Subject: Remove unnecessary returns and unused variables in AIX.
X-Git-Tag: binutils-2_42~753
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d7ac0027a4419b85cd6db4c6fc84d287e34f84a9;p=thirdparty%2Fbinutils-gdb.git

Remove unnecessary returns and unused variables in AIX.

This is a patch to simplify the pd_activate () in aix-thread.c incase of a failure to start a thread session
, since pd_activate () now has return type void.

Also this patch fixes the shadow declarartion warning in sync-threadlists.
