*	[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label.	Shiva Chen	2018-05-09	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	Followup on Proposal to move MIR physical register namespace to '$' sigil.	Puyan Lotfi	2018-01-31	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \|	Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
*	[CodeGen] Print register names in lowercase in both MIR and debug output	Francis Visoiu Mistrih	2017-11-28	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \|	As part of the unification of the debug format and the MIR format, always print registers as lowercase. * Only debug printing is affected. It now follows MIR. Differential Revision: https://reviews.llvm.org/D40417 llvm-svn: 319187
*	SelectionDAG: Emit correct debug info for multi-register function arguments.	Adrian Prantl	2017-08-30	1	-0/+77
	Previously we would just describe the first register and then call it quits. This patch emits fragment expressions for each register. <rdar://problem/34075307> llvm-svn: 312169
