* Clear map after use.Jakob Stoklund Olesen2011-03-221-0/+1
| | | | | | This is likely to fix the segfault in llvm-gcc-x86_64-darwin10-cross-mingw32. llvm-svn: 128051
* Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges.Jakob Stoklund Olesen2011-03-221-30/+66
| | | | | | | | | | These ranges get completely jumbled by the post-ra scheduler, and it is not really reasonable to expect it to make sense of them. Instead, teach DwarfDebug to notice when user variables in registers are clobbered, and terminate the ranges there. llvm-svn: 128045
* Revert r127757, "Patch to a fix dwarf relocation problem on ARM. One-line fixDaniel Dunbar2011-03-161-5/+2
| | | | | | | plus the test where it used to break.", which broke Clang self-host of a Debug+Asserts compiler, on OS X. llvm-svn: 127763
* Patch to a fix dwarf relocation problem on ARM. One-line fix plus the test ↵Renato Golin2011-03-161-2/+5
| | | | | | where it used to break. llvm-svn: 127757
* Fix typo.Devang Patel2011-03-031-1/+1
| | | | llvm-svn: 126962
* Fix thinko in previous check-in.Devang Patel2011-03-031-1/+3
| | | | | | Add comment. llvm-svn: 126959
* llvm::Function argument count is not a good indicator of how many arugments ↵Devang Patel2011-03-031-1/+4
| | | | | | does the function have at source level. If we need more space, just resize vector conservatively. This vector is only used once per function. llvm-svn: 126957
* If argument numbering is encoded in metadata then emit arguments' debug info ↵Devang Patel2011-03-011-2/+32
| | | | | | in that order. llvm-svn: 126794
* Roll out r126425 and r126450 to see if it fixes the failures on the buildbots.Cameron Zwarich2011-02-251-11/+2
| | | | llvm-svn: 126488
* Enable DebugInfo support for COFF object files.Devang Patel2011-02-241-2/+11
| | | | | | Patch by Nathan Jeffords! llvm-svn: 126425
* Do not use DIFactory.Devang Patel2011-02-241-3/+4
| | | | llvm-svn: 126397
* Use DW_FORM_data2 for DW_AT_language and let users use ↵Devang Patel2011-02-231-1/+1
| | | | | | DW_LANG_lo_user=0x8000 to DW_LANG_hi_user=0xffff range. llvm-svn: 126339
* Do not emit empty DW_TAG_lexical_block DIEs. In one test case, size of ↵Devang Patel2011-02-191-17/+20
| | | | | | debug info reduced by almost 7%. llvm-svn: 126009
* Ignore DBG_VALUE machine instructions while constructing instruction ranges ↵Devang Patel2011-02-151-0/+4
| | | | | | | | based on location info. Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools. llvm-svn: 125577
* Merge .debug_loc entries whenever possible to reduce debug_loc size.Devang Patel2011-02-041-1/+10
| | | | llvm-svn: 124904
* Add support to describe template value parameter in debug info.Devang Patel2011-02-021-0/+20
| | | | llvm-svn: 124755
* Add support to describe template parameter type in debug info.Devang Patel2011-02-021-0/+27
| | | | llvm-svn: 124752
* Fix debug info for merged global.Devang Patel2011-01-201-0/+39
| | | | llvm-svn: 123862
* Fix register address expression. Patch by Ken Dyck.Devang Patel2011-01-191-4/+2
| | | | llvm-svn: 123856
* Appropriately truncate debug info range in dwarf output.Devang Patel2011-01-111-15/+5
| | | | | | This is not yet completely enabled. llvm-svn: 123274
* Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov2011-01-101-5/+5
| | | | | | and fixes here and there. llvm-svn: 123170
* Speculatively revert r123032.Devang Patel2011-01-071-5/+15
| | | | llvm-svn: 123039
* Appropriately truncate debug info range in dwarf output.Devang Patel2011-01-071-15/+5
| | | | | | Enable live debug variables pass. llvm-svn: 123032
* Emit 128 bit constant.Devang Patel2011-01-061-10/+37
| | | | | | This fixes PR 8913 crash. llvm-svn: 122971
* DW_FORM_data1 may not provide sufficient room for vtable index, use _udata ↵Devang Patel2010-12-091-1/+1
| | | | | | | | instead. This fixes radar 8730409. llvm-svn: 121323
* Undefined value in reg 0 may need a marker to identify end of source range.Devang Patel2010-12-061-4/+2
| | | | | | This will be used to truncate live range of DBG_VALUE instruction by register allocator and friends. llvm-svn: 121061
* Merge System into Support.Michael J. Spencer2010-11-291-1/+1
| | | | llvm-svn: 120298
* Move some more hooks to TargetFrameInfoAnton Korobeynikov2010-11-201-2/+2
| | | | llvm-svn: 119904
* Move getInitialFrameState() to TargetFrameInfoAnton Korobeynikov2010-11-181-1/+2
| | | | llvm-svn: 119754
* Change CodeGen to use .loc directives. This produces a lot more readable outputRafael Espindola2010-11-181-259/+19
| | | | | | | | and testing is easier. A good example is the unknown-location.ll test that now can just look for ".loc 1 0 0". We also don't use a DW_LNE_set_address for every address change anymore. llvm-svn: 119613
* Remove DW_AT_start_scope support. It is incomplete and superseeded by ↵Devang Patel2010-11-121-31/+6
| | | | | | location entries support. llvm-svn: 118940
* Take care of special characters while creating named MDNode name to hold ↵Devang Patel2010-11-101-10/+4
| | | | | | | | function specific local variable's info. This fixes radar 8653152. I am checking in testcase as a separate check-in. llvm-svn: 118726

| | | | llvm-svn: 117615
* Do not work too hard to find type's file info. There is a special field to ↵Devang Patel2010-10-281-2/+2
| | | | | | record file info. llvm-svn: 117588

* For statistics that are only used in functions declared in !NDEBUG, wrap theNick Lewycky2010-10-261-0/+2
| | | | | | | declarations in !NDEBUG to avoid -Wunused-variable warnings. Patch by Matt Beaumont-Gay! llvm-svn: 117345
* Add simple counter to count no. of basic blocks without any line number ↵Devang Patel2010-10-251-0/+28
| | | | | | information. At -O0, these basic block coule cause less than optimial debugging experience. llvm-svn: 117307
* Line number 0 indicates there is no source line/file name info available for ↵Devang Patel2010-10-081-1/+7
| | | | | | this construct. llvm-svn: 116061
* Provie a clearner interface so that FE can decide whether a function has ↵Devang Patel2010-10-071-6/+1
| | | | | | prototype or not. llvm-svn: 115988
* Add support for DW_TAG_unspecified_parameters.Devang Patel2010-10-061-6/+15
| | | | llvm-svn: 115833
* Add support to let FE mark explict methods as explict in debug info.Devang Patel2010-10-011-0/+2
| | | | llvm-svn: 115378
* Let FE mark a variable as artificial variable.Devang Patel2010-09-291-0/+2
| | | | llvm-svn: 115102
* Add support to let FE encode method access specifier.Devang Patel2010-09-291-1/+12
| | | | llvm-svn: 115089
* Assign DW_ACCESS_public accessibility attribute to members by default.Devang Patel2010-09-291-1/+10
| | | | llvm-svn: 115067
* Provide an interface to let FEs anchor debug info for types.Devang Patel2010-09-281-0/+4

* Remove dead argument.Devang Patel2010-09-271-4/+3

* Use DW_OP_fbreg when offset is based on frame register.Devang Patel2010-09-221-0/+10
| | | | llvm-svn: 114585
* If FE forgot to provide a file name (usually it uses "stdin" as name in such ↵Devang Patel2010-09-161-0/+4
| | | | | | situation) then make one up to ensure that debug info is not malformed. llvm-svn: 114119
