Subject: remove useless infinite loop from end of exit function
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;ds=sidebyside;h=5cc187215681c2fc1563ad5136c389249aa3f70e;p=musl

remove useless infinite loop from end of exit function

this was originally added as a cheap but portable way to quell
warnings about reaching the end of a function that does not return,
but since _Exit is marked _Noreturn, it's not needed. removing it
makes the call to _Exit into a tail call and shaves off a few bytes of
code from minimal static programs.
