* Refactor.Devang Patel2011-04-051-1/+4
| | | | llvm-svn: 128929
* Remove dead code.Devang Patel2011-03-311-5/+1

* Collect and coalesce DBG_VALUE instructions before emitting the function.Jakob Stoklund Olesen2011-03-261-18/+26
| | | | | | | | | | | Correctly terminate the range of register DBG_VALUEs when the register is clobbered or when the basic block ends. The code is now ready to deal with variables that are sometimes in a register and sometimes on the stack. We just need to teach emitDebugLoc to say 'stack slot'. llvm-svn: 128327
* Emit less labels for debug info and stop emitting .loc directives for ↵Jakob Stoklund Olesen2011-03-251-1/+1
| | | | | | | | | | | | DBG_VALUEs. The .dot directives don't need labels, that is a leftover from when we created line number info manually. Instructions following a DBG_VALUE can share its label since the DBG_VALUE doesn't produce any code. llvm-svn: 128284
* Keep track of directory namd and fIx regression caused by Rafael's patch ↵Devang Patel2011-03-241-1/+1
| | | | | | | | r119613. A better approach would be to move source id handling inside MC. llvm-svn: 128233
* Reapply r128045 and r128051 with fixes.Jakob Stoklund Olesen2011-03-221-2/+10
| | | | | | | | | | | | | | | | This will extend the ranges of debug info variables in registers until they are clobbered. Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on the stack with DBG_VALUE instructions referring to variables in the frame pointer. This fixes the gdb test-suite failure. Fix 2: Don't trace through copies to physical registers setting up call arguments. These registers are call clobbered, and the source register is more likely to be a callee-saved register that can be extended through the call instruction. llvm-svn: 128114
* Revert r128045 and r128051, debug info enhancements.Andrew Trick2011-03-221-10/+2
| | | | | | Temporarily reverting these to see if we can get llvm-objdump to link. Hopefully this is not the problem. llvm-svn: 128097
* Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges.Jakob Stoklund Olesen2011-03-221-2/+10
| | | | | | | | | | 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
* If argument numbering is encoded in metadata then emit arguments' debug info ↵Devang Patel2011-03-011-2/+10
| | | | | | in that order. llvm-svn: 126794
* Roll out r126425 and r126450 to see if it fixes the failures on the buildbots.Cameron Zwarich2011-02-251-6/+0

* Emit 128 bit constant.Devang Patel2011-01-061-0/+1
| | | | | | This fixes PR 8913 crash. llvm-svn: 122971
* Change CodeGen to use .loc directives. This produces a lot more readable outputRafael Espindola2010-11-181-65/+4
| | | | | | | | 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
