D68110 added --arch-specific (supported by GNU readelf) and made --arm-attributes an alias for it. The tests were later migrated to use --arch-specific. Note, llvm-readelf --arch-specific currently just uses llvm-readobj style output for ARM attributes. The readelf-style output is not implemented.

llvm-readelf - GNU-style LLVM Object Reader
|
|
===========================================
|
|
|
|
.. 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 "``-``" or omitted, :program:`llvm-readelf` reads from standard
|
|
input. Otherwise, it will read from the specified ``filenames``.
|
|
|
|
