|\ | | | | | | | | | | | | | | | | | | | | | | * 'master' of ssh://sources.redhat.com/git/systemtap: PR10719 part 1: Partial constant folding Simplify null_statement construction Fixed PR 11269 by properly handling mmap syscall 'fd' argument. Removed rvalue operator check. PR 10690 (partial fix). Handle '.=' operator in procfs probes. Conflicts: tapsets.h

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * tapsets.h (var_expanding_visitor): Add 'valid_ops' and 'op' member variables. * tapsets.cxx (var_expanding_visitor::var_expanding_visitor): Set 'valid_ops' to '='. By default, var_expanding_visitor classes only handle the '=' operator. (var_expanding_visitor::visit_assignment): Remember what operator we're handling. When an operator is found that isn't in the 'valid_ops' set, error. * tapset-procfs.cxx (procfs_var_expanding_visitor::procfs_var_expanding_visitor): Add '.=' to the 'valid_ops' set. (procfs_var_expanding_visitor::visit_target_symbol): Handle the '.=' operator when the target variable is an lvalue.

* Separate built-in timer tapsetsJosh Stone2009-05-061-2/+17
| | | | | | All of the timer.* tapsets are now built and handled in their own tapset-timers.cxx, as the first step of many to pare down the current monolithic tapsets.cxx.
* PR 9941: Add predicate function callback to check for an early abortRajan Arora2009-04-221-0/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Probe registration rework. Offline dwarf processing for better cross-instrumentation. * elaborate.h (derived_probe): Remove registration-related code generation API. Add new function sole_location(). (derived_probe_group): Reworked this and associated classes. * session.h (systemntap_session): Create individual per-category derived_probe_groups. * elaborate.cxx (derived_probe_group): Reworked. (alias_derived_probe): Switch to new derived_probe API. (semantic_pass_symbols): Ditto. * translate.cxx (mapvar init): Check for array initialization error. (emit_module_init): Handle such failures, at least in theory. (emit_module_exit): Switch to new derived_probe_group API. Call cpu_relax() during shutdown busywait. (emit_common_header): Elide context variables for elided handler fns. (c_unparser::emit_probe): Implement new, improved duplicate elimination technique for probe handlers. Leave two older ones behind as compile options for education. * tapsets.cxx (*): Reworked all probe registration code, moving it from derived_probes into derived_probe_groups. Shrunk output code. Temporarily disabled probe timing and perfmon/mark probes. (dwflpp): Use offline reporting, so that module matching and relocation is performed at run time. (dwarf_query): Remove flavour logic, now supplanted by other duplicate elimination code. (dwarf_derived_probe): Reworked construction, centralized module/section/offset computations. * tapsets.h (all_session_groups): New little helper. * main.cxx (main): For pass-2 message, print number of embeds too. * systemtap.spec.in: Add a "BuildRequires: dejagnu" for make check. * configure.ac: Bump version to 0.5.11. * configure: Regenerated.
