2011-05-10Rename DwarfRequiresRelocationForStmtList toRafael Espindola
DwarfRequiresRelocationForSectionOffset as this is not specific to StmtList. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131148 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130955 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-05If debug info for inlined function is missing then handle it gracefully.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130933 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-04Producing a DW_FORM_addr for DW_AT_stmt_list is probably correct, butRafael Espindola
it is both inefficient and unexpected by dwarfdump. Change to a DW_FORM_data4. While in here, change the predicate name to reflect that the position is not really absolute (it is an offset), just that the linker needs a relocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130846 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-04Tighten up check for empty (i.e. no meaningful debug info) module. This ↵Devang Patel
fixes dwarf-die2.c test case from gcc test suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130842 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-03Even if the subprogram is going to use AT_specification, emit ↵Devang Patel
DW_AT_MIPS_linkage_name. This helps gdb and fixes var-path-expr.exp regression reported by gdb testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130794 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-03If the front end has emitted llvm.dbg.cu and other debug info anchors (clang ↵Devang Patel
does it now) then use them directly. This saves one scan of entire module, to collect debug info, which in turns saves few machine cycles at compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130759 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-02Emit debug info for global variables first.Devang Patel
This works around a limitation in gdb which is reported by following inherit.exp test failures from gdb testsuite. gdb.cp/inherit.exp: print g_vB.vB::vb gdb.cp/inherit.exp: print g_vB.vB::vx gdb.cp/inherit.exp: print g_vC.vC::vc gdb.cp/inherit.exp: print g_vC.vC::vx gdb.cp/inherit.exp: print g_vD.vB::vb ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130702 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-28Teach dwarf writer to handle complex address expression for .debug_loc entries.Devang Patel
This fixes clang generated blocks' variables' debug info. Radar 9279956. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130373 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-27Simplify handling of variables with complex address (i.e. blocks variables)Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130339 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130171 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-25Do not drop a variable's complex address if it is not based on frame base.Devang Patel
Observed this while reading code, so I do not have a test case handy here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130167 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-22Let front-end tie subprogram declaration with subprogram definition directly.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130028 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-18Reduce clutter in asm output. Do not emit source location as comment for ↵Devang Patel
each instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129715 91177308-0d34-0410-b5e6-96231b3b80d8

Luis Felipe Strano Moraes! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129558 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-13Remove extra bytes that were added for gdb. We do not have good poiner to ↵Devang Patel
understand actual reason behind this fixme. Spot checking suggest that newer gdb does not need this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129461 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-12Simplify. There is no need to use static variable.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129406 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-04-12Refactor CompileUnit into a separate header.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129367 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
2011-04-05Add support to encode function's template parameters.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128947 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Do not emit empty name.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128914 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
