Anders Carlsson 995891667f Use the canonical destructor, which fixes the self-host build. Thanks to Eli for noticing.

Daniel Dunbar 30b24e95fa Frontend: Don't free the CompilerInstance or FrontendActions when running under 
-disable-free. Among other things, this fixes freeing of the LLVM module on
exit.
 - Note that this means we are disable-free'ing of a lot more stuff than we used to -- this should flush out bugs in anything left that is trying to do real work in its destructor. I did a mini-audit but '::~' is not totally uncommon.

Daniel Dunbar cb9eaf59fb PPCallbacks: Add hook for reaching the end of the main file, and fix DependencyFile to not do work in its destructor.

Daniel Dunbar de04b3f62c MC: Switch to using MCInst fragments to do relaxation. 
Also, both MCMachOStreamer and MCAssembler are now target independent!

 2010-03-23 05:09:03 +00:00
Zhongxing Xu 3c0c81a4d4 Since we now may have basicblocks with the same block is in different function, 
change the block counter map from unsigned -> unsigned to 
<StackFrameContext*, unsigned> -> unsigned.

Anders Carlsson 917229cf75 Baby steps towards making thunks be emitted from the new vtable layout code. 
llvm-svn: 99254
 2010-03-23 04:59:02 +00:00
Anders Carlsson 7cea12ff9b Some renames. 
llvm-svn: 99253
 2010-03-23 04:44:10 +00:00
Anders Carlsson af82f63b47 Always emit associated thunks when emitting the function itself. Remove getVtableAddressPoint, it's not used.

 2010-03-23 04:31:31 +00:00
Anders Carlsson 8841024a7c Rename MaybeEmitVtable to EmitVTableRelatedData in preparation for making it emit thunks as well. 
llvm-svn: 99251

Anders Carlsson a864caff8c Rename CGVtableInfo to CodeGenVTables in preparation of adding another VTableInfo class.

Daniel Dunbar 86face8333 MC: Add TargetAsmBackend::MayNeedRelaxation, for checking whether a particular instruction + fixups might need relaxation. 
llvm-svn: 99249
 2010-03-23 03:13:05 +00:00
Daniel Dunbar a9ae3ae698 MC: Add TargetAsmBackend::WriteNopData and use to eliminate some target dependencies in MCMachOStreamer and MCAssembler. 
llvm-svn: 99248
 2010-03-23 02:36:58 +00:00
Daniel Dunbar e0c43577c1 MC: Add TargetAsmBackend::RelaxInstruction callback, and custom X86 implementation. 
llvm-svn: 99245
 2010-03-23 01:39:09 +00:00
Daniel Dunbar 16cbe95dd6 MC: Tweak MCInstFragment to include the encoded data and fixups, so that we don't need to recompute them during relaxation. I will revisit this once all the other pieces of fast relaxation are in place.

Ted Kremenek a3ab0d7666 For forward-declared static inline functions, delay CFG-based warnings until we 
encounter a definition.

Ted Kremenek bb6f5af4a4 Tweak null dereference diagnostics to give clearer diagnostics when 
a null dereference results from a field access.

Rafael Espindola 8d04f0604e A fixed version of r99174 which also includes a test that we emit vtables when 
we see an specialization definition ever if we then see a extern template declaration.

Devang Patel 53e91f0836 DW_AT_stmt_list attribute attached with a compile unit encodes offset of line number information for this compile unit in debug_line section. This offset is always zero when only one compile unit is emitted in a object file.
