Consider regmasks when computing register-based DBG_VALUE live ranges Now register parameters that aren't saved to the stack or CSRs are considered dead after the first call.

Re-commit "DWARF location lists: Add section index dumping" This reapplies c0f6ad7d1f3ccb9d0b9ce9ef8dfa06409ccf1b3e with an additional fix in test/DebugInfo/X86/constant-loclist.ll, which had a slightly different output on windows targets. The test now accounts for this difference. The original commit message follows. Summary: As discussed in D70081, this adds the ability to dump section names/indices to the location list dumper. It does this by moving the range specific logic from DWARFDie.cpp:dumpRanges into the DWARFAddressRange class. The trickiest part of this patch is the backflip in the meanings of the two dump flags for the location list sections. The dumping of "raw" location list data is now controlled by "DisplayRawContents" flag. This frees up the "Verbose" flag to be used to control whether we print the section index. Additionally, the DisplayRawContents flag is set for section-based dumps whenever the --verbose option is passed, but this is not done for the "inline" dumps. Also note that the index dumping currently does not work for the DWARF v5 location lists, as the parser does not fill out the appropriate fields. This will be done in a separate patch.

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922

PR32288: More efficient encoding for DWARF expr subregister access. Citing http://bugs.llvm.org/show_bug.cgi?id=32288 The DWARF generated by LLVM includes this location: 0x55 0x93 0x04 DW_OP_reg5 DW_OP_piece(4) When GCC's DWARF is simply 0x55 (DW_OP_reg5) without the DW_OP_piece. I believe it's reasonable to assume the DWARF consumer knows which part of a register logically holds the value (low bytes, high bytes, how many bytes, etc) for a primitive value like an integer. This patch gets rid of the redundant DW_OP_piece when a subregister is at offset 0. It also adds previously missing subregister masking when a subregister is followed by another operation. (This reapplies r297960 with two additional testcase updates). rdar://problem/31069390 https://reviews.llvm.org/D31010 llvm-svn: 297965

[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label. In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.
