| | | | | | | 2008-06-27 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_derived_probe_group::emit_module_decls): Fix bug in handling process(PID) probes.
* Added tests for 'process(PID)' variants.David Smith2008-06-272-6/+67
| | | | | | | 2008-06-27 David Smith <dsmith@redhat.com> * systemtap.base/utrace_p4.exp: Added tests for 'process(PID)' variants.
* This commit makes changes to the VFS tapset. The changes include deprecation ofroot2008-06-273-6/+768
| | | | | | | some old probe points to older versions of kernel, adding new helper C functions and probe points for the VFS subsystem. A new testcase is created for the VFS tapset which performs a compile test (i.e. up4) on the probe points to verify sanity. These details can also be found in the ChangeLog.

* Get rid of the dynamic_cast<>s in void_statement_reducer.Josh Stone2008-06-191-57/+49
| | | | | | | | Instead, visit_expr_statement can explicitly load a pointer to use for back-references. I also decided to be less-clever about reusing expr_statements. It's a little leakier as a result, but I like having less magic in the air.

| | | | | | | | | | | | | | | | 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.

| | | | | | 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
