not stop it by using RAII. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99832 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Refactor code to push DILocation prcessing into DwarfDebug.cpp from ↵Devang Patel
AsmPrinter.cpp. This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99816 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-22Emit DW_AT_low_pc and DW_AT_high_pc attributes for TAG_compile_unit.Devang Patel

2010-03-22DW_AT_stmt_list attribute attached with a compile unit encodes offset of ↵Devang Patel
line number information for this compile unit in debug_line section. This offset is always zero when only one compile unit is emitted in a object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99223 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-22Fix a memory leak from DIE::addSiblingOffset() by adding the DIEValueJeffrey Yasskin
it allocates to DwarfDebug::DIEValues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99196 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-17Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info ↵Devang Patel
so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98743 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16improve support for uniontype and ConstantUnion, patch by Tim Northover!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98656 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-16Fix the third (and last known) case of code update problems due Chris Lattner
to LLVM IR changes with addr label weirdness. In the testcase, we generate references to the two bb's when codegen'ing the first function: _test1: ## @test1 leaq Ltmp0(%rip), %rax .. leaq Ltmp1(%rip), %rax Then continue to codegen the second function where the blocks get merged. We're now smart enough to emit both labels, producing this code: _test_fun: ## @test_fun ## BB#0: ## %entry Ltmp1: ## Block address taken Ltmp0: ## BB#1: ## %ret movl $-1, %eax ret Rejoice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98595 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15Implement support for the case when a reference to a addr-of-bb Chris Lattner
label is generated, but then the block is deleted. Since the value is undefined, we just emit the label right after the entry label of the function. It might matter that the label is in the same section as the function was afterall. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98579 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15Emit dwarf variable info communicated by code generator through DBG_VALUE ↵Devang Patel
machine instructions. This is a work in progress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98556 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-14fix AsmPrinter::GetBlockAddressSymbol to always return a uniqueChris Lattner
label instead of trying to form one based on the BB name (which causes collisions if the name is empty). This fixes PR6608 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98495 91177308-0d34-0410-b5e6-96231b3b80d8

to get unique assembler temporary labels. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98489 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-14remove now-dead code, all labels use MCSymbols.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98484 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-14Now that DBG_LABEL is updated, we can finally make MachineMove Chris Lattner
contain an MCSymbol instead of a label index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98482 91177308-0d34-0410-b5e6-96231b3b80d8

with an MCSymbol instead of an immediate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98481 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-14change the LabelSDNode to be EHLabelSDNode and make it holdChris Lattner
an MCSymbol. Make the EH_LABEL MachineInstr hold its label with an MCSymbol instead of ID. Fix a bug in MMI.cpp which would return labels named "Label4" instead of "label4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98463 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-14use Label->isDefined() instead of isLabelDeleted() now that weChris Lattner
consistently use MCSymbol and only call this predicate after they should have been emitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98461 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-14change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner
instead of label ID's. This cleans up and regularizes a bunch of code and makes way for future progress. Unfortunately, this pointed out to me that JITDwarfEmitter.cpp is largely copy and paste from DwarfException/MachineModuleInfo and other places. This is very sad and disturbing. :( One major change here is that TidyLandingPads moved from being called in DwarfException::BeginFunction to being called in DwarfException::EndFunction. There should not be any functionality change from doing this, but I'm not an EH expert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98459 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13eliminate the now-unneeded context argument of MBB::getSymbol()Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98451 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13rearrange MCContext ownership. Before LLVMTargetMachine created it Chris Lattner
and passing off ownership to AsmPrinter. Now MachineModuleInfo creates it and owns it by value. This allows us to use MCSymbols more consistently throughout the rest of the code generator, and simplifies a bit of code. This also allows MachineFunction to keep an MCContext reference handy, and cleans up the TargetRegistry interfaces for AsmPrinters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98450 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13simplify EmitFrameMoves to take BaseLabel in as a symbolChris Lattner
instead of as a stem+idx pair, simplify the "is a new location" check to use symbol comparison. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98432 91177308-0d34-0410-b5e6-96231b3b80d8
