| | | | | | * lket/b2a/Makefile.in: Regenerated. This needed to be done since lket/b2a/README was removed but lket/b2a/Makefile.in still had a reference to it which was causing "make distdir" to fail.

| | | | | * systemtap.samples/pfaults.stp: Since PR 1132 has been fixed, updated to use "$return".

| | | | | | | | | | | PR 3079 * loc2c-runtime.h (deref, store_deref): Fork x86 and x86-64 variants. Remove dysfunctional 64-bit ops from x86. 2006-12-18 Frank Ch. Eigler <fche@elastic.org> * vfs.stp (ppos_pos): Protect contents with deref(), though this blocks operation on i686 due to bug #3079.

| | | | | | | | | * tapsets.cxx (struct dwarf_var_expanding_copy_visitor): Added 'return_ts_map' member variable. (dwarf_var_expanding_copy_visitor::visit_target_symbol): Optimization. If we've already seen this target variable in this return probe, return the last replacement (instead of creating a new replacement).

| | | | | | | | | | | | | * tapsets.cxx (struct dwarf_var_expanding_copy_visitor): Added 'add_probe' member variable. Initialized it in ctor. (dwarf_var_expanding_copy_visitor::visit_target_symbol): Optimization. Instead of generating one entry probe per target variable accessed in a return probe, now just generates one entry probe for all target variables accessed in a particular return probe. It does this by creating a new probe in the new 'add_probe' member variable. (dwarf_derived_probe::dwarf_derived_probe): If add_probe isn't NULL, make sure it gets derived later.
