Chris Lattner 60c2ca743d we don't need a smallptrset to detect duplicates, the values are 
sorted, so we can just do a linear scan.

 2009-12-31 03:02:42 +00:00
Chris Lattner 6a0ca6aa90 fix Analysis/DebugInfo.h to not include Metadata.h. Do this

llvm-svn: 92329
 2009-12-31 02:13:35 +00:00
Chris Lattner 1e6e36785e don't unittest mdnode printing, we have disassembler tests for this.

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.

 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.

Chris Lattner 8dace893fa tidy

 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: 92303
 2009-12-30 05:54:51 +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
and ignore a spurious comma after some instructions.

llvm-svn: 92300

Chris Lattner f4f0342b08 convert 4 more instructions over.

 2009-12-30 05:23:43 +00:00
Chris Lattner 28f1eebe3e reimplement insertvalue/extractvalue metadata handling to not blindly

llvm-svn: 92297
 2009-12-30 05:14:00 +00:00
Chris Lattner bafee45d2c remove two bogus calls that accepted metadata in the middle of insert/extract value 
*constant exprs*.

llvm-svn: 92296
 2009-12-30 05:04:46 +00:00
Chris Lattner eafe4de021 rename NamedOrCustomMD -> MetadataVar to follow conventions of all the rest of the code.
