Pavel Labath	c573032ded	Add "REQUIRES: x86" to DWARF assembly tests ... These tests don't require an x86 host, but they do require that we build the x86 llvm target. llvm-svn: 362948	2019-06-10 15:08:00 +00:00
Pavel Labath	1a8630ac28	DWARFContext: Return empty data extractors instead of null pointers ... Summary: There are several reasons for doing this: - generally, there's no reason to differentiate between a section being absent and it being present, but empty - it matches more closely what llvm DWARF parser is doing (which also doesn't differentiate the two cases) - SymbolFileDWARF also doesn't differentiate the two cases, which makes porting the rest of sections easier - it fixes a bug in how the return-null-if-empty logic was implemented (it returned nullptr only the second time we tried to get the debug_aranges section), which meant that we hit an assert when trying to parse an empty-but-present section Reviewers: JDevlieghere, clayborg, aprantl Subscribers: zturner, lldb-commits Differential Revision: https://reviews.llvm.org/D61942 llvm-svn: 360874	2019-05-16 11:19:02 +00:00
