Benjamin Kramer 6e046f4291 Use abs64 instead abs; some platforms don't have a 64-bit abs overload. Noticed by Yonggang Luo!

Nate Begeman a96114ed08 AltiVec-style vector initializer syntax, vec4 a = (vec4)(a, b, c, d); 
In addition to being defined by the AltiVec PIM, this is also the vector
initializer syntax used by OpenCL, so that vector literals are compatible
with macro arguments.

Daniel Dunbar d9631912cf llvm-mc/AsmParser: Fix thinko in ClassInfo::operator<. 
llvm-svn: 78533
 2009-08-09 08:23:23 +00:00
Daniel Dunbar e0891c2109 llvm-mc/AsmParser: Add hack to ignore Int_* and *_Int instructions for now, to 
make it easier to see interesting ambiguities.
 - Also, check that user doesn't try to redefine the super class. This is a wart
   in the current design, in that assembler match classes aren't explicitly
   declared somewhere (so there isn't a unique place to declare the super
   class). This should probably be fixed.

 2009-08-09 08:19:00 +00:00
Daniel Dunbar 5877782962 Disable this test for now, we don't check for super classes when matching yet. 
llvm-svn: 78531
 2009-08-09 07:35:56 +00:00
Daniel Dunbar 8e33cb2de1 llvm-mc/AsmParser: Implement user defined super classes. 
- We can now discriminate SUB32ri8 from SUB32ri, for example.

Bob Wilson f60c8807e8 Add a test for Neon VTRN instructions.

Daniel Dunbar f573b563e1 llvm-mc/AsmParser: Separate instruction ordering for ambiguity detection. 
- We want the ordering operation to be simple, since we run it on every
   match. The old ordering is also not a strict weak ordering when there are
   ambiguities, which makes MSVC unhappy.

 - While we are at it, detect all ambiguities instead of just the adjacent
   ones. There are actually 655, for X86.

Bob Wilson 45fa71a392 Change Neon table lookup (VTBL) and table extension (VTBX) intrinsics to 
take the table vectors as separate arguments, instead of the previous
approach where they were combined into one big vector.

Daniel Dunbar 447c4ab91d Extend comment on ParserMatchClass .td field, and add some missing 
classes for X86.

Daniel Dunbar d8c822f180 llvm-mc/AsmMatcher: Tweak string matcher (missed a newline). 
llvm-svn: 78518
 2009-08-08 23:43:16 +00:00
Chris Lattner 591105c540 sink the 'name' and 'isdirective' state out of MCSection into its derived classes. 
This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

Fariborz Jahanian 24f38969d5 ir-gen for initialization, in synthesize copy constructor, 
of base/field which have trivial copy constructor.

Anton Korobeynikov cfed3005e5 Use subclassing to print lane-like immediates (w/o hash) eliminating 
'no_hash' modifier. Hopefully this will make Daniel happy :)

Daniel Dunbar 5478125143 llvm-mc/AsmMatcher: Tweak string matcher. 
- Track whether we need to insert an explicit 'break'.

 - Invert conditional when matching a single prefix to reduce
   nesting/bracing/breaking.

 - wc -l of X86GenAsmMatcher.inc decreased by 10%. :)

Chris Lattner 3219d85f16 add a note about dead zero extends. 
llvm-svn: 78511
 2009-08-08 22:46:59 +00:00
Chris Lattner 1cb9396f4f 1. Make MCSection an abstract class. 
2. Move section switch printing to MCSection virtual method which takes a
   TAI.  This eliminates textual formatting stuff from TLOF.
3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and 
   TLOFELF::AtIsCommentChar.

llvm-svn: 78510
 2009-08-08 22:41:53 +00:00
Chris Lattner 089b7de20d switch this to create coff sections for now, it doesn't really matter for 
llvm-mc's purpose yet and we'll want to switch to creating semantic sections
at some point.

llvm-svn: 78509
 2009-08-08 22:38:48 +00:00
Eric Christopher 7dfa9f2e56 Add crc32 instruction and intrinsics. Add a new class of prefix 
bytes for F2 0F 38 and propagate. Add a FIXME for a set
of possibilities which correspond to intrinsics already used.

New test.

 2009-08-08 21:55:08 +00:00
Anders Carlsson f40886acca Refactor some code and implement support for global destructors for static variables. 
llvm-svn: 78507
 2009-08-08 21:45:14 +00:00
Jakob Stoklund Olesen e2dc8a46e9 Add support for READCYCLECOUNTER in Blackfin back-end. 
llvm-svn: 78506
 2009-08-08 21:42:22 +00:00
Chris Lattner 26cc5b78d0 add new PIC16Section class, this time hopefully not breaking the build :) 
llvm-svn: 78505
 2009-08-08 21:37:01 +00:00
Daniel Dunbar 66f4f54e8a llvm-mc/AsmMatcher: Switch token matching to use the new string matcher. 
Also, redefined MatchRegisterName to just return the register value or a
sentinel, to simplify the generated code.

 2009-08-08 21:22:41 +00:00
Daniel Dunbar 59410aaea6 Revert r78501, it doesn't build.

Chris Lattner 4a4e4487fc make PIC16 create its own custom MCSection. 
llvm-svn: 78501
 2009-08-08 20:55:25 +00:00
Chris Lattner 245fdfb9c3 make target-specific TLOF impls (except PIC16) create target-specific 
MCSection instances.

Chris Lattner 5a9bc50fa8 stub out PECOFF/MachO/ELF MCSection classes 
llvm-svn: 78499
 2009-08-08 20:50:49 +00:00
Chris Lattner c9ea8fddb2 eliminate TargetLoweringObjectFileSparc in favor of a TAI hook. 
A TAI hook is appropriate in this case because this is just an
asm syntax issue, not a semantic difference. TLOF should model
the semantics of the section.

 2009-08-08 20:43:12 +00:00
Jakob Stoklund Olesen dc6bccbaa6 Don't build illegal ops in DAGCombiner::SimplifyBinOpWithSameOpcodeHands(). 
Blackfin supports and/or/xor on i32 but not on i16. Teach
DAGCombiner::SimplifyBinOpWithSameOpcodeHands to not produce illegal nodes
after legalize ops.

llvm-svn: 78497
 2009-08-08 20:42:17 +00:00
Chris Lattner 36d04ec972 give pic16 a target-specific section creation name too 
llvm-svn: 78496
 2009-08-08 20:23:47 +00:00
Chris Lattner ce7d14032b now that getOrCreateSection is all object-file specific, 
give the impls an object-file-specific name.  In the future
they can take different arguments etc.

llvm-svn: 78495
 2009-08-08 20:22:20 +00:00
Chris Lattner 302041d5c9 sink getOrCreateSection down into all the object file implementations, 
now that they create *all* the sections.
