Cyndy Ishida 5f865ecf06 [TextAPI] Update reader to be supported by lib/Object
Summary:
To be able to use the TextAPI/Reader for tbd file consumption (by libObject)
it gets passed a MemoryBufferRef which isn't castable to MemoryBuffer.
Updated the tests to expect that input as well.

Juergen Ributzka b978c51ce4 [TextAPI] Fix & Add tests for tbd files version 3.
- There was a simple typo in TextStub code that prevented version 3 files to be read.
- Included a version 3 unit test to handle the differences in the format.
- Also a typo in Error.h inside the comments.

Fangrui Song 27ed1c5bb8 [YAMLIO] Remove trailing spaces when outputting maps
llvm::yaml::Output::paddedKey unconditionally outputs spaces, which
are superfluous if the value to be dumped is a sequence or map.
Change `bool NeedsNewLine` to `StringRef Padding` so that it can be
overridden to `\n` if the value is a sequence or map.

An empty map/sequence is special. It is printed as `{}` or `[]` without
a newline, while a non-empty map/sequence follows a newline. To handle
this distinction, add another variable `PaddingBeforeContainer` and does
the special handling in endMapping/endSequence.

Juergen Ributzka 875565e559 [TextAPI] Prefix all architecture enums to fix the build on i386.
Summary: This changes the Architecture enum to use a prefix (AK_) to prevent the
preprocessor from replacing i386 with 1 when building llvm/clang for i386.

Juergen Ributzka 32cb594177 [TextAPI] TBD Reader/Writer
Add basic infrastructure for reading and writting TBD files (version 1 - 3).

The TextAPI library is not used by anything yet (besides the unit tests). Tool
support will be added in a separate commit.

The TBD format is currently documented in the implementation file (TextStub.cpp).

https://reviews.llvm.org/D53945

Update: This contains changes to fix issues discovered by the bots:
 - add parentheses to silence warnings.
 - rename variables
 - use PlatformType from BinaryFormat
 - Trying if switching from a vector to an array will appeas the bots.
 - Replace the tuple with a struct to work around an explicit constructor bug.
 - This fixes an issue where we were leaking the YAML document if there was a
   parsing error.

Updated the license information in all files.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

build.

See https://logs.chromium.org/logs/chromium/bb/client.wasm.llvm/linux/37764/+/recipes/steps/LLVM_regression_tests/0/stdout

What is more it seems that overriding these traits for core types
(including std::string) is not supported/recommend by YAMLTraits.h.
See line 1918 which has the assertion:
 "only use LLVM_YAML_IS_SEQUENCE_VECTOR for types you control"

Armando Montanez 1e4b3709bb [llvm-tapi] initial commit, supports ELF text stubs
http://lists.llvm.org/pipermail/llvm-dev/2018-September/126472.html

TextAPI is a library and accompanying tool that allows conversion between binary shared object stubs and textual counterparts. The motivations and uses cases for this are explained thoroughly in the llvm-dev proposal [1]. This initial commit proposes a potential structure for the TAPI library, also including support for reading/writing text-based ELF stubs (.tbe) in addition to preliminary support for reading binary ELF files. The goal for this patch is to ensure the project architecture appropriately welcomes integration of Mach-O stubbing from Apple's TAPI [2].

Added:

 - TextAPI library
 - .tbe read support
 - .tbe write (to raw_ostream) support
