Subject: static functions have a need for mangled name debug information too.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=43443de48bd7f69bba033566abd9ca33abea6d67;p=clang

static functions have a need for mangled name debug information too.
The mangler doesn't like non-prototyped functions so only use a mangled
name for prototyped functions.
