* 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: 118027
* Ignore empty blocks.Devang Patel2010-10-281-1/+1
| | | | 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
* Technically DIFile scope should also be handled here.Devang Patel2010-10-281-0/+4

* 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
| | | | llvm-svn: 114969
* Remove dead argument.Devang Patel2010-09-271-4/+3
| | | | llvm-svn: 114920
* 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
* Fix .debug_range for linux. Patch by Krister Wombell.Devang Patel2010-09-021-4/+11
| | | | llvm-svn: 112830
* Use absolute label for DW_AT_stmt_list if a target does not prefer offset here.Devang Patel2010-08-311-1/+5
| | | | | | This patch was developed on top of original patch by Artur Pietrek. llvm-svn: 112678

| | | | llvm-svn: 112659
* Revert r112623. It is causing self host build failures.Devang Patel2010-08-311-10/+3
| | | | llvm-svn: 112631
* Remember byval argument's frame index during argument lowering and use this ↵Devang Patel2010-08-311-3/+10
| | | | | | | | info to emit debug info. Fixes Radar 8367011. llvm-svn: 112623
