Follow-up to r371983. Referring to "this program" in the description of the --version option in the documentation isn't exactly correct, because the docs are not part of the program, and so "this program" doesn't really refer to anything. This patch brings the other users of this terminology into line with the new updates to llvm-size and llvm-strings.

llvm-objdump - LLVM's object file dumper
|
|
========================================
|
|
|
|
.. program:: llvm-objdump
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-objdump` [*commands*] [*options*] [*filenames...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The :program:`llvm-objdump` utility prints the contents of object files and
|
|
final linked images named on the command line. If no file name is specified,
|
|
:program:`llvm-objdump` will attempt to read from *a.out*. If *-* is used as a
|
|
file name, :program:`llvm-objdump` will process a file on its standard input
|
|
stream.
|
|
|
|
