2009-10-05If subprogram die is not available then construct new one.Devang Patel
This can happen if debug info is processed lazily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83347 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-05Adjust context for the global variables that are not at file scope, e.g.Devang Patel
void foo() { static int bar = 42; } Here, foo's DIE is parent of bar's DIE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83344 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-01Add support to extract lexical scope information from DebugLoc attached with ↵Devang Patel
an machine instruction. This is not yet enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83210 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-30Use MDNode * directly as an RecordSourceLine() argument.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83182 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-30Add a way for a frontend to generate more complex dwarf locationMike Stump
information. This allows arbitrary code involving DW_OP_plus_uconst and DW_OP_deref. The scheme allows for easy extention to include, any, or all of the DW_OP_ opcodes. I thought about just exposing all of them, but, wasn't sure if people wanted the dwarf opcodes exposed in the api. Is that a layering violation? With this scheme, the entire existing block scheme used by llvm-gcc can be switched over to the new scheme. I think that would be cleaner, as then the compiler specific bits are not present in llvm proper. Before the old code can be yanked however, similar code in clang would have to be removed. Next up, more testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83120 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-16eliminate the horrid AsmPrinter::getGlobalLinkName method, inliningChris Lattner
it into all of its call sites and simplifying them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81962 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11Don't generate Dwarf line table entries for source line 0.Caroline Tice
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81542 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-09remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner
the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80307 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26Add isClosure() predicate. This is used to add DW_AT_APPLE_block attribute.Devang Patel
Patch by Caroline Tice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80061 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-25Update DebugInfo interface to use metadata, instead of special named ↵Devang Patel
llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79977 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24prune the #includes in raw_ostream.h by moving a Chris Lattner
member out of line. ftostr is not particularly speedy, so that method is presumably not perf sensitive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79885 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Prune #includes from llvm/Linker.h and llvm/System/Path.h,Chris Lattner
forcing them down into various .cpp files. This change also: 1. Renames TimeValue::toString() and Path::toString() to ::str() for similarity with the STL. 2. Removes all stream insertion support for sys::Path, forcing clients to call .str(). 3. Removes a use of Config/alloca.h from bugpoint, using smallvector instead. 4. Weans llvm-db off <iostream> sys::Path really needs to be gutted, but I don't have the desire to do it at this point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79869 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-08sink the 'name' and 'isdirective' state out of MCSection into its derived ↵Chris Lattner
classes. This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78517 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-31switch off of 'Section' onto MCSection. We're not properly usingChris Lattner
MCSection subclasses yet, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77708 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77621 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner
it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77294 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77152 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Skip special LLVM prefix '1' while emitting linknage name.Devang Patel
This prefix is used by LLVM to inform the asm printer to not emit usual global symbol prefix before the symbol name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75875 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Change the internal interface to makeNameProper to take a bool thatChris Lattner
indicates whether the label is private or not, instead of taking prefix stuff. One effect of this is that symbols will be generated with *just* the private prefix, instead of both the private prefix *and* the user-label-prefix, but this doesn't matter as long as it is consistent. For example we'll now get "Lfoo" instead of "L_foo". These are just assembler temporary labels anyway, so they never even make it into the .o file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75607 91177308-0d34-0410-b5e6-96231b3b80d8
