George Rimar	3832d7c25d	[LLD] - Do not crash when reporting errors when .debug_line_str (DWARF5) is used Imagine we have the following code: int foo(); int main() { return foo(); } It will crash if you try to compile it with `clang -O0 -gdwarf-5 test.cpp -o test -g -fuse-ld=lld` The crash happens inside the LLVM DWARF parser because LLD does not provide the .debug_line_str section. At the same time for correct parsing and reporting, we anyways need to provide this section from our side. The patch fixes the issue. llvm-svn: 343667	2018-10-03 08:59:46 +00:00

[LLD] - Do not crash when reporting errors when .debug_line_str (DWARF5) is used

Imagine we have the following code:

int foo();
int main() { return foo(); }

It will crash if you try to compile it with
`clang -O0 -gdwarf-5 test.cpp -o test -g -fuse-ld=lld`

The crash happens inside the LLVM DWARF parser because LLD does not provide
the .debug_line_str section. At the same time for correct parsing and reporting,
we anyways need to provide this section from our side.

The patch fixes the issue.

[ELF] - Do not fail on R_*_NONE relocations when parsing the debug info.

This is https://bugs.llvm.org//show_bug.cgi?id=38919.

Currently, LLD may report "unsupported relocation target while parsing debug info"
when parsing the debug information.

At the same time LLD does that for zeroed R_X86_64_NONE relocations,
which obviously has "invalid" targets.

The nature of R_*_NONE relocation assumes them should be ignored.
This patch teaches LLD to stop reporting the debug information parsing errors for them.

Rename GdbIndex.{cpp,h} -> DWARF.{cpp,h}.

These files used to contain classes and functions for .gdb_index,
but they are moved to SyntheticSections.{cpp,h}, so the name is now
irrelevant.
