Hi, I've made a patch to address (b), (c), (d). I didn't adjust takewhile. I chose to do it differently since target-specific params in both invoke.texi and --help=params have to be ignored. The downside of this patch is that the script won't complain if someone adds a target-specific param and doesn't document it. What do you think? Cheers, Filip -- 8< -- contrib/check-params-in-docs.py is a script that checks that all options reported with gcc --help=params are in gcc/doc/invoke.texi and vice versa. gcc/doc/invoke.texi lists target-specific params but gcc --help=params doesn't. This meant that the script would mistakenly complain about parms missing from --help=params. Previously, the script was just set to ignore aarch64 and gcn params which solved this issue only for x86. This patch sets the script to ignore all target-specific params. contrib/ChangeLog: * check-params-in-docs.py: Ignore target specific params.
