* An i386 kprobe needs regparm(0) to access args.Stan Cox2009-06-261-0/+17

* 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.
* stap-* scripts should be executable.Dave Brolley2009-06-254-0/+0

* Only compile with plain gcc for exelib.exp testcases.Mark Wielaard2009-06-251-1/+4
| | | | | | | g++ is also supported but disabled because it didn't add much interesting differences in binaries and exploded the test search case a bit. * testsuite/systemtap.exelib/exelib.exp: Disable g++ by default, but keep support for enabling it.
* Add seperate debuginfo after prelinking to exelib.exp tests.Mark Wielaard2009-06-251-2/+16
| | | | | | | | | | | | We split debuginfo before prelinking, that means that the base load address of the .so is non-zero, while for the .debug files they are zero. In the other case we supported sep-debug without prelinking both .so and .debug load bases were zero. In this new test case both base load addresses are non-zero. * testsuite/systemtap.exelib/exelib.exp: Add libdebug == "sep-after" to indicate separate debuginfo after prelinking library. Skip sep-after if not prelinking.

| * Enable exelib.exp prelink tests except for ustack.tcl.Mark Wielaard2009-06-242-2/+5
| | | | | | | | | | * testsuite/systemtap.exelib/exelib.exp: Enable prelink "yes". * testsuite/systemtap.exelib/ustack.tcl: Ignore any prelink test (PR10323).
| * PR10305 Mark probes fail on prelinked shared library.Mark Wielaard2009-06-243-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Mark probes rely on literal statement addresses, these are based on the on-disk module address space. Introduce helper function to turn such addresses into symbol addresses as expected by libdwfl. Also properly adjust for dw bias when such addresses are used in dw queries. * dwflpp.h (dwflpp::literal_addr_to_sym_addr): New method. * dwflpp.cxx (query_cu_containing_address): Don't "globalize" address. (literal_addr_to_sym_addr): New method. * tapsets.cxx (query_module_dwarf): Turn literal addresses into symbol addresses. (query_dwarf_func): Likewise and adjust for dw module bias.

| * Remove needless string copyingJosh Stone2009-06-232-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | More fat-trimming optimization for ~7% off listing syscall.*. * dwflpp.cxx (dwflpp::iterate_over_functions): remove a parameter copy (dwflpp::module_name_matches): Use const string& parameters (dwflpp::name_has_wildcard): Ditto. (dwflpp::module_name_final_match): Ditto. (dwflpp::function_name_matches_pattern): Ditto. (dwflpp::function_name_matches): Ditto. (dwflpp::function_name_final_match): Ditto.

* PR 10313 Build error due to deprecation of elf_getshstrndx in elfutils (old)Mark Wielaard2009-06-231-0/+3
| | | | | | | | Really old versions of elfutils didn't have version.h, but we still want to support them. So add workaround also for that case. * dwflpp.h: Define elf_getshdrstrndx as elf_getshstrndx also for really old elfutils versions.
* PR 10313 Build error due to deprecation of elf_getshstrndx in elfutils.Mark Wielaard2009-06-233-4/+11

* Testcase For str_replace()Varun Chandramohan2009-06-222-0/+39
| | | | | | | | | | | | This patch adds the test case needed for this function. I have added few tests. If required more can be added in future. As discussed in previous version, the testcase patch has been reverted to the original as the str_replace() functionality has changed wrt to error handle.

* Add str_replace() To TapsetsVarun Chandramohan2009-06-221-0/+33
| | | | | | | | | | | | | | | | | | This patch adds a search and replace string functionality to existing tapsets. The functionality is as follows: The function takes in a parent string and searches for a substring as specified by the user. If substring not found, the parent string is returned. If substring is found, it is replaced by another string and returned. NOTE: The function will search and replace all the occurrence of substrings in a parent string when matched.
