Accept and ignore --wide/-W. In GNU readelf this switch is

In GNU readelf, the short option for --sections is upper-case -S.
Note that GNU uses lower-case -s to mean --symbols, while LLVM
uses -s to mean --sections and -t to mean --symbols (-t has yet a
different meaning in GNU). So command-line uses with -S can now
be compatible, but uses with -s or -t are still incompatible.

Main problem here was that SHF_COMPRESSED has the same value with

As far I understand xCore is a family of controllers and it that
means it's constant should be processed separately,
only if e_machine == EM_XCORE, otherwise llvm-readobj would output
different constants twice for compressed section:
Flags [
..
SHF_COMPRESSED (0x800)

XCORE_SHF_CP_SECTION (0x800)

what probably does not make sence if you're not working with xcore file.

This just checks that we emit all type records once, and then after
merging the type stream with no other type streams, we still emit every
kind of type record.
We could test the dumper output more closely, but that would make the
test very brittle. Currently we're just getting coverage.
llvm-svn: 269778
Summary:
This code is intended to be used as part of LLD's PDB writing. Until
that exists, this is exposed via llvm-readobj for testing purposes.
Type stream merging uses the following algorithm:
- Begin with a new empty stream, and a new empty hash table that maps
from type record contents to new type index.
- For each new type stream, maintain a map from source type index to
destination type index.
- For each record, copy it and rewrite its type indices to be valid in
the destination type stream.
- If the new type record is not already present in the destination
stream hash table, append it to the destination type stream, assign it
the next type index, and update the two hash tables.
- If the type record already exists in the destination stream, discard
it and update the type index map to forward the source type index to
the existing destination type index.

In a relocation target can take 3 basic forms
* A r_value in scattered relocations.
* A symbol in external relocations.
* A section is non-external relocations.
Have the dump reflect that. With this change we go from
CHECK-NEXT: Extern: 0
CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5)
CHECK-NEXT: Symbol: 0x2
CHECK-NEXT: Scattered: 0
To just
// CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5)
// CHECK-NEXT: Section: __data (2)
Since the relocation is with a section, we print the seciton name and don't
need to say that it is not scattered or external.

ARM64_RELOC_ADDEND and ARM_RELOC_PAIR.

The string data for string-valued build attributes were being unconditionally
uppercased. There is no mention in the ARM ABI addenda about case conventions,
so it's technically implementation defined as to whether the data are
capitialised in some way or not. However, there are good reasons not to
captialise the data.
* It's less work.
* Some vendors may legitimately have case-sensitive checks for these
attributes which would fail on LLVM generated object files.
* There could be locale issues with uppercasing.
The original reasons for uppercasing appear to have stemmed from an
old codesourcery toolchain behaviour, see
http://comments.gmane.org/gmane.comp.compilers.llvm.cvs/87133
This patch makes the object file emitted no longer captialise string
data, it encodes as seen in the assembly source.

This mostly entails adding relocations, however there are a couple of
changes to existing relocations:
1. R_AARCH64_NONE is defined to be zero rather than 256
R_AARCH64_NONE has been defined to be zero for a long time elsewhere
e.g. binutils and glibc since the submission of the AArch64 port in
2012 so this is required for compatibility.
2. R_AARCH64_TLSDESC_ADR_PAGE renamed to R_AARCH64_TLSDESC_ADR_PAGE21
I don't think there is any way for relocation names to leak out of LLVM
so this should not break anything.
Tested with check-all with no regressions.

It printed out base relocation table header as table entry.
This patch also makes llvm-readobj to not skip ABSOLUTE entries
becuase it was confusing.

We were a little lax in a few areas:
- We pretended that import libraries were like any old COFF file, they
are not. In fact, they aren't really COFF files at all, we should
probably grow some specialized functionality to handle them smarter.
- Our symbol iterators were more than happy to attempt to go past the
end of the symbol table if you had a symbol with a bad list of
auxiliary symbols.

Codeview line tables for functions in different sections refer to a common
STRING_TABLE_SUBSECTION for filenames.
This happens when building with -Gy or with inline functions with MSVC.

This patch defines a new iterator for the imported symbols.
Make a change to COFFDumper to use that iterator to print
out imported symbols and its ordinals.
llvm-svn: 218915
When the flag is given, the command prints out the COFF import table.
Currently only the import table directory will be printed.
I'm going to make another patch to print out the imported symbols.
The implementation of import directory entry iterator in
COFFObjectFile.cpp was buggy. This patch fixes that too.

Teach yaml2obj how to make a bigobj COFF file. Like the rest of LLVM,
we automatically decide whether or not to use regular COFF or bigobj
COFF on the fly depending on how many sections the resulting object
would have.
This ends the task of adding bigobj support to LLVM.
N.B. This was tested by forcing yaml2obj to be used in bigobj mode
regardless of the number of sections. While a dedicated test was
written, the smallest I could make it was 36 MB (!) of yaml and it still
took a significant amount of time to execute on a powerful machine.
