Hi Marcus, As per your comments in https://sourceware.org/ml/libc-ports/2013-09/msg00114.html, I have separated the patch that adds signal handler definitions for profiling. Cross tested with glibc testsuites on ARM V8 foundation model, with no regressions. Also please let me know, "_mcount" patch in https://sourceware.org/ml/libc-ports/2013-09/msg00090.html is good to go. Changelog: 2013-09-23 Venkataramanan Kumar * sysdeps/unix/sysv/linux/sigcontextinfo.h: New file if they are OK, can someone please commit it on my behalf. regards, Venkat.
