| | | | | | | | | | | | | | | | | | | | | | | | PR 4146 * tapsets.cxx (common_probe_entryfn_prologue): Added 'interruptible' parameter. If a probe is interruptible, interrupts are not disabled while the probe executes. Preemption is disabled however. Interruptible parameter defaults to false. (common_probe_entryfn_epilogue): Ditto. (be_derived_probe_group::emit_module_decl): Uses new 'interruptible' parameter to mark begin/end probes as interruptible. (probe_derived_probe_group::emit_module): Initialize 'actionremaining' with MAXACTION instead of initializing 'actioncount' with 0. * translate.cxx (emit_common_header): Renamed 'actioncount' to 'actionremaining'. Turned logic around to initialize actionremaining to MAXACTION or MAXACTION_INTERRUPTIBLE then decrement it as actions occur. (translate_pass): Added MAXACTION_INTERRUPTIBLE initialization. * translate.h: Removed outdated comment portion. * stap.1.in: Documented MAXACTION_INTERRUPTIBLE. * NEWS: Added note about begin/end probes being run with interrupts enabled.
