Benjamin Kramer c758311025 Push twines deeper into SourceMgr's error handling methods. 
llvm-svn: 114847
 2010-09-27 17:42:11 +00:00
Chris Lattner 13ee795c42 remove unions from LLVM IR. They are severely buggy and not 
being actively maintained, improved, or extended.

Dan Gohman 7c7f13a5e6 Add a comment explaining why this code is more complex than it 
initially seems it should require.

llvm-svn: 111913
 2010-08-24 14:31:06 +00:00
Dan Gohman c828c5465d Extend function-local metadata to be usable as attachments. 
llvm-svn: 111895
 2010-08-24 02:24:03 +00:00
Dan Gohman 338d9a4935 Give ParseInstructionMetadata access to the PerFunctionState object. 
This is in preparation for generalizing its parsing of function-local
values.

llvm-svn: 111893
 2010-08-24 02:05:17 +00:00
Dan Gohman 8939ba337d Factor out metadata parsing into a separate function. 
llvm-svn: 108343
 2010-07-14 18:26:50 +00:00
Chris Lattner 2e664bd915 fix a crash on invalid metadata, e.g.: call i32 @foo(), XXXX 
We would return the error without inserting the new instruction
into the program, so it wouldn't get deallocated, and an abort
would trigger when the module was deleted.

Chris Lattner e04505e717 include header. 
llvm-svn: 100087
 2010-04-01 05:20:21 +00:00
Chris Lattner 8eff0157b2 rewrite handling of forward ref'd instruction metadata 
to used deferred resolution instead of creating a temporary
node + rauw.  There is no reason to create the temporary
mdnode, then do rauw, then destroy it.

llvm-svn: 96011
 2010-02-12 20:49:41 +00:00
Charles Davis be5557e86b Add a new function attribute, 'alignstack'. It will indicate (when the backends 
implement support for it) that the stack should be forcibly realigned in the
prologue (and the process reversed in the epilogue).

Devang Patel ac277eb930 Remove MetadataBase class because it is not adding significant value.

Victor Hernandez dc6e65a6a8 Re-add parsing of function-local metadata; this time with testcase. 
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. 
llvm-svn: 92288
 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.

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 f8d22fc77d Metadata.h doesn't need to include ValueHandle.h anymore.

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 
llvm-svn: 90497
 2009-12-03 23:40:58 +00:00
Devang Patel ba52f03052 Use WeakVH while storing metadata in containers. 
This fixes PR5393.

llvm-svn: 86091
 2009-11-05 01:13:02 +00:00
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.

llvm-svn: 85368

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 e297149e26 Auto-upgrade free instructions to calls to the builtin free function. 
Update all analysis passes and transforms to treat free calls just like FreeInst.
Remove RaiseAllocations and all its tests since FreeInst no longer needs to be raised.

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.
