Directly point debug info to the stack slot of the arugment, instead of trying to keep track of vreg in which it the arugment is copied. The LiveDebugVariable can keep track of variable's ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139330 91177308-0d34-0410-b5e6-96231b3b80d8

Debug Info: Simplify Frame Index handling in DBG_VALUE Machine Instructions Rather than using the full power of target-specific addressing modes in DBG_VALUEs with Frame Indicies, simply use Frame Index + Offset. This reduces the complexity of debug info handling down to two representations of values (reg+offset and frame index+offset) rather than three or four. Ideally we could ensure that frame indicies had been eliminated by the time we reached an assembly or dwarf generation, but I haven't spent the time to figure out where the FIs are leaking through into that & whether there's a good place to convert them. Some FI+offset=>reg+offset conversion is done (see PrologEpilogInserter, for example) which is necessary for some SelectionDAG assumptions about registers, I believe, but it might be possible to make this a more thorough conversion & ensure there are no remaining FIs no matter how instruction selection is performed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184066 91177308-0d34-0410-b5e6-96231b3b80d8

Revert "Revert "PR14606: debug info imported_module support"" This reverts commit r179840 with a fix to test/DebugInfo/two-cus-from-same-file.ll I'm not sure why that test only failed on ARM & MIPS and not X86 Linux, even though the debug info was clearly invalid on all of them, but this ought to fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179996 91177308-0d34-0410-b5e6-96231b3b80d8

Upgrade tests to the latest debug info format. Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv, llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records (DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types, DISubprogram: local variables list) The tests to update were discovered by a change I'm working on to remove debug info version support - so any tests using old debug info versions I haven't updated probably are bad tests or just not actually designed to test debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176671 91177308-0d34-0410-b5e6-96231b3b80d8

Split out filename & directory from DIFile to start generalizing over DIScopes This is the first step to making all DIScopes have a common metadata prefix (so that things (using directives, for example) that can appear in any scope can be added to that common prefix). DIFile is itself a DIScope so the common prefix of all DIScopes cannot be a DIFile - instead it's the raw filename/directory name pair. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177239 91177308-0d34-0410-b5e6-96231b3b80d8
