New gdbarch functions: dtrace_parse_probe_argument, dtrace_probe_is_enabled, dtrace_enable_probe, dtrace_disable_probe.
This patch adds several gdbarch functions (along with the corresponding predicates): `dtrace_parse_probe_argument', `dtrace_probe_is_enabled', `dtrace_enable_probe' and `dtrace_disable_probe'. These functions will be implemented by target-specific code, and called from the DTrace probes implementation in order to calculate the value of probe arguments, and manipulate is-enabled probes. gdb/ChangeLog: 2015-02-17 Jose E. Marchesi <jose.marchesi@oracle.com> * gdbarch.sh (dtrace_parse_probe_argument): New. (dtrace_probe_is_enabled): Likewise. (dtrace_enable_probe): Likewise. (dtrace_disable_probe): Likewise. * gdbarch.c: Regenerate. * gdbarch.h: Regenerate.
