
llvm-svn: 77233
 2009-07-27 19:00:33 +00:00
Evan Cheng 38b7eee164 More DCE. 
llvm-svn: 77231
 2009-07-27 18:48:45 +00:00
Evan Cheng 0e075e2429 convertToThreeAddress can't handle Thumb2 instructions (which don't have same address mode as ARM instructions). 
llvm-svn: 77230
 2009-07-27 18:44:00 +00:00
Evan Cheng 18688f431d Get rid of more dead code. 
llvm-svn: 77227
 2009-07-27 18:38:54 +00:00
Evan Cheng 239ed4b343 Cosmetic change. 
llvm-svn: 77222
 2009-07-27 18:31:40 +00:00
Evan Cheng 8f2ed1bc5a Clean up. 
llvm-svn: 77221
 2009-07-27 18:25:24 +00:00
Evan Cheng 056c669e93 Get rid of some more getOpcode calls. 
This also fixes potential problems in ARMBaseInstrInfo routines not recognizing thumb1 instructions when 32-bit and 16-bit instructions mix.

llvm-svn: 77218
 2009-07-27 18:20:05 +00:00
Mike Stump 447a8f29ef Fix build. 
llvm-svn: 77217
 2009-07-27 18:18:30 +00:00
Sanjiv Gupta 96b3d4a2f9 Remove duplicate entries while printing decls for external symbols. 
Some libcall names are same, so they were getting printed twice.

llvm-svn: 77215
 2009-07-27 18:04:34 +00:00
Chris Lattner e48c85fa8b add an explanatory comment about why we drop these in readonly and 
not in mergable

llvm-svn: 77210
 2009-07-27 17:39:40 +00:00
Chris Lattner 1814e81e17 make COFF work like ELF and macho, by splitting out into its own 
header even though there is only one COFF target.

llvm-svn: 77204
 2009-07-27 16:45:59 +00:00
Chris Lattner ff1f401f9b don't create default text/data sections for all targets. 
llvm-svn: 77203
 2009-07-27 16:44:04 +00:00
Chris Lattner e25817a138 Apparently alpha doesn't use ElfTargetAsmInfo (?) 
llvm-svn: 77202
 2009-07-27 16:42:14 +00:00
David Goodwin 007031d1b4 Thumb-2 does not have RSC. 
llvm-svn: 77201
 2009-07-27 16:39:05 +00:00
David Goodwin 782f242fd7 Add ".w" suffix for wide thumb-2 instructions. 
llvm-svn: 77199
 2009-07-27 16:31:55 +00:00
Chris Lattner 543c83e8f2 inline a method. 
llvm-svn: 77198
 2009-07-27 16:27:32 +00:00
Chris Lattner 3679ad5a77 apparently we have "windows" and "coff", which are different(?) 
llvm-svn: 77197
 2009-07-27 16:22:39 +00:00
Chris Lattner c51f3394f3 sink text/data section creation down into the target-specific places that 
should know about them.  PECoff doesn't share these, and I want all sections
to be created by object-file-specific code.

llvm-svn: 77196
 2009-07-27 16:20:58 +00:00
Chris Lattner 469ae8ac54 32-bit darwin targets support .literal16 too. 
llvm-svn: 77191
 2009-07-27 15:44:04 +00:00
Chris Lattner 86b7255776 Eliminate getNamed/getUnnamedSection, adding a new and unified getOrCreateSection 
instead.

llvm-svn: 77186
 2009-07-27 06:17:14 +00:00
Chris Lattner 149465ea06 Eliminate SectionFlags, just embed a SectionKind into Section 
instead and drive things based off of that.

llvm-svn: 77184
 2009-07-27 05:32:16 +00:00
Evan Cheng 371ec9e810 If CPSR is modified but the def is dead, then it's ok to fold the load / store. 
llvm-svn: 77182
 2009-07-27 04:18:04 +00:00
Evan Cheng c47e109335 Use t2LDRi12 and t2STRi12 to load / store to / from stack frames. Eliminate more getOpcode calls. 
llvm-svn: 77181
 2009-07-27 03:14:20 +00:00
Sanjiv Gupta c8885129d8 Generate a libcall for i8 multiply. 
llvm-svn: 77179
 2009-07-27 02:44:46 +00:00
Sanjiv Gupta e334b34bfd fixed incorrect lowering of ISD::SUB node. SUB has only one result value. 
It wasn't caught during tests because we never got a sub generated, (i8 was always getting promoted to int, which in turn was broken into subc/sube). Though the optimizer leaves an i8 sub now. 

llvm-svn: 77178
 2009-07-27 02:26:06 +00:00
Evan Cheng 186332f898 Use the right instructions to copy between GPR and the more strictive tGPR classes. t2MOV does not match the RC requirements. 
llvm-svn: 77175
 2009-07-27 00:33:08 +00:00
Evan Cheng 0e5b149930 Merge isLoadFromStackSlot into one since it behaves the same regardless of sub-target. 
llvm-svn: 77174
 2009-07-27 00:24:36 +00:00
Evan Cheng 26b51b15ed Just use a single isMoveInstr to catch all the cases. 
llvm-svn: 77173
 2009-07-27 00:05:15 +00:00
Evan Cheng faede73a32 Rename tMOVhi2lor to tMOVgpr2tgpr. It's not moving from a high register to a low register. It's moving from a GPR register class to a more restrictive tGPR class. Also change tMOVlor2hir, and tMOVhir2hir. 
llvm-svn: 77172
 2009-07-26 23:59:01 +00:00
Chris Lattner 602d44fa70 untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create a 
'unnamed' bss section, but some impls would want a named one.  Since
they don't have consistent behavior, just make each target do their
own thing, instead of doing something "sortof common" then having
targets change immutable objects later.

llvm-svn: 77165
 2009-07-26 19:23:28 +00:00
Evan Cheng 8953720f23 Refactor. Get rid of a few more getOpcode() calls. 
llvm-svn: 77164
 2009-07-26 18:55:14 +00:00
Chris Lattner 06ad4948f5 reduce indentation 
llvm-svn: 77161
 2009-07-26 18:08:15 +00:00
Sanjiv Gupta fc4d4994ee Fix the breakage caused by 76950. 
PIC16 has special naming conventions for variables having section names specified via section attribute.

llvm-svn: 77153
 2009-07-26 10:25:01 +00:00
Nick Lewycky ec7ec7c1ac Move MSILModule and MSILWriter into the 'llvm' namespace, instead of the 'MSIL' 
namespace which could very well conflict with non-LLVM code.

Also clean up some spacing, remove an extra header.

llvm-svn: 77146
 2009-07-26 08:16:51 +00:00
Daniel Dunbar 9813b0b025 Eliminate some uses of DOUT, cerr, and getNameStart(). 
llvm-svn: 77145
 2009-07-26 07:49:05 +00:00
Chris Lattner 1db210322a remove a densemap from TargetAsmInfo that was uniquing the targetflags strings, 
just use a smallstring instead.

llvm-svn: 77144
 2009-07-26 07:33:58 +00:00
Chris Lattner d2e0220cb4 simplify SectionFlagsForGlobal, even though I want to kill it. 
llvm-svn: 77143
 2009-07-26 07:17:39 +00:00
Chris Lattner 9db3a9286d make SectionKind keep track of whether a global had an explicit 
section specified for it or not.

llvm-svn: 77142
 2009-07-26 07:14:28 +00:00
Chris Lattner d9951203f0 simplify this code now that SectionKind knows if a global is weak or not. 
llvm-svn: 77141
 2009-07-26 07:07:01 +00:00
Chris Lattner e45ff5cc2b make SectionKind know whether a symbol is weak or not in addition 
to its classification.

llvm-svn: 77140
 2009-07-26 07:00:12 +00:00
Chris Lattner 29151b0218 rename Mergable -> Mergeable and Writable -> Writeable 
llvm-svn: 77138
 2009-07-26 06:48:26 +00:00
Chris Lattner 2d7270d577 remove a bunch of helper functions, just use SectionKind::get instead. 
llvm-svn: 77135
 2009-07-26 06:34:33 +00:00
Chris Lattner fb6867c7db simplify getSectionForMergableConstant to take a SectionKind. 
llvm-svn: 77134
