llvm-svn: 92330
 2009-12-31 02:15:45 +00:00
Chris Lattner bddea6a530 simplify mdnode printing logic. Now N->dump() only

Chris Lattner 2c48c64821 unify two copies of the NamedMDNode printing code.

 2009-12-31 01:54:05 +00:00
Chris Lattner b9196679f9 fix printing of function-local metadata to print all the operands of the 
mdnode, not just operand 0 over and over.

Chris Lattner cc8c8146d2 Remove #include of metadata.h from intrinsicinst.h. The only 
method that needs it (DbgValueInst::getValue) has been moved out
of line.

llvm-svn: 92323
 2009-12-31 01:32:41 +00:00
Chris Lattner 9b493028df rename "elements" of metadata to "operands". "Elements" are 
things that occur in types.  "operands" are things that occur
in values.

llvm-svn: 92322
 2009-12-31 01:22:29 +00:00
Chris Lattner 8cb6c3476d Optimize MDNode to coallocate the operand list immediately 
after the MDNode in memory.  This eliminates the operands
pointer and saves a new[] per node.

Note that the code in DIDerivedType::replaceAllUsesWith is wrong
and quite scary.  A MDNode should not be RAUW'd with something
else: this changes all uses of the mdnode, which may not be debug
info related!  Debug info should use something non-mdnode for
declarations.

 2009-12-31 00:51:46 +00:00
Chris Lattner 30ae06be14 do not bother reuniquing mdnodes whose operands drop to null. Doing 
so can be a huge performance issue when tearing down modules and mdnodes
are not guaranteed to be unique anyway.  This speeds up:
$ time ~/llvm/Release/bin/clang gcc.c -w -S -g

from 72 to 35s, where gcc.c is from:

llvm-svn: 92304
 2009-12-30 06:00:36 +00:00
Chris Lattner 94b9c5a73b now that instruction metadata is only parsed in one place, eliminate the 
parser-global MDsOnInst vector and make ParseInstructionMetadata return
its result by-ref through an argument like the entire rest of the parser.

llvm-svn: 92302
 2009-12-30 05:48:36 +00:00
Chris Lattner b2f3950da7 reimplement ParseOptionalInfo as ParseOptionalCommaAlign, correctly 
handle the comma case for metadata.

llvm-svn: 92301
 2009-12-30 05:44:30 +00:00
Chris Lattner 5c42763452 rename ParseOptionalCustomMetadata -> ParseInstructionMetadata, 
and make it non-optional.  This fixes the bug where we'd accept

 2009-12-30 05:02:06 +00:00
Chris Lattner 1eed2d65c0 rename lltok::Metadata -> lltok::exclaim. We name tokens 
after their syntactic form, not their semantic form.

llvm-svn: 92294
 2009-12-30 04:56:59 +00:00
Chris Lattner fc58af26d5 rename MetadataCache -> NumberedMetadata to follow the convention 
used by other things.  Convert it to a vector since it is a dense 
numbering.

llvm-svn: 92293
 2009-12-30 04:51:58 +00:00
Chris Lattner a01ddfc2a3 rewrite ParseMDNodeVector to follow the normal patter used in the .ll parser. 
llvm-svn: 92292
 2009-12-30 04:42:57 +00:00
Chris Lattner 6dac02a4f7 rename ParseMDNode -> ParseMDNodeID, since it parses !42, not !{... } as you'd expect. 
llvm-svn: 92291

 2009-12-29 22:01:50 +00:00
Chris Lattner 1797fc7009 change ParseMDString and ParseMDNode to take arguments of the right type. 
This exposed a raft of other problems, which I'll deal with in subsequent
patches.

llvm-svn: 92273
 2009-12-29 21:53:55 +00:00
Chris Lattner 218b22f33b switch to TrackingVH instead of WeakVH, since these can never 
be RAUW'd and go to null.  This also gets us some sorely lacking
type safety.

llvm-svn: 92272
 2009-12-29 21:43:58 +00:00
Chris Lattner 596760d9bb Each instruction is allowed to have *multiple* different 
metadata objects on them.  Though the entire compiler supports this,
the asmparser didn't.

Chris Lattner a0566979b7 Final step in the metadata API restructuring: move the 
getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

Sanjiv Gupta 015215ca86 Extern declaration for unordered.f32 libcall was not being emitted. Fixed that. 
llvm-svn: 92242
 2009-12-29 03:24:34 +00:00
Chris Lattner 241264ee32 When doing v1->RAUW(v2), don't do anything to metadata. We don't know 
why one was replaced with the other.  Even in the specific case of 
debug information, it doesn't make sense to transfer the location over,
this will just result in jumbled loc info.

llvm-svn: 92241
 2009-12-29 02:53:52 +00:00
Chris Lattner d8eb2cf571 sink the Instruction::HasMetadata bit into SubclassData. 
llvm-svn: 92240
 2009-12-29 02:46:09 +00:00
Chris Lattner b9c8651b8c add a layer of accessors around the Value::SubClassData member, and use 
a convention (shadowing the setter with private forwarding function) to
prevent subclasses from accidentally using it.

This exposed some bogosity in ConstantExprs, which was propaging the
opcode of the constant expr into the NUW/NSW/Exact field in the
getWithOperands/getWithOperandReplaced methods.

llvm-svn: 92239
 2009-12-29 02:14:09 +00:00
Chris Lattner 2f2aa2b067 This is a major cleanup of the instruction metadata interfaces that 
I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.

Chris Lattner 17079fc0fa split code that doesn't need to be templated out of IRBuilder into a new

llvm-svn: 92227
 2009-12-28 21:28:46 +00:00
Chris Lattner 7093946ab1 rename getMDKind -> getMDKindID, make it autoinsert if an MD Kind

llvm-svn: 92225
 2009-12-28 20:45:51 +00:00

Chris Lattner 588096e51d Rewrite the function-local validation logic for MDNodes (most of r91708). 
Among other benefits, this doesn't leak the SmallPtrSet, has the verifier
code in the verifier pass, actually does the verification at the end,
and is considerably simpler.

Chris Lattner 74a6ad6f29 move ElementVH out of the MDNode class into the MDNode.cpp file. Among 
other things, this avoids vtable and rtti data for it being splatted in 
every translation unit that uses it.
