Devang Patel 7a9dedf0ab Do not drop location info for inlined function args.
llvm-svn: 104884
2010-05-27 20:25:04 +00:00
Devang Patel 5e6b71ce34 inlined function's arguments need a label to mark the start point because they are not directly attached to current function.

2010-05-26 23:55:23 +00:00
Devang Patel acc32a5c19 There is no need to force an line number entry (using previous location) for a temp label at unknown location.

2010-05-26 21:23:46 +00:00
Devang Patel 002d54ddc9 Identify instructions, that needs a label to mark debug info entity, in advance. This simplifies beginScope().

2010-05-26 17:29:32 +00:00
Devang Patel 9fc11706e3 First cut at supporting .debug_loc section.
This is used to track variable information.

Eric Christopher f3925438e5 Move the verbose asm output up a bit so it can be used in the special cases
as well.

2010-05-25 21:49:43 +00:00
Eric Christopher 19a4b843cc Add support for initialized global data for darwin tls. Update comments
and testcases accordingly.

llvm-svn: 104635
2010-05-25 21:28:50 +00:00
Devang Patel 51b37e0bd8 Do not emit line number entries for unknown debug values.
This fixes recent regression in store.exp from gdb testsuite.

Nicolas Geoffray c5327226e4 Encode the Caml frametable by following what the comment says: the number of descriptors
is first emitted, and StackOffsets are emitted in 16 bits.

Devang Patel 490c8ab76d Refactor.
llvm-svn: 104265
2010-05-20 19:57:06 +00:00
Devang Patel e1c53f29d3 Split DbgVariable. Eventually, variable info will be communicated through frame index, or DBG_VALUE instruction, or collection of DBG_VALUE instructions. Plus each DbgVariable may not need a label.

Devang Patel 0fe341e2e2 There is no need to maintain InsnsBeginScopeSet separately.
llvm-svn: 104165
2010-05-19 21:26:53 +00:00
Devang Patel 36debf8046 Do not forget to mark prcessed arguments.
llvm-svn: 103822
2010-05-14 21:55:50 +00:00
Bill Wendling 95f6ebcb37 Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

llvm-svn: 103802
2010-05-14 21:14:32 +00:00
Devang Patel e0a94bfe9f Add support to preserve type info for the variables that are removed by the optimizer.

2010-05-14 21:01:35 +00:00
Daniel Dunbar 3439ed6324 Inline Asm: Ensure buffer is newline terminated to match how the text is printed.
- This is a hack, but I can't decide the best place to handle this. Chris?

2010-05-14 04:31:50 +00:00
Duncan Sands 2576db727b Remove unused variable. Tweak a comment while there.
llvm-svn: 103586
2010-05-12 07:11:33 +00:00
Nathan Jeffords 76a07580ad updated support for the COFF .linkonce
Now, the .linkonce directive is emitted as part of MCSectionCOFF::PrintSwitchToSection instead of AsmPrinter::EmitLinkage since it is an attribute of the section the symbol was placed into not the symbol itself.

llvm-svn: 103568
2010-05-12 04:26:09 +00:00
Devang Patel 1a0df9a80e Enable multiple Compile Units in one module.
This means now 'llvm-ld a.bc b.bc' will preserve debug info appropriately.

llvm-svn: 103439
2010-05-10 22:49:55 +00:00
Devang Patel 0625af2a88 Instead of just verifying compile unit, verify entire type, variable, namespace etc..
llvm-svn: 103327
2010-05-07 23:33:41 +00:00
Devang Patel cbe7a8508a Remove DIGlobal.
llvm-svn: 103325
2010-05-07 23:19:07 +00:00
Devang Patel 8d6a2b7428 Verify entire type descriptor not just tag.
llvm-svn: 103303
2010-05-07 21:45:47 +00:00
Devang Patel 32cc43c242 Wrap const MDNode * inside DIDescriptor.
llvm-svn: 103295
2010-05-07 20:54:48 +00:00
Devang Patel cfa8e9d45f Avoid DIDescriptor::getNode(). Use overloaded operators instead.
llvm-svn: 103272
2010-05-07 18:11:54 +00:00
Dan Gohman 7421ae48bf Disable the new unknown-location code for now. It causes a major
increase in the debug line info section, and it's causing
regressions in a gdb testsuite.

llvm-svn: 103226
2010-05-07 01:08:53 +00:00
Dan Gohman 47d04e3e41 Update LabelsBeforeInsn also, when creating unknown-position labels.
llvm-svn: 103145
2010-05-06 00:29:41 +00:00
Chris Lattner 35096e82c5 Fix PR7054 - Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed.
Users can write broken code that emits the same label twice with asm renaming,
detect this and emit a fatal backend error instead of aborting.

llvm-svn: 103140
2010-05-06 00:05:37 +00:00
Dan Gohman 50849c63e4 Emit debug info for MachineInstrs with unknown debug locations, instead
of just letting them inherit the debug locations of adjacent instructions.

Debug info should aim to be either accurate or absent.

llvm-svn: 103135
2010-05-05 23:41:32 +00:00
Devang Patel 075e9b5d66 Set DW_AT_APPLE_omit_frame_ptr in endFunction() where MachineFunction is available all the time.
llvm-svn: 103001
2010-05-04 06:15:30 +00:00
Dale Johannesen 1ebb395cee Don't count debug info as instructions. This was
preventing the emission of the NOP on Darwin for a
function with no actual code.  From timberwolfmc
with TEST=optllcdbg.

llvm-svn: 102843
2010-05-01 16:41:11 +00:00
Devang Patel b4e3b9025c Attach AT_APPLE_optimized attribute to optimized function's debug info.
llvm-svn: 102743
2010-04-30 19:38:23 +00:00
Devang Patel 080e4fb2f0 Print variable scope name in DEBUG_VALUE comment. Useful in some cases. e.g.
##DEBUG_VALUE: runOnMachineFunction:this <- RDI+0
	##DEBUG_VALUE: runOnMachineFunction:fn <- RSI+0
	##DEBUG_VALUE: DeadDefs <- undef ## SimpleRegisterCoalescing.cpp:2706
	##DEBUG_VALUE: getRegInfo:this <- [%rsp+$56]+$0
	##DEBUG_VALUE: getTarget:this <- [%rsp+$56]+$0

Chris Lattner 08e9e72fa9 Rework global alignment computation again. Now we do round up
alignment of globals to the preferred alignment, but only when
there is no section specified on the global (by far the common
case).

llvm-svn: 102515
2010-04-28 19:58:07 +00:00
Devang Patel 50c9431203 Emit debug info for byval parameters.
