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.

(tt2str): Added support for new tok_keyword type. (operator <<): Ignores keyword content when outputting error message. (lexer::scan): Recognizes keywords, such as 'probe', 'global', 'function', etc. and classifies them as type 'tok_keyword'. This causes keywords to become reserved so they cannot be used for function names, variable names, etc. (parser::parse): Changed tok_identifier to tok_keyword when looking for "probe", "global", or "function". Also sets context member variable which remembers if we're in probe, global, function, or embedded context. (parser::parse_probe, parser::parse_statement) (parser::parse_global, parser::parse_functiondecl) (parser::parse_if_statement, parser::parse_delete_statement) (parser::parse_break_statement, parser::parse_continue_statement) (parser::parse_for_loop, parser::parse_while_loop) (parser::parse_foreach_loop, parser::parse_array_in): Looks for tok_keyword instead of tok_identifier. (parser::parse_probe_point): Allows keywords as part of a probe name, since "return" and "function" are keywords. (parser::parse_return_statement): Looks for tok_keyword instead of tok_identifier. Make sure we're in function context. (parser::parse_next_statement): Looks for tok_keyword instead of tok_identifier. Make sure we're in probe context. * parse.h: Added parse_context enum. Added 'tok_keyword' to token_type enum. Added parse_context 'context' member variable to parser class. * stap.1.in: Because the string() function has been removed, the 'string()' function reference has been changed to a 'sprint()' function reference. * stapex.5.in: Ditto. * stapfuncs.5.in: The description of the string() and hexstring() functions has been removed. * testsuite/buildok/context_test.stp: Calls to the string() function were converted to sprint() function calls. * testsuite/buildok/fifteen.stp: Ditto. * testsuite/buildok/nineteen.stp: Ditto. * testsuite/buildok/process_test.stp: Ditto. * testsuite/buildok/task_test.stp: Ditto. * testsuite/buildok/timestamp.stp: Ditto. * testsuite/buildok/twentyone.stp: Ditto. * testsuite/semok/args.stp: Ditto. * testsuite/semok/seven.stp: Ditto. * testsuite/buildok/fourteen.stp: Calls to log()/string() were converted to a call to printf(). * testsuite/buildok/sixteen.stp: Ditto. * testsuite/buildok/thirteen.stp: Ditto. * testsuite/buildok/twentythree.stp: Ditto. * testsuite/buildok/twentytwo.stp: Ditto. * testsuite/buildok/seven.stp: Calls to the string() function were converted to sprint() calls.
