* PR5930: Address-op for $target and @cast membersJosh Stone2009-07-1515-2/+100
| | | | | | | | | | | | | | | | This allows the '&' operator to get the address of @cast and $target variable expressions. * staptree.h (target_symbol): add addressof field * staptree.cxx (target_symbol::print): print '&' for addressof (cast_op::print): ditto * parse.cxx (parser::parse_value): allow '&' prefix on $target/@cast * dwflpp.cxx (dwflpp::translate_final_fetch_or_store): allow taking the computed address without actually doing a final fetch. * tapset* (*::visit_target_symbol): throw errors for $vars w/o addresses * testsuite/systemtap.base/cast.stp: add &@cast test * testsuite/semok/target_addr.stp: test '&' on different member types * testsuite/semko/target_addr?.stp: test failure on bitfields/registers

* Don't accidentially use user space ntohs function.Mark Wielaard2009-07-111-2/+5
| | | | | | | | | The definition of ntohs comes from user space include headers netinet/in.h which could define it as function instead of macro. So use builtin kernel be16_to_cpu instead. * tapset/aux_syscalls.stp (_struct_sockaddr_u): Define and use _stp_ntohs as be16_to_cpu.

| | | | | | | | | | | | | | | | Allocated section needs to be writable when creating pic shared objects because we store relocatable addresses in them. * includes/sys/sdt.h (ALLOCSEC): New macro, depends on __PIC__. (STAP_PROBE_DATA_): Use new ALLOCSEC macro.
| * Remove the filename copy from token->locationJosh Stone2009-07-094-37/+30
| | | | | | | | | | The location already has a pointer to a stapfile with the filename, so there's no need to keep an extra copy.
| * Optimize string usage in the lexerJosh Stone2009-07-092-113/+101
| | | | | | | | | | This speeds up the parsing stage >2x, mostly by minimizing string construction and comparison where char comparison will do.

| | | | | | | | | | | | | | | | | | | | | This will first read in the symbol table for modules, and update the dwarf cu_function_cache with aliased names too. Then when iterating in dwarf, all of the possible names are matched, instead of only the canonical dwarf name. * dwflpp.cxx (dwflpp::iterate_over_functions): call update_symtab, and track wildcard addresses in a set to avoid alias dupes * dwflpp.h (symbol_table::Compare): removed * tapsets.cxx (symbol_table::map_by_addr): replaces list_by_addr (symbol_table::sort): removed -- multimap doesn't need sorting (symbol_table::mark_dwarf_redundancies): removed, see update_symtab (symbol_table::purge_syscall_stubs): remove map elements inline (dwarf_query::handle_query_module): preload the symtable.

* PR10335 systemtap.base/strftime.exp hangs.Mark Wielaard2009-06-261-20/+3
| | | | | | | | This only happened if there was a lot of cruft in the testsuite dir since expect wasn't "draining" the output of the spawned ls command for some reason. Work around it by just using tcl file globs to match. * testsuite/systemtap.base/strftime.exp: Test with glob and file exists.
* PR10323 Some ustack exelib.exp tests fail with prelinked shared libs.Mark Wielaard2009-06-252-6/+8
| | | | | | | | | | | | For shared libraries (.dynamic sections) we need the eh frame section address offset. This is the sh_addr if the shared library isn't prelinked (since the base load address is zero in that case), otherwise it is the module start address minus the bias (which also works for the non-prelinked case). * translate.cxx (get_unwind_data): Adjust eh_addr for module start and bias if module isn't absolute (has no relocations). * testsuite/systemtap.exelib/ustack.tcl: Accept all prelink tests.
