Cut off the version suffix (e.g. @GLIBC_2.2.5 etc.) from automatic
generated event name. This fixes wildcard event adding like below case;
=====
# perf probe -x /lib64/libc-2.25.so malloc*
Internal error: "malloc_get_state@GLIBC_2" is wrong event name.
Error: Failed to add events.
=====
This failure was caused by a versioned suffix symbol.
With this fix, perf probe automatically cuts the suffix after @ as
below.
=====
# ./perf probe -x /lib64/libc-2.25.so malloc*
Added new events:
probe_libc:malloc_printerr (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_consolidate (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_check (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_hook_ini (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_trim (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_usable_size (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_stats (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_info (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:mallochook (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_get_state (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_set_state (on malloc* in /usr/lib64/libc-2.25.so)
You can now use it in all perf tools, such as:
perf record -e probe_libc:malloc_set_state -aR sleep 1
