Summary:
With D43396, no clients use the Path parameter anymore.
This is the lld side fix with D43400.
Depends on D43396 and D43400.

This header used to be needed here for the `OutRelocation` struct
but that no longer exists.

Instead include InputFuction and InputSegment directly
in the subclasses that use them (DefinedFunction and
DefinedGlobal).

This patch removes `OutRelocations` vector from the InputChunk and
directly consume `Relocations` vector instead. This should make the linker
faster because we don't create a temporary data structure, and it matches
the lld's design principle that we don't create temporary data structures
for object files but instead directly consume mmap'ed data whenever possible.

Summary:
Before the name of the function sounded like it was just a getter for the
private class member Addend. However, it actually calculates the final
value for the r_addend field in Elf_Rela that is used when writing the
.rela.dyn section. I also added a comment to the UseSymVA member to
explain how it interacts with computeAddend().

We already have isa<> for this, and these methods were simply
duplicating those redundantly.

Currently, archive file name is missing in this message. In general,
we should avoid constructing strings in an ad-hoc manner and instead
use toString() to get consistent output strings.

We are running lld tests with "--full-shutdown" option because we don't
want to call _exit() in lld if it is running tests. Regular shutdown
is needed for leak sanitizer.
This patch changes the way how we tell lld that it is running tests.
Now "--full-shutdown" is removed, and LLD_IN_TEST environment variable
is used instead.
This patch enables full shutdown on all ports, e.g. ELF, COFF and wasm.
Previously, we enabled it only for ELF.

Invoking lld as ld.lld, ld.ld64, lld-link or wasm-ld is preferred
than invoking lld as lld and pass an -flavor option. We have "lld"
file mostly for historical reasons.

This is required after r325399:
- EF_AMDGPU_ARCH_GCN got removed
- In the test, EF_AMDGPU_ARCH_GCN is replaced with EF_AMDGPU_MACH_AMDGCN_GFX803
llvm-svn: 325400
Summary:
- Makes code more in line with LLVM style (e.g. const char * -> StringRef)
- Do not use formatv since we can construct message just by `+`
- Replace some odd types such as `const StringRef` with more common type
- Do not use default arguments if they are not necessary

There seems to be no reason to collect this list of symbols.
Also fix a bug where --exclude-libs would apply to all symbols that
appear in an archive's symbol table, even if the relevant archive
member was not added to the link.

Newer versions of the gnu assembler produce a X86_64_PLT32 for
calls. There is a change under review in llvm to do the same, so update
the tests to not depend on it.
We can still produce a R_X86_64_PC32 with ".long foo - .".

This bug effected undefined symbols that were resolved by
existing defined symbols. We were skipping the signature
check in this case.

Now that we have R_ADDEND, UseSymVA was redundant. We only want to
write the symbol virtual address when using an expression other than
R_ADDEND.

There is some discussion as to the exact behaviour of combining ICF and
--symbol-ordering-file, but it seems beneficial to warn when attempting
to order the removed symbol regardless of the preferred approach.

Summary:
This follows up on r321889 where writing of Elf_Rel addends was partially
moved to RelocationBaseSection. This patch ensures that the addends are
always written to the output section when a input section uses RELA but the
output is REL.

Previously, we accidentally dropped STB_WEAK bit from an undefined symbol
if there is a lazy object symbol with the same name. That caused a
compatibility issue with GNU gold.

Even though it doesn't make sense, there seems to be multiple programs
in the wild that create PC-relative relocations in non-ALLOC sections.
I believe this is caused by the negligence of GNU linkers to not report
any errors for such relocations.
Currently, lld emits warnings against such relocations and exits.
So, you cannot link any program that contains wrong relocations until
you fix an issue in a program that generates wrong ELF files. It's often
impractical to fix a program because it's not always easy.
This patch relaxes the error checking and emit a warning instead.

When we are emitting a relocatable output, we should keep the original
symbol name including "@" part. Previously, we drop that part unconditionally
which resulted in dropping versions from symbols.

This was causing GCC builds with fail with:
Symbols.h:240:3: error: static assertion failed: Symbol types must be
trivially destructible
static_assert(std::is_trivially_destructible<T>(
The reason this is a gcc-only failure is that OptionalStorage has
as specialization for POD types that isn't built under GCC.
