Devang Patel 76a06074eb Revert r87059 for now. It is failing clang tests. 
llvm-svn: 87070
 2009-11-13 02:27:33 +00:00
Victor Hernandez 41e7648e09 Remove unnecessary llvm.dbg.declare bitcast 
llvm-svn: 87059
 2009-11-13 01:44:55 +00:00
Devang Patel 2904aa9f6e "Attach debug info with llvm instructions" mode was enabled a month ago. Now make it permanent and remove old way of inserting intrinsics to encode debug info for line number and scopes. 
llvm-svn: 87014
 2009-11-12 19:02:56 +00:00
Devang Patel 862ef782de Do not use StringRef in DebugInfo interface. 
This allows StringRef to skip controversial if(str) check in constructor.
Buildbots, wait for corresponding clang and llvm-gcc FE check-ins!

Devang Patel 33e0c99d67 Tolerate invalid derived type. 
llvm-svn: 86269
 2009-11-06 18:24:05 +00:00
Devang Patel cc11371b77 Do not bother to emit debug info for nameless global variable. 
llvm-svn: 86259
 2009-11-06 17:58:12 +00:00
Devang Patel f05d57283e While calculating original type size for a derived type, handle type variants encoded as DIDerivedType appropriately. 
This improves bitfield support.

llvm-svn: 86073
 2009-11-04 23:48:00 +00:00
Devang Patel 072b31a0bf If string field is empty then return NULL. 
llvm-svn: 85630
 2009-10-30 22:52:47 +00:00
Devang Patel 13cb281013 If a type is derived from a derived type then calculate size appropriately. 
llvm-svn: 85619
 2009-10-30 22:09:30 +00:00
Devang Patel 78c327f171 First bitcase use may not lead to a dbg.declare intrinsic. Iterate uses until one find's dbg.declare intrinsic. 
Patch by Sunae Seo.

llvm-svn: 85518
 2009-10-29 18:20:34 +00:00
Devang Patel c80b5c8707 Add support to encode type info using llvm::Constant. 
Patch by Talin!

Devang Patel c5cc659cfa "there is not any instruction with attached debug info in this module" does not mean "there is no debug info in this module". :) 
llvm-svn: 83984
 2009-10-13 17:35:35 +00:00
Bill Wendling 3dc625cdce It's possible for a global variable to be optimized out of a metadata object. So 
we should allow a "null" with this dyn_cast.

llvm-svn: 83573
 2009-10-08 20:52:51 +00:00
Devang Patel 55571bd7bd Extract subprogram and compile unit information from the debug info attached to an instruction. 
llvm-svn: 83491
 2009-10-07 22:04:08 +00:00
Mike Stump 70cb67fcf4 Expand api out in the usual inserter way, though, I do have a 
question, can we get rid of the BasicBlock versions of all inserters
and use Head == 0 to indicate the old case when GetInsertBlock == 0?

llvm-svn: 83216
 2009-10-01 22:08:58 +00:00
Devang Patel 34986f12e6 Add another MDNode into DebugLocTuple. This will be used to keep track of inlined functions. 
llvm-svn: 83190
 2009-10-01 01:15:28 +00:00
Devang Patel a49be76f43 Add isFOO() helpers. Fix getDirectory() and getFilename() for DIScope. 
llvm-svn: 83180
 2009-09-30 22:34:41 +00:00
Mike Stump 14cf8ecf0b Add a way for a frontend to generate more complex dwarf location 
information.  This allows arbitrary code involving DW_OP_plus_uconst
and DW_OP_deref.  The scheme allows for easy extention to include,
any, or all of the DW_OP_ opcodes.  I thought about just exposing all
of them, but, wasn't sure if people wanted the dwarf opcodes exposed
in the api.  Is that a layering violation?

With this scheme, the entire existing block scheme used by llvm-gcc
can be switched over to the new scheme.  I think that would be
cleaner, as then the compiler specific bits are not present in llvm
proper.  Before the old code can be yanked however, similar code in
clang would have to be removed.

Next up, more testing.

 2009-09-29 18:40:58 +00:00
Daniel Dunbar 0356483539 Switch DIDescriptor to use a TrackingVH. - This makes it much safer to work with debug info, since it was extraordinarily easy to have dangling pointers thanks to MDNode uniquing.

Devang Patel 80ae34974b Reapply 79977. 
Use MDNodes to encode debug info in llvm IR.

llvm-svn: 80406
 2009-08-28 23:24:31 +00:00
Devang Patel f08e35d9dc Revert 79977. It causes llvm-gcc bootstrap failures on some platforms. 
llvm-svn: 80073
 2009-08-26 05:01:18 +00:00
Devang Patel 02aac922b4 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. 
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

llvm-svn: 78335
 2009-08-06 20:57:44 +00:00
Owen Anderson 03cb69fbd1 Privatize the StructType table, which unfortunately involves routing contexts through a number of APIs. 
llvm-svn: 78258
 2009-08-05 23:16:16 +00:00
Owen Anderson 5a1acd9912 Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are 
metadata related, which I'm waiting on to avoid conflicting with Devang.
