From 9485b265e8a88c34c30467deee54e51299be73e1 Mon Sep 17 00:00:00 2001 From: James Henderson Date: Fri, 21 Jun 2019 11:49:20 +0000 Subject: [binutils] Add response file option to help and docs Many LLVM-based tools already support response files (i.e. files containing a list of options, specified with '@'). This change simply updates the documentation and help text for some of these tools to include it. I haven't attempted to fix all tools, just a selection that I am interested in. I've taken the opportunity to add some tests for --help behaviour, where they were missing. We could expand these tests, but I don't think that's within scope of this patch. This fixes https://bugs.llvm.org/show_bug.cgi?id=42233 and https://bugs.llvm.org/show_bug.cgi?id=42236.
