Adrian Prantl bce66c31aa Debug info: Infrastructure to support debug locations for fragmented ... variables (for example, by-value struct arguments passed in registers, or large integer values split across several smaller registers). On the IR level, this adds a new type of complex address operation OpPiece to DIVariable that describes size and offset of a variable fragment. On the DWARF emitter level, all pieces describing the same variable are collected, sorted and emitted as DWARF expressions using the DW_OP_piece and DW_OP_bit_piece operators. http://reviews.llvm.org/D3373 rdar://problem/15928306 What this patch doesn't do / Future work: - This patch only adds the backend machinery to make this work, patches that change SROA and SelectionDAG's type legalizer to actually create such debug info will follow. (http://reviews.llvm.org/D2680) - Making the DIVariable complex expressions into an argument of dbg.value will reduce the memory footprint of the debug metadata. - The sorting/uniquing of pieces should be moved into DebugLocEntry, to facilitate the merging of multi-piece entries. llvm-svn: 214576		2014-08-01 22:11:58 +00:00
