Subject: How to translate from user space symbol name to address?

Hi,


usymname can be used to translate address to symbol name, but I can't find
an easy way to translate symbol name to address.

I can get the ubacktrace and translate the addresses to symbols one by one,
and try to find the relationship between the symbol and the address, but
it's a bit tricky I think.


In systemtap source code, tapset.cxx do get address for probed symbols, is
it possible to get symbol address during runtime?


The reason why I want to translate a symbol to an address is , I want to
strip part of the stack for readability.

Any clue is appreciated


Thanks

Yibin
