George Rimar 0974688a42 [yaml2obj] - Allow setting st_value explicitly for Symbol.
In some cases it is useful to explicitly set symbol's st_name value.
For example, I am using it in a patch for LLD to remove the broken
binary from a test case and replace it with a YAML test.

George Rimar 6da44ad75d [yaml2obj][obj2yaml] - Change how symbol's binding is descibed when parsing/dumping.
Currently, YAML has the following syntax for describing the symbols:

Symbols:
  Local:
    LocalSymbol1:
    ...
    LocalSymbol2:
    ...
  ...
  Global:
    GlobalSymbol1:
  ...
  Weak:
  ...
  GNUUnique:

I.e. symbols are grouped by their bindings. That is not very convenient,
because:

It does not allow to set a custom binding, what can be useful for producing
broken/special outputs for test cases. Adding a new binding would require to
change a syntax (what we observed when added GNUUnique recently).

It does not allow to change the order of the symbols in .symtab/.dynsym,
i.e. currently all Local symbols are placed first, then Global, Weak and GNUUnique
are following, but we are not able to change the order.

It is not consistent. Binding is just one of the properties of the symbol,
we do not group them by other properties.

It makes the code more complex that it can be. This patch shows it can be simplified
with the change performed.

The patch changes the syntax to just:

Symbols:
  Symbol1:
  ...
  Symbol2:
  ...
...

With that, we are able to work with the binding field just like with any other symbol property.

James Henderson b10f48bbb4 [yaml2obj]Allow explicit setting of p_filesz, p_memsz, and p_offset
yaml2obj currently derives the p_filesz, p_memsz, and p_offset values of
program headers from their sections. This makes writing tests for
certain formats more complex, and sometimes impossible. This patch
allows setting these fields explicitly, overriding the default value,
when relevant.

James Henderson fd99780c09 [yaml2obj]Re-allow dynamic sections to have raw content
Recently, support was added to yaml2obj to allow dynamic sections to
have a list of entries, to make it easier to write tests with dynamic
sections. However, this change also removed the ability to provide
custom contents to the dynamic section, making it hard to test
malformed contents (e.g. because the section is not a valid size to
contain an array of entries). This change reinstates this. An error is
emitted if raw content and dynamic entries are both specified.

James Henderson 67bdfb0a59 [yaml2obj]Allow symbol Index field to take values lower than SHN_LORESERVE
In order to test tool handling of invalid section indexes, I need to
create an object containing such an invalid section index. I could
create a hex-edited binary, but having the ability to use yaml2obj is
preferable. Prior to this change, yaml2obj would reject any explicit
section indexes less than SHN_LORESERVE. This patch changes it to allow
any value.

I had to change the test to use llvm-readelf instead of llvm-readobj,
because llvm-readobj does not like invalid section indexes. I've also
expanded the test to show that the most common SHN_* values are accepted
(SHN_UNDEF, SHN_ABS, SHN_COMMON).

James Henderson d82914c8d2 [yaml2obj][obj2yaml] Remove section type range markers from allowed mappings and support hex values
yaml2obj/obj2yaml previously supported SHT_LOOS, SHT_HIOS, and
SHT_LOPROC for section types. These are simply values that delineate a
range and don't really make sense as valid values. For example if a
section has type value 0x70000000, obj2yaml shouldn't print this value
as SHT_LOPROC. Additionally, this was missing the three other range
markers (SHT_HIPROC, SHT_LOUSER and SHT_HIUSER).

This change removes these three range markers. It also adds support for
specifying the type as an integer, to allow section types that LLVM
doesn't know about.

Fix:
Replace

with
assert(IO.getContext() && "The IO context is not initialized");
(this was introduced in r354329, where I tried to quickfix the darwin BB

Original commit message:

The section is described here:
https://refspecs.linuxfoundation.org/LSB_1.3.0/gLSB/gLSB/symverrqmts.html

Patch just teaches obj2yaml/yaml2obj to dump and parse such sections.

We did the finalization of string tables very late,
and I had to move the logic to make it a bit earlier.
That was needed in this patch since .gnu.version_r adds strings to .dynstr.
This might also be useful for implementing other special sections.

Everything else changed in this patch seems to be straightforward.

George Rimar b87ea73706 [yaml2obj/obj2yaml] - Move `Info` field out from `Section` class.
ELFYAML.h contains a `Section` class which is a base for a few other
sections classes that are used for mapping different section types.
`Section` has a `StringRef Info` field used for storing sh_info.

At the same time, sh_info has very different meanings for sections and
cannot be processed in a similar way generally,
for example ELFDumper does not handle it in `dumpCommonSection`
but do that in `dumpGroup` and `dumpCommonRelocationSection` respectively.

At this moment, we have and handle it as a string, because that was possible for
the current use case. But also it can simply be a number:
For SHT_GNU_verdef is "The number of version definitions within the section."

The patch moves `Info` field out to be able to have it as a number. 
With that change, each class will be able to decide what type and purpose
of the sh_info field it wants to use.

I also had to edit 2 test cases. This is because patch fixes a bug. Previously we 
accepted yaml files with Info fields for all sections (for example, for SHT_DYNSYM too).
But we do not handle it and the resulting objects had zero sh_info fields set for
such sections. Now it is accepted only for sections that supports it.

We understand that people may be surprised that we're moving the header

Essentially, all code in the project is now made available by the LLVM

Saleem Abdulrasool b36fbbc3ec CodeGen: support an extension to pass linker options on ELF
Introduce an extension to support passing linker options to the linker.
These would be ignored by older linkers, but newer linkers which support
this feature would be able to process the linker.

Emit a special discarded section `.linker-option`.  The content of this
section is a pair of strings (key, value).  The key is a type identifier for
the parameter.  This allows for an argument free parameter that will be
processed by the linker with the value being the parameter.  As an example,
`lib` identifies a library to be linked against, traditionally the `-l`
argument for Unix-based linkers with the parameter being the library name.

Thanks to James Henderson, Cary Coutant, Rafael Espinolda, Sean Silva
for the valuable discussion on the design of this feature.

Jake Ehrlich 03aeeb09c5 [yaml2obj][ELF] Add support for setting alignment in program headers
Sometimes program headers have larger alignments than any of the
sections they contain. Currently yaml2obj can't produce such files. A
bug recently appeared in llvm-objcopy that failed in such a case. I'd
like to be able to add tests to llvm-objcopy for such cases.

This change adds an optional alignment parameter to program headers that
will be used instead of calculating the alignment.

Peter Collingbourne 689e6c052e llvm-readobj: Add support for reading relocations in the Android packed format.
This is in preparation for testing lld's upcoming relocation packing
feature (D39152). I have verified that this implementation correctly
unpacks the relocations from a Chromium DSO built with gold and the
Android relocation packer for ARM32 and ARM64.
