2016-08-12	Avoid accessing LLVM/DWARF register mappings if undefined	Dominic Chen	1	-0/+4
	Summary: If the backend does not define LLVM/DWARF register mappings, the associated variables are undefined since the map initializer is called by auto-generated TableGen routines. This patch initializes the pointers and sizes to nullptr and zero, respectively, and checks that they are valid before searching for a mapping.

2016-02-16	[codeview] Bail on a DBG_VALUE register operand with no register	Reid Kleckner	1	-1/+3
	This apparently comes up when the register allocator decides that a variable will become undef along a certain path. Also improve the error message we emit when we can't map from LLVM register number to CV register number. llvm-svn: 261016
2016-02-10	[codeview] Describe int local variables using .cv_def_range	Reid Kleckner	1	-0/+7
	Summary: Refactor common value, scope, and label tracking logic out of DwarfDebug into a common base class called DebugHandlerBase. Update an old LLVM IR test case to avoid an assertion in LexicalScopes. Reviewers: dblaikie, majnemer Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D16931 llvm-svn: 260432
2013-05-31	Make SubRegIndex size mandatory, following r183020.	Ahmed Bougacha	1	-9/+8
	This also makes TableGen able to compute sizes/offsets of synthesized indices representing tuples. llvm-svn: 183061
2013-05-31	Add a way to define the bit range covered by a SubRegIndex.	Ahmed Bougacha	1	-0/+13
	NOTE: If this broke your out-of-tree backend, in *RegisterInfo.td, change the instances of SubRegIndex that have a comps template arg to use the ComposedSubRegIndex class instead. In TableGen land, this adds Size and Offset attributes to SubRegIndex, and the ComposedSubRegIndex class, for which the Size and Offset are computed by TableGen. This also adds an accessor in MCRegisterInfo, and Size/Offsets for the X86 and ARM subreg indices. llvm-svn: 183020
2012-09-11	Add MCRI::getNumSubRegIndices() and start checking SubRegIndex ranges.	Jakob Stoklund Olesen	1	-0/+3
	Apparently, NumSubRegIndices was completely unused before. Adjust it by one to include the null subreg index, just like getNumRegs() includes the null register. llvm-svn: 163628
2012-07-27	Give MCRegisterInfo an implementation file.	Jakob Stoklund Olesen	1	-0/+71
	Move some functions from MCRegisterInfo.h that don't need to be inline. This shrinks llc by 8K. llvm-svn: 160865
