a9d04d084c [readobj] Add functionality to dump relocations inside of binary blobs
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@257777 91177308-0d34-0410-b5e6-96231b3b80d8

51bb529b5b [codeview] Print relocations against code and data offset fields
These fields are almost always zero. However, there are relocations
against them, and we should print the relocation symbol with it as
SYM+0xNN.

294255bbe4 [CodeView] Add support for dumping binary annotations
Binary annotations are encoded along the lines of UTF-8 and ECI but with
a few minor differences.

The algorithm specified in "ECMA-335 CLI Section II.3.2 - Blobs and
Signatures" is used to compress binary annotations.  Signed binary
annotations are encoded like unsigned annotations except the sign bit is
rotated left to reduce the number of bits needed to be encoded.

13d3e2ec58 [codeview] Share more enums across the writer and the dumper
Moves some .def files into include/DebugInfo/CodeView.

Aslo remove a 'using namespace' directive from a header in readobj and
update the uses of the endian helper types to compensate.

fb30f09c13 [readobj] Expand CodeView dumping functionality
This rewrites and expands the existing codeview dumping functionality in
llvm-readobj using techniques similar to those in lib/Object. This defines a
number of new records and enums useful for reading memory mapped codeview
sections in COFF objects.

The dumper is intended as a testing tool for LLVM as it grows more codeview
output capabilities.

268709a810 Reapply r250906 with many suggested updates from Rafael Espindola.
The needed lld matching changes to be submitted immediately next,
but this revision will cause lld failures with this alone which is expected.

This removes the eating of the error in Archive::Child::getSize() when the characters
in the size field in the archive header for the member is not a number.  To do this we
have all of the needed methods return ErrorOr to push them up until we get out of lib.
Then the tools and can handle the error in whatever way is appropriate for that tool.

So the solution is to plumb all the ErrorOr stuff through everything that touches archives.
This include its iterators as one can create an Archive object but the first or any other
Child object may fail to be created due to a bad size field in its header.

Thanks to Lang Hames on the changes making child_iterator contain an
ErrorOr<Child> instead of a Child and the needed changes to ErrorOr.h to add
operator overloading for * and -> .

We don’t want to use llvm_unreachable() as it calls abort() and is produces a “crash”
and using report_fatal_error() to move the error checking will cause the program to
stop, neither of which are really correct in library code. There are still some uses of
these that should be cleaned up in this library code for other than the size field.

The test cases use archives with text files so one can see the non-digit character,
in this case a ‘%’, in the size field.

These changes will require corresponding changes to the lld project.  That will be
committed immediately after this change.  But this revision will cause lld failures
with this alone which is expected.

Also corrected the code where the size gets us to the “at the end of the archive”
which is OK but past the end of the archive will return object_error::parse_failed now.

in this case a ‘%’, in the size field.

0d34e64f73 Don't iterate over all sections in the ELFFile constructor.
With this we finally have an ELFFile that is O(1) to construct. This is helpful
for programs like lld which have to do their own section walk.

4d79d2fcbf Delete getDotSymtabSec.
Another step in avoiding iterating over all sections in the ELFFile constructor.

e84d8c12d5 Convert getSymbolSection to return an ErrorOr.
This function can actually fail since the symbol contains an index to the
section and that can be invalid.

310e6c3606 Don't look for a SHT_DYNSYM in the ELFFile's constructor.
Yet another step in not having it scan every section.
