* runtime: print stp_alloc statistics in startup printkFrank Ch. Eigler2009-12-101-19/+12

* PR10650: markup some unprivileged-safe tapset functionsFrank Ch. Eigler2009-09-161-2/+10
| | | | | | | | | | | | | | | | | Add /* unprivileged */ to a variety of tapset embedded-c functions, together with uid-assertion-checking code as needed. This is only an initial set, and may need to grow or shrink after further testing. Prototyped-By: Dave Brolley <brolley@redhat.com> * runtime/runtime.h (is_myproc, assert_is_myproc): New macros. * runtime/addr-map.c (lookup_bad_addr): Reject if !is_myproc in unprivileged mode. * runtime/print.c (_stp_print_kernel_info): Add unprivileged mode info. * tapset/DEVGUIDE: Document /* pure */ and /* unprivileged */. * tapset/*.stp: Add /* unprivileged */ here and there, in questionable cases along with an assert_is_myproc().

* Use 'static' as much as possibleJosh Stone2009-01-281-8/+8
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
