George Rimar 0aecabae14 Revert "Revert r363377: [yaml2obj] - Allow setting custom section types for implicit sections."
LLD test case will be fixed in a following commit.

Original commit message:

[yaml2obj] - Allow setting custom section types for implicit sections.

We were hardcoding the final section type for sections that
are usually implicit. The patch fixes that.

This also fixes a few issues in existent test cases and removes
one precompiled object.

James Henderson 891cdaab7a [docs][llvm-dwarfdump] Make the --show-parents and --show-children help text and docs more consistent and correct
The docs and help text for --show-parents and --show-children were a bit
inconsistent. The help text claimed they had an effect when "=<offset>"
was used, whereas the doc said it had an effect when "--find" or
"--name" were used. This change changes the doc to mention "=<offset>"
and removes this reference from the help text, to avoid having a very
long description in the help text (it still says "when selectively
printing entries").

George Rimar d6df7ded6e [llvm-readobj] - Do not fail to dump the object which has wrong type of .shstrtab.
Imagine we have object that has .shstrtab with type != SHT_STRTAB.
In this case, we fail to dump the object, though GNU readelf dumps it without
any issues and warnings.

This patch fixes that. It adds a code to ELFDumper.cpp which is based on the implementation of getSectionName from the ELF.h:

https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Object/ELF.h#L608
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Object/ELF.h#L431
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Object/ELF.h#L539

The difference is that all non critical errors are ommitted what allows us to
improve the dumping on a tool side. Also, this opens a road for a follow-up that
should allow us to dump the section headers, but drop the section names in case if .shstrtab is completely absent and/or broken.

there is no reason to disallow setting the custom address

One change is now any volatile access is treated as capturing. The

removing volatile in the lifetime capture test.

Ben Dunbobbin 564d248ec2 [ThinLTO]LTO]Legacy] Fix dependent libraries support by adding querying of the IRSymtab
Dependent libraries support for the legacy api was committed in a
broken state (see: https://reviews.llvm.org/D60274). This was missed
due to the painful nature of having to integrate the changes into a
linker in order to test. This change implements support for dependent
libraries in the legacy LTO api:

- I have removed the current api function, which returns a single
string, and   added functions to access each dependent library
specifier individually.

- To reduce the testing pain, I have made the api functions as thin as
possible to   maximize coverage from llvm-lto.

- When doing ThinLTO the system linker will load the modules lazily
when scanning   the input files. Unfortunately, when modules are
lazily loaded there is no access   to module level named metadata. To
fix this I have added api functions that allow   querying the IRSymtab
for the dependent libraries. I hope to expand the api in the   future
so that, eventually, all the information needed by a client linker
during   scan can be retrieved from the IRSymtab.

There was a typo in the --ignore-case help text that was copied into the
llvm-dwarfdump command-guide. Additionally, this patch simplifies the
wording, since it was unnecessarily verbose: the switch applies for
searching in general and doesn't need explicitly stating different
search modes (which might go out-of-date as options are added or
removed).

Nico Weber dd6019526d Let writeWindowsResourceCOFF() take a TimeStamp parameter
For lld, pass in Config->Timestamp (which is set based on lld's
/timestamp: and /Brepro flags). Since the writeWindowsResourceCOFF()
data is only used in-memory by LLD and the obj's timestamp isn't used
for anything in the output, this doesn't change behavior.

For llvm-cvtres, add an optional /timestamp: parameter, and use the
current behavior of calling time() if the parameter is not passed in.

This doesn't really change observable behavior (unless someone passes
/timestamp: to llvm-cvtres, which wasn't possible before), but it
removes the last unqualified call to time() from llvm/lib, which seems
like a good thing.

Jordan Rupprecht f8f9d65f85 [llvm-objcopy] Fix SHT_GROUP ordering.
Summary:
When llvm-objcopy sorts sections during finalization, it only sorts based on the offset, which can cause the group section to come after the sections it contains. This causes link failures when using gold to link objects created by llvm-objcopy.

Fix this for now by copying GNU objcopy's behavior of placing SHT_GROUP sections first. In the future, we may want to remove this sorting entirely to more closely preserve the input file layout.

This fixes https://bugs.llvm.org/show_bug.cgi?id=42052.

George Rimar 379aa18a39 [yaml2obj] - Do not assert when .dynsym is specified explicitly, but .dynstr is not present.
We have a code in buildSectionIndex() that adds implicit sections:

// Add special sections after input sections, if necessary.
for (StringRef Name : implicitSectionNames())
  if (SN2I.addName(Name, SecNo)) {
    // Account for this section, since it wasn't in the Doc
    ++SecNo;

The problem arises when .dynsym is specified explicitly and no
DynamicSymbols is used. In that case, we do not add
.dynstr implicitly and will assert later when will try to set Link
for .dynsym.

Seems, in this case, reasonable behavior is to allow Link field to be zero.

This implements the functionality described in

- Reads the section headers using the ELF header at file offset 0;
- If extracting a loadable partition:
  - Finds the section containing the required partition ELF header by looking it up in the section table;
  - Reads the ELF and program headers from the section.
- If extracting the main partition:
  - Reads the ELF and program headers from file offset 0.
- Filters the section table according to which sections are in the program headers that it read:
  - If ParentSegment != nullptr or section is not SHF_ALLOC, then it goes in.
  - Sections containing partition ELF headers or program headers are excluded as there are no headers for these in ordinary ELF files.
