Adds JSONScopedPrinter to llvm-readelf. It includes an empty JSONELFDumper class which will be used to override any LLVMELFDumper methods which utilize startLine() which JSONScopedPrinter cannot provide. This introduces a change where calls to llvm-readelf with non-ELF object files that specify --elf-output-style=GNU will now print file summary information where it previously didn't. Fixes previous Windows test failure which occured due to JSON escaping of '\' by not relying on LIT substitution. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D114225

|
|
===========================================
|
|
|
|
.. program:: llvm-readelf
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-readelf` [*options*] [*input...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
The :program:`llvm-readelf` tool displays low-level format-specific information
|
|
about one or more object files.
|
|
|
|
If ``input`` is "``-``", :program:`llvm-readelf` reads from standard
|
|
input. Otherwise, it will read from the specified ``filenames``.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
.. option:: --all, -a
|
|
|
|

|
|
format.

|
|
|
Display demangled symbol names in the output.
