Victor Hernandez 9d75c966e0 Consolidate ConvertGlobalValIDToValue, ConvertGlobalOrMetadataValIDToValue, and ConvertValIDToValue into a more powerful ConvertValIDToValue() that does all three's work

llvm-svn: 92793
 2010-01-05 22:22:14 +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
 2009-12-30 05:31:19 +00:00
Chris Lattner f4f0342b08 convert 4 more instructions over. 
llvm-svn: 92299
 2009-12-30 05:27:33 +00:00
Chris Lattner 77b89dc58b add facilities to start factoring instruction metadata parsing 
out of each opcode's handler.  Change ret over so far.

llvm-svn: 92298
 2009-12-30 05:23:43 +00:00
Chris Lattner 28f1eebe3e reimplement insertvalue/extractvalue metadata handling to not blindly 
accept invalid input.  Actually add a testcase.

llvm-svn: 92297
 2009-12-30 05:14:00 +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
 2009-12-30 04:15:23 +00:00
Chris Lattner 95471e49c5 remove the code added in r90497. It has several major issues and no tests.

 2009-12-30 02:20:07 +00:00
Chris Lattner 5b4a962bdd split t_Metadata into t_MDNode and t_MDString, eliminating some unsafe casting. 
llvm-svn: 92287
 2009-12-30 02:11:14 +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.

 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.

Victor Hernandez fa23223d4a Add ParseInlineMetadata() which can parses metadata that refers to an instruction. Extend ParseParameterList() to use this new function so that calls to llvm.dbg.declare can pass inline metadata

Chris Lattner 3432c62d93 full asmparser support for blockaddress. We can now do: 
$ llvm-as foo.ll -d -disable-output

which reads and prints the .ll file.  BC encoding is the
next project.  Testcase will go in once that works.

Chris Lattner d04cb6d0fa rename indbr -> indirectbr to appease the residents of #llvm. 
llvm-svn: 85351
 2009-10-28 00:19:10 +00:00
Chris Lattner 3ed871fe62 add enough support for indirect branch for the feature test to pass 
(assembler,asmprinter, bc reader+writer) and document it.  Codegen
currently aborts on it.

Victor Hernandez c7d6a8327c Autoupgrade malloc insts to malloc calls. 
Update testcases that rely on malloc insts being present.

Also prematurely remove MallocInst handling from IndMemRemoval and RaiseAllocations to help pass tests in this incremental step.

Nick Lewycky 49f891958f Add support for embedded metadata to LLVM. This introduces two new types of 
Constant, MDString and MDNode which can only be used by globals with a name
that starts with "llvm." or as arguments to a function with the same naming
restriction.

Chris Lattner f880ca2a31 Fix two classes of bugs. First: 
validate an invariant so that the asmparser rejects a bad construct
instead of the verifier.  Before:

llvm-as: assembly parsed, but does not verify as correct!
Invalid struct return type!
i64 (%struct.Type*, %struct.Type*)* @foo

after:

llvm-as: t.ll:5:8: functions with 'sret' argument must return void
define i64 @foo(%struct.Type* noalias nocapture sret %agg.result, %struct.Type* nocapture byval %t) nounwind {
       ^


Second, check that void is only used where allowed (in function return types) not in
arbitrary places, fixing PR3747 - Crash in llvm-as with void field in struct.  We
now reject that example with:

$ llvm-as t.ll
llvm-as: t.ll:1:12: struct element can not have void type
%x = type {void}
           ^
