| | | | | * systemtap.base/optim_voidstmt.stp: Add tests for various statement optimizations that we should now be eliding.

* New optimization to break up statements in void contexts.Josh Stone2008-06-182-19/+435
| | | | | | | | | | | | | | | | PR 6644 * elaborate.cxx (dead_stmtexpr_remover::visit_block): Flatten nested block statements into a single block. (dead_stmtexpr_remover::visit_if_statement): Remove the possibility of if_statements with a null thenblock. When an if lacks both then and else, either remove it completely or reduce it to a simple statment evaluating the condition. With an else and no then, invert the condition and else becomes then. (void_statement_reducer): New optimization visitor that breaks statements in void context into smaller pieces, to expose more optimization opportunities. (semantic_pass_opt5, semantic_pass_opt6): Bump opt5 to opt6, and create a new opt5 that runs through void_statement_reducer.

| |/ |/| | | | | | | | | | | | | | | | | 2008-06-17 David Smith <dsmith@redhat.com> * task_finder.c (__stp_utrace_attach_match_filename): Uses new __STP_ATTACHED_TASK_EVENTS macro to determine which events to set on a newly found process based on whether the stap_task_finder_target structure has a vm_callback defined. (stap_start_task_finder): Ditto.

|
* Reduce the number of actionremaining checks.Josh Stone2008-06-132-43/+45
| | | | | The generated code now only checks the actionremaining count at control points and after executing a large sequence of statements.
* Minimize last_error checking.Josh Stone2008-06-132-83/+57
| | | | | | The old behavior was to check last_error all over the place, and if set, jump to the out-label. Now it's changed to just jump to the out-label directly after setting last_error.
* Tweak the configure script to play nice with Debian libs.Josh Stone2008-06-132-9/+201
| | | | | | | ./configure now accepts --enable-staticdw, which alters the link settings so they work with static libdw. Tested on Ubuntu Hardy.
