| | | | | | | | | * tapset/context-symbols.stp (syname, symdata): Pass NULL for kernel address. * tapset/ucontext-symbols.stp: New file defining usymname and usymdata. * testsuite/systemtap.context/usymbols.exp: Use usymname, remove STP_NEED_VMA_TRACKER hack. * testsuite/buildok/usymdata.stp: New test. * testsuite/buildok/usymname.stp: Likewise.
* PR6580: Implement symname, symdata and modname context functions.Mark Wielaard2009-04-021-1/+1
| | | | | | | | | | | | | | | | | | This adds a couple of the suggested context/stack revamp functions from PR6580. In particular it replaces the symbolname() function that sneaked in with the pr6866 branch merge with the suggested symname(). * runtime/sym.c (_stp_mod_sec_lookup): Make section optional. (_stp_symbol_snprint): Provide a way to get optional module info. * tapset/context-symbols.stp: Replace symbolname() with symname(), add modname() and symdata(). (probemod): Implement pc based fallback. * tapset/context-unwind.stp (caller): Adjust for _stp_symbol_snprint change. * testsuite/systemtap.context/usymbols.exp: Use new symname. * testsuite/buildok/modname.stp: New test. * testsuite/buildok/symdata.stp: Likewise. * testsuite/buildok/symname.stp: Likewise.
