* Always include libdw using link groups.Josh Stone2008-06-272-278/+7
| | | | | | This is necessary for distros that ship static libdw, Roland suggested that it shouldn't hurt to do it this way on other distros too. It's nicer now not to require the extra "--enable-staticdw" configure flag.
* Fix bug in handling process(PID) probes.David Smith2008-06-272-1/+6
| | | | | | | 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.

* 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.

* 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.
