Subject: profil-counter: Add missing SIGINFO case
X-Git-Tag: glibc-2.33~159
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=53432762ac2ff24794089e2c767b976e54c2dc0a;p=thirdparty%2Fglibc.git

profil-counter: Add missing SIGINFO case

When SA_SIGINFO is available, sysdeps/posix/s?profil.c use it, so we have to
fix the __profil_counter function accordingly, using sigcontextinfo.h's
sigcontext_get_pc.
