Subject: Workaround 'function nested_sp is never used' cppcheck style warning
X-Git-Tag: v7.6.8~89
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=68e8c9d56f657e80816781a4a331e34919e03a4d;p=gc

Workaround 'function nested_sp is never used' cppcheck style warning

The warning should not be produced by cppcheck as nested_sp is assigned
to nested_sp_fn variable.

* tools/setjmp_t.c [CPPCHECK] (main): Call nested_sp() directly; add
comment.
