* PR10746: update test cases related to probe process.*Wenji Huang2009-10-141-1/+1

* bz10475.exp: Use filp_open which has a constant const char argument for test.Mark Wielaard2009-09-071-4/+3
| | | | | | | | | For some reason the do_filp_open const char *pathname argument has changed its name between different kernel versions. Luckily filp_open has a cont char *filename argument that is constant between versions (the test needs a const char* argument to do an array operation on). * testsuite/semok/bz10475.stp: Use filp_open instead of do_filp_open.
* PR10495: allow multiple probe aliases with same nameFrank Ch. Eigler2009-08-181-0/+9
| | | | | | | | * elaborate.cxx (match_node::bind): Change ->end to ->ends[] vector. (find_and_build,build_no_more): Iterate over ends[]. * elaborate.h: Corresponding changes. * testsuite/semok/thirtyfour.stp: New test. * NEWS, doc/langref.tex: Note this.

* PR5930: Address-op for $target and @cast membersJosh Stone2009-07-151-0/+11
| | | | | | | | | | | | | | | | 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

* Allow @cast failures to get optimized awayJosh Stone2009-05-081-0/+6
| | | | | | We have the saved_conversion_error field, but I wasn't using it. Now @cast errors are saved in that field, so they're only seen if the optimizer doesn't remove the @cast.
* Refactor anonymous lookups in translate_componentsJosh Stone2009-05-081-1/+5
| | | | | | | | | | | | | | | | | | | The previous code recursed the entirety of translate_components, and it seemed to be restarting the components list every time, so it would only work if the anonymous portion was the first component. Even then, examining the code output by semok/thirtythree revealed that it wasn't fully translating the locations when multiple anonymous pieces were involved. Instead, it now recurses in a separate function, find_struct_member, which does just enough to find the member die and return. It also builds a vector of the locations passed through, so translate_components can output code for the full chain of anonymity. The generated code for semok/thirtythree's $page->mapping now appears to match the offsets from my manual inspection of struct page. I also added a test for $page->first_page->mapping, which works now but would segfault the old code.
* PR10007: Avoid probing syscall entry points in the testsuite.Ananth N Mavinakayanahalli2009-04-302-2/+2
| | | | While there, fix minor issues with the s390x syscall tapset.
* Refine the @cast-with-header syntaxJosh Stone2009-04-211-2/+2
| | | | | | | The special syntax to generate a module for type information is now: - "kernel<path/to/header.h>" to use the kernel's build environment - "<path/to/header.h>" to use no special build environment, and so use gcc's default parameters only (for user mode).
