2011-04-12This mechanical patch moves type handling into CompileUnit from DwarfDebug. ↵Devang Patel
In case of multiple compile unit in one object file, each compile unit is responsible for its own set of type entries anyway. This refactoring makes this obvious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129402 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-08Simplify array bound checks and clarify comments. One element array can ↵Devang Patel
have same non-zero number as lower bound as well as upper bound. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129170 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-08Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array.Devang Patel
If lower bound is more then upper bound then consider it is an unbounded array. An array is unbounded if non-zero lower bound is same as upper bound. If lower bound and upper bound are zero than array has one element. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129156 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-29Tidy up. 80 columns and trailing whitespace.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128504 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-26Collect and coalesce DBG_VALUE instructions before emitting the function.Jakob Stoklund Olesen
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'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128327 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-25Emit less labels for debug info and stop emitting .loc directives for ↵Jakob Stoklund Olesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128284 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24Keep track of directory namd and fIx regression caused by Rafael's patch ↵Devang Patel
r119613. A better approach would be to move source id handling inside MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128233 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-23Don't coalesce identical DBG_VALUE instructions prematurely.Jakob Stoklund Olesen
Each of these instructions may have a RegsClobberInsn entry that can't be ignored. Consecutive ranges are coalesced later when DwarfDebug::emitDebugLoc merges entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128155 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-22Reapply r128045 and r128051 with fixes.Jakob Stoklund Olesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128114 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-22Revert r128045 and r128051, debug info enhancements.Andrew Trick
Temporarily reverting these to see if we can get llvm-objdump to link. Hopefully this is not the problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128097 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-22Clear map after use.Jakob Stoklund Olesen
This is likely to fix the segfault in llvm-gcc-x86_64-darwin10-cross-mingw32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128051 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-22Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges.Jakob Stoklund Olesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128045 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-03llvm::Function argument count is not a good indicator of how many arugments ↵Devang Patel
