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* translate.h: Removed outdated comment portion.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.
