PR 1144, 1379
* tapsets.cxx (emit_probe_prologue, _epilogue): New routines.
Call from existing derived_probe spots. Implement soft errors in
epilogue code. Implement reentrancy detection in prologue code.
(dwarf_derived_probe::emit_deregistration): Add kprobes layer
"nmissed" to skipped_count.
* translate.cxx (varlock): Use nsleep(TRYLOCKDELAY) in lock
contention loop.
(emit_module_exit): Report number of soft errors and skipped probes.
(emit_function, _probe): Add __restrict__ marker to context pointer.
(translate_pass): Define new MAXTRYLOCK, TRYLOCKDELAY, MAXERRORS,
MAXSKIPPED parameters.
* tapset/logging.stp (error): Don't stp_error, just set context state.
* stap.1.in, stapfuncs.5.in: Document soft errors.
* elaborate.h: Corresponding changes.
2006-01-03 Frank Ch. Eigler <fche@redhat.com>
* io.c (_stp_softerror): New function.
2006-01-03 Frank Ch. Eigler <fche@redhat.com>
