The same adjustment is already done for the entry point in
Writer.cpp and for relocations that point to executable code
in Chunks.cpp.

Also add the test cases for the addition and subtraction both for

We were not looking at Repl and so thinking there was no output
section associated with the merged symbol. Because of that it was
produced as absolute.
This was found by an internal round of testing.

SHF_GROUP flag should have been removed when the control reaches here
because InputSectionBase turns the flag off. So this code should be
redundant.

Summary:
If the linker is invoked with `--chroot /foo` and `/bar/baz.o`, it
tries to read the file from `/foo/bar/baz.o`. This feature is useful
when you are dealing with files created by the --reproduce option.

Also extend the tests for IMAGE_REL_ARM64_PAGEOFFSET_12L to test
all 8/16/32/64 bit GPR and 8/16/32/64/128 SIMD/FP bit ldr/str variants,
and a ldr with an existing offset.

Fix issues found in existing code, while reviewing other changes.
Change the data type of a variable to uint32_t, to avoid potential issues
with signedness in shifts.

This fixes cases on ARM64 when importing from more than one DLL,
in case the imports from the first DLL ended up unaligned.
When fixing up a IMAGE_REL_ARM64_PAGEOFFSET_12L, which shifts the
offset by the load/store size, check that the shift doesn't discard
any bits. (This would also detect if the import address chunks were
unaligned.)

With that in place we can use lld's own infrastructure for the low
level detail of dwarf parsing.
With this we don't decompress sections twice, we don't scan all
realocations and even with this simplistic implementation linking
clang with gdb index goes from 34.09 seconds to 20.80 seconds.

In addition this includes a change to prefer symbols with a default
version @@ over unversioned symbols.
Original commit message:
[ELF] - Handle symbols with default version early.
This fixes last testcase provided in PR28414.
In short issue is next: when we had X@@Version symbol in object A,
we did not resolve it to X early. Then when in another object B
we had reference to undefined X, symbol X from archive was fetched.
Since both archive and object A contains another symbol Z, duplicate
symbol definition was triggered as a result.
Correct behavior is to use X@@Version from object A instead and do not fetch
any symbols from archive.

This test is folded into implib-name. Don't bother with the racy test.
The use of %T results in left-overs from previous tests which write out
the same import library as this test.

Improve the link conformance for the import name embedded into the
import library. This requires the associated change to the LLVM portion
for the DEF file parser. The import file generation embeds a different
name based on whether the driver is invoked as "link" or "lib".
Furthermore, the LIBRARY keyword in the DEF file influences the import
name. The behaviour can be summarised according to the following table:
| LIBRARY w/ ext | LIBRARY w/o ext | no LIBRARY
-----+----------------+---------------------+------------------
LINK | {value} | {value}.{.dll/.exe} | {output name}
LIB | {value} | {value}.dll | {output name}.dll

Noticed while testing for an out of tree target. There are probably more tests that should be so marked.
I'm not sure who owns these tests so I've added a few names I recognise from the recent history.
With advice from probinson, ruiu, rafael and dramatically improved by davidb. Thank you all!

DWARF debug sections can also contain relocations against symbols in
discared segments. LLD should accept such relocations.

Assume that the LF_TYPESERVER2 record contains Windows-style paths. In
any case, 'sys::path::filename(Path, Style::windows)' will work on
Unix-style paths.
llvm-svn: 308241
Summary:
Object files compiled with /Zi emit type information into a type server
PDB. The .debug$S section will contain a single TypeServer2Record with
the absolute path and GUID of the type server. LLD needs to load the
type server PDB and merge all types and items it finds in it into the
destination PDB.
Depends on D35495
