From d6b2cdf9d4053ade22ad58379df7d12389ba3d1b Mon Sep 17 00:00:00 2001 From: Shiva Chen Date: Tue, 24 Jul 2018 02:22:55 +0000 Subject: [DebugInfo] Generate DWARF debug information for labels. There are two forms for label debug information in DWARF format. 1. Labels in a non-inlined function: DW_TAG_label DW_AT_name DW_AT_decl_file DW_AT_decl_line DW_AT_low_pc 2. Labels in an inlined function: DW_TAG_label DW_AT_abstract_origin DW_AT_low_pc We will collect label information from DBG_LABEL. Before every DBG_LABEL, we will generate a temporary symbol to denote the location of the label. The symbol could be used to get DW_AT_low_pc afterwards. So, we create a mapping between 'inlined label' and DBG_LABEL MachineInstr in DebugHandlerBase. The DBG_LABEL in the mapping is used to query the symbol before it. The AbstractLabels in DwarfCompileUnit is used to process labels in inlined functions. We also keep a mapping between scope and labels in DwarfFile to help to generate correct tree structure of DIEs.
