| * Ignore kernel functions with "absolute" addresses.Mark Wielaard2009-02-201-7/+6
| | | | | | | | | | | | | | translate.cxx (dump_unwindsyms): Augment the test for creating the stap-symbols to be STT_FUNC && !(SHN_UNDEF || SHN_ABS). The combination STT_FUNC && SHN_ABS only seems to occur on older i386 kernels and covers the vDSO "functions" we were seeing.

| | * Update guidelines for the ChangeLog-less worldJosh Stone2009-02-192-19/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Getting rid of ChangeLogs doesn't mean that we get a free ticket -- we now need to be more diligent about providing meaningful commit messages. I've updated the HACKING file with a first draft of new guidelines, but we may still revise what we feel is appropriate detail in the logs. I removed the ChangeLog section from the tapset/DEVGIDE entirely, and also fixed the path where examples are stored.
| | * Kill all ChangeLogsJosh Stone2009-02-1915-18856/+76
| | | | | | | | | | | | | | | | | | Mark Wielaard, a dear friend of the departed, will be performing a song and dance at the funeral services to commemorate the joyous times that they had together.
| | * Clean up extraneous build warningsJosh Stone2009-02-192-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The testsuite Makefile doesn't have any useful targets except check and installcheck, and those two are invoked directly by the top-level Makefile. So, I'm removing testsuite from automake's SUBDIRS, but keeping it in DIST_SUBDIRS for cleanup. I also renamed our top-level check target to check-local, so it cooperates with automake's check instead of overriding it.

| * Enable dwarf expansion of @castsJosh Stone2009-02-184-35/+406
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will iterate over the module and its CUs looking for the type definition, and then work with loc2c to dereference the pointer. * loc2c.c (c_translate_argument): Create a dummy location to start the address computation from a function parameter. * translate.cxx (base_query, dwarf_query): Move some members from base_query to dwarf_query, so the former can be more generic. Also add a constructor using a module string instead of probe parameters. (dwflpp::query_modules, dwflpp::iterate_over_modules): Use a generic base_query instead of a dwarf_query. (dwarf_cast_query): New query to scan the modules and CUs for a matching type definition, and then produce a code fragment to deref each component. (dwarf_cast_expanding_visitor): Tries to replace @casts with a function call to the result of a dwarf_cast_query. (dwflpp::declaration_resolve): Search by name instead of by die. (dwflpp::translate_components): Use the incoming vardie as the first type die, so we don't assume that attr_mem has a DW_AT_type already. (dwflpp::literal_stmt_for_pointer): Construct a C fragment that starts with a pointer argument (THIS->pointer) and dereferences each member component from there. (*_derived_probe::register_patterns): Take a session parameter instead of a match_node, so we can manipulate session-wide data. (dwarf_derived_probe::register_patterns): Add a session code filter to expand @casts with a dwarf_cast_expanding_visitor.
| * Enable session-wide code filteringJosh Stone2009-02-183-0/+18
| | | | | | | | | | | | | | | | | | | | This will be used to hook to dwarf_builder to all functions and probes so it can attempt @cast expansion. * session.h (systemtap_session): Add a vector of update_visitors that will act as filters for all probes and functions. * elaborate.cxx (semantic_pass_symbols): Run probes and functions through each registered code filter.
| * Provide dwarf module names as defaults in @cast()sJosh Stone2009-02-182-0/+18
| | | | | | | | | | | | * tapsets.cxx (dwarf_var_expanding_visitor::visit_cast_op): While expanding dwarf probes, provide the current module as a default to @casts without a module name.
| * Add high-level support for @cast()ingJosh Stone2009-02-187-1/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This handles all of the parsing, traversal, and optimization. It doesn't actually resolve the cast yet though. * staptree.h (struct cast_op, visitor::visit_cast_op): New. * staptree.cxx (cast_op::print/visit, various visitor::visit_cast_op's): Incorporate cast_op into the basic tree operations. * parse.cxx (parser::parse_symbol): Parse @cast operator with an expression operand, type string, and optional module string. * translate.cxx (c_unparser::visit_cast_op): Error out if a @cast survives to translation. * elaborate.cxx (typeresolution_info::visit_cast_op): Error out if a @cast survives to type resolution. (symbol_fetcher::visit_cast_op): treat @casts as a symbol target (void_statement_reducer::visit_cast_op): unused @casts can be discarded, but the operand should still be evaluated.
