perf probe: Support a special SDT probe format
Support a special SDT probe format which can omit the '%' prefix only if
the SDT group name starts with "sdt_". So, for example both of
"%sdt_libc:setjump" and "sdt_libc:setjump" are acceptable for perf probe
--add.
E.g. without this:
# perf probe -a sdt_libc:setjmp
Semantic error :There is non-digit char in line number.
...
With this:
# perf probe -a sdt_libc:setjmp
Added new event:
sdt_libc:setjmp (on %setjmp in /usr/lib64/libc-2.20.so)
You can now use it in all perf tools, such as:
perf record -e sdt_libc:setjmp -aR sleep 1
