| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * parse.cxx (parser::parser): Added initializer for 'context' member variable. (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. Calls to the hexstring() function were converted to sprintf() calls. * testsuite/semok/eleven.stp: Ditto. * testsuite/buildok/seventeen.stp: Calls to log()/hexstring() were converted to a call to printf(). * testsuite/semko/nineteen.stp: Ditto. * testsuite/parseok/three.stp: Because keywords are reserved, a variable named 'string' was renamed to 'str'. * testsuite/parseok/two.stp: Because keywords are reserved, a variable named 'global' was renamed to 'gbl'. * testsuite/transko/two.stp: Because the parser now checks for 'next' and 'return' statement context, a 'next' statement was removed from a function and a 'return' statement was removed from a probe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | * conversions.stp (hexstring, string): Removed functions. Because of parser changes, "string" is now a reserved word and cannot be a function name. Use 'sprintf("0x%x", num)' to replace hexstring() and either 'sprint(num)' or 'sprintf("%d", num)' to replace string(). * syscalls.stp (syscall.accept, syscall.alarm, syscall.close, syscall.dup, syscall.epoll_create, syscall.exit, syscall.fchdir, syscall.fdatasync, syscall.fsync, syscall.getsid) Changed 'string()' calls to 'sprint()' calls. * syscalls2.stp (syscall.sched_get_priority_max, syscall.sched_get_priority_min, syscall.sched_getscheduler, syscall.setfsgid, syscall.setfsgid16, syscall.setfsuid, syscall.setfsuid16, syscall.setgid, syscall.setgid16, syscall.setuid, syscall.setuid16, syscall.ssetmask, syscall.timer_delete, syscall.timer_getoverrun): Ditto. * i686/syscalls.stp (syscall.iopl, syscall.rt_sigreturn, syscall.sigreturn): Ditto. * ppc64/syscalls.stp (syscall.ppc64_personality): Ditto. * x86_64/syscalls.stp (kernel.syscall.iopl, kernel.syscall.umask): Ditto. * test/ctostp.sh: Uses 'sprint()' instead of 'string()' in generated systemtap code.
