Jordan Rupprecht d884fbde2a [llvm-readelf] Fix core note descriptions
Summary:
Core files have different descriptions for note values. llvm-readelf currently prints the generic note type, which is wrong when using it to read a core file.

To verify the constants/strings, see:
Values: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=include/elf/common.h;h=75c4fb7e9d7c0f780d635ac305f579546b7b071b;hb=HEAD#l571
Strings: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=binutils/readelf.c;h=c31a5c1266b7bb62a485895b01b49e1f832ade35;hb=HEAD#l16881

Note: this does not handle printing the note data for NT_FILE, it just fixes the descriptions.

Peter Smith e314a128a9 [AARCH64] Switch relocations R_AARCH64_TLS_TPREL64 and R_AARCH64_DTPMOD64
The ELF for the Arm 64-bit Architecture document originally specified
R_AARCH64_TLS_DTPREL64 = 0x404
R_AARCH64_TLS_DTPMOD64 = 0x405

LLVM correctly followed the document. Unfortunately in binutils these
two codes were reversed:
R_AARCH64_TLS_DTPMOD64 = 0x404
R_AARCH64_TLS_DTPREL64 = 0x405
Given that binaries had shipped this change has become the defacto standard
interpretation of these relocation codes for any toolchain that wanted to
remain compatible with GNU.

To recognize this the latest version of the ABI document has renamed
the relocations to R_AARCH64_TLS_IMPDEF1 and R_AARCH64_TLS_IMPDEF2
permitting a toolchain to choose between the two relocation types, and
recommending that toolchains follow the GNU interpretation for maximum
compatibility.

Given that upstream llvm has never implemented the standard TLS model for
AArch64 so we have no binary legacy, synchronize with GCC so that we don't
create incompatible objects in the future. So far the only visible change
is in llvm-readobj as it can decode these relocations. Tthis change will
mean that llvm-readobj decodes the same way as GNU readelf.

George Rimar cb487e9b44 [Object/llvm-readobj] - Cleanup testing of the dynamic objects.
This patch touches a few test cases:

It removes dtflags.elf-x86-64 binary and elf-dtflags.test.
elf-dtflags.test is excessive because we have the
elf-dynamic-tags.test which test all non-machine specific tags.

It removes testing of --dynamic-table from test\Object\readobj-shared-object.test
(we have the elf-dynamic-tags.test for that), and simplifies this test case.

It moves testing of the headers from readobj-shared-object.test
to elf-file-headers.test.

Adds test/tools/llvm-readobj/elf-file-types.test and test/tools/llvm-readobj/elf-loadname.test.

It opens road for removing the readobj-shared-object.test completely soon.

1) `-x foo` currently dumps one `foo`. This change makes it dump all `foo`.

   In addition, if foo has section index 9, `-x foo -x 9` dumps `foo` once.
3) Give a warning instead of an error if `foo` does not exist.

The new behaviors match GNU readelf.

Also, print a new line as a separator between two section dumps.

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.

because found they are used in other tests. 
* I was unable to convert relocs.obj.elf-ppc64, because obj2yaml hangs on this file for me.
* I was unable to convert relocs.obj.macho-arm, relocs.obj.macho-i386 and relocs.obj.macho-x86_64
because the output produced by obj2yaml does not seem to be correct.
* Because of the above I did not remove the script for creating all
of those objects: test\tools\llvm-readobj\Inputs\relocs.py

George Rimar c372f41c18 [llvm-readobj/llvm-readelf] - Implement GNU style dumper of the SHT_GNU_verdef section.
It was not implemented yet, we had only LLVM style dumper implemented.

George Rimar 5b363c14d7 [llvm-readobj] - Repair the test case.
I forgot to change the test tag in r361932.
Now it is fixed.

George Rimar 8ac7b2d07b [llvm-readelf] - Allow dumping of the .dynamic section even if there is no PT_DYNAMIC header.
It is now possible after D61937 was landed and was discussed
in it's review comments. It is not consistent with GNU, which
does not output .dynamic section content in this case for
no visible reason.

George Rimar 65dde1e0db [llvm-readobj/llvm-readelf] - Simplify the elf-versioninfo.test test case.
This removes 2 precompiled objects from the test case and replaces
them with a single YAML. That allowed to simplify and clean up the test,
remove excessive checks.

Hans Wennborg 5b86163f62 Fix some llvm-readelf tests after r361633
They were failing on 32-bit Windows. In the cases where I've changed
test expectations, I've checked that they match the output of GNU
readelf.
