commit 08d1d520616557f6ff7dd023e260ad6577e9e0e8
Author: Mark Wielaard <mjw@redhat.com>
Date: Mon Jan 18 09:13:30 2010 +0100
PR11173 Markers get a bad address in prelinked libraries.
Our literal_addr_to_sym_addr() function was just wrong. To compensate for
raw addresses read from elf (either given by the user or through a mark
transformation) we need to know what the elf_bias is (as returned by
dwfl_module_getelf) before feeding them to any libdwfl functions.
* tapsets.cxx (query_module_dwarf): Always add elf_bias to raw function or
statement addresses before calling query_addr().
(query_addr): Don't call literal_addr_to_sym_addr().
* dwflpp.h (literal_addr_to_sym_addr): Removed.
* dwflpp.cxx (literal_addr_to_sym_addr): Likewise.

Make sure cfa_ops are always retrieved through dwfl global address.
dwflpp::translate_location() works on the dw address space, but
get_cfa_ops() starts out with dwfl calls (only dwarf_cfi_addrframe()
needs to be adjusted for bias).
* dwflpp.cxx (translate_location): Pass pc plus module bias through to
get_cfa_ops.
(get_cfa_ops): Adjust for bias when calling dwarf_cfi_addrframe(),
add frame start/end address when found if verbose logging.
* testsuite/systemtap.exelib/lib.stp: Add $foo and $bar variables to
process.function probes.

commit a2d399c87a642190f08ede63dc6fc434a5a8363a
Author: Josh Stone <jistone@redhat.com>
Date: Thu Feb 4 17:47:31 2010 -0800
PR11234: Rewrite __get_argv without embedded-C
We now implement __get_argv's string building in pure stap script.
Also, every argument is now quoted, which is different than before, but
it's much more robust about handling special characters.
