[lldb] [PECOFF] Only use PECallFrameInfo on the one supported architecture

2020-05-19T01:24:44+00:00

The RuntimeFunction struct, which PECallFrameInfo interprets, has a different layout and differnet semantics on all architectures. Differential Revision: https://reviews.llvm.org/D77000 (cherry picked from commit aa786b881fc89a2a9883bff77912f2053126f95b)

[lldb/DWARF] Move location list sections into DWARFContext

2020-01-14T14:19:29+00:00

These are the last sections not managed by the DWARFContext object. I also introduce separate SectionType enums for dwo section variants, as this is necessary for proper handling of single-file split dwarf.

[lldb] Fix lookup of symbols with the same address range but different binding

make err msg in MachSymtabSectionInfo::GetSection clear about the file

2019-12-19T00:13:17+00:00

This error message didn't specify which file was malformed, so there's some hunting-around required if it comes up. We have the filename; include it in the error message.

[lldb/MachO] "Fix" intentional out-of-bounds error (NFC)

2019-12-18T20:54:04+00:00

Remove the hack that populates the cpsr register in the gpr struct by writing past the end of the array. This was tripping up ASan. Patch by: Reva Cuthbertson

[LLDB] [PECOFF] Make sure to set the address byte size in m_data after parsing headers

2019-12-10T11:55:38+00:00

If not set, the address byte size was implied to be the one of the host process. This allows reverting the functional change from 31087b2ae9154, since now PECOFF does the same as ELF and MachO wrt setting both byte order and address size on m_data within ParseHeader.

[lldb] Remove FileSpec(FileSpec*) constructor

2019-12-04T09:49:25+00:00

This constructor was the cause of some pretty weird behavior. Remove it, and update all code to properly dereference the argument instead.

[LLDB] [PECOFF] Look for the truncated ".eh_fram" section name

2019-11-28T09:27:00+00:00

COFF section names can either be stored truncated to 8 chars, in the section header, or as a longer section name, stored separately in the string table. libunwind locates the .eh_frame section by runtime introspection, which only works for section names stored in the section header (as the string table isn't mapped at runtime). To support this behaviour, lld always truncates the section names for sections that will be mapped, like .eh_frame. Differential Revision: https://reviews.llvm.org/D70745

[LLDB] [PECOFF] Factorize mapping section names to types using StringSwitch. NFCI.

2019-11-28T09:27:00+00:00

Keep the existing special cases based on combinations of section name, flags and sizes/offsets. Differential Revision: https://reviews.llvm.org/D70778

[lldb] Add boilerplate to recognize the .debug_rnglists.dwo section
