| * PR10538: Improve location lookup for unionsJosh Stone2009-08-191-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | We had a bug that the starting call to find_struct_member used the same memory for the parentdie and the resulting member. If parentdie is a union, then the first member probably won't have a location, and we actually assert that it must be a union. Since we wrote the result in the same memory, we lost the real info about the parent, and so the assertion failed. * dwflpp.cxx (dwflpp::translate_components): Use distinct memory for the parent and resulting member in the call to find_struct_member. (dwflpp::find_struct_member): Remove the needless parentdie copy.

| | | | | | | | | | Partial testcase for PR10533 (inlined vars) and 10537 (inlined labels) currently we cannot use the full testcase since stap doesn't support probing multiple instances of inlined labels. * testsuite/systemtap.base/inlinedvars.exp: New file. * testsuite/systemtap.base/inlinedvars.stp: Likewise. * testsuite/systemtap.base/inlinedvars.c: Likewise.
* PR10533 inlined vars are not always found (dwflpp).Mark Wielaard2009-08-181-14/+26
| | | | | | | | | | | | | | dwflpp::find_variable_and_frame_base switched too early to "pyshical view" of die tree. We need to lookup the var in the "syntactical view" of the die tree first. Then when we see a DW_TAG_inlined_subroutine while walking the syntactical die tree as returned by dwarf_getscopes for a given variable to retrieve the frame base, then we need to switch to walking the physical die tree where the subroutine is inlined. * dwflpp.cxx (find_variable_and_frame_base): Don't immediately go to die_scopes, but lookup var first based on pc. Then switch "die branches" when searching for frame base and a DW_TAG_inlined_subroutine is encountered.
* PR10533 inlined vars are not always found (lo2c-test off-by-one).Mark Wielaard2009-08-181-1/+1
| | | | | * loc2c-test.c (handle_variable): Set inner to zero after calling dwarf_getscopes_die(), for loop will increase inner.

| | | | | | | * tapsets.cxx (tracepoint_derived_probe_group::emit_module_decls): Use probe_locals to set the tracepoint arguments for the probe. * testsuite/systemtap.base/tracepoints.exp: Include the arguments in the pass-4 tracepoint test.

* Unlocks global variables, then calls _stp_print_flush().David Smith2009-08-171-4/+4
| | | | | * translate.cxx (c_unparser::emit_probe): Unlocks global variables, then calls _stp_print_flush() (instead of the other way around).
* Cache failed tracepoint headers tooJosh Stone2009-08-141-2/+8
| | | | | | | | | | Rather than re-attempting a tracepoint header that fails to compile, we now save an empty file into the cache to indicate "nothing to see here." See also PR10424. * tapsets.cxx (tracepoint_builder::get_tracequery_module): Use /dev/null as the empty result file if make_tracequery fails. (tracepoint_builder::init_dw): Ignore empty tracequery modules.

(dump_unwindsyms): Associate vmcbs with user-space unwindsyms entries.
* usability: don't suppress pass-4 compiler errorsFrank Ch. Eigler2009-08-141-1/+1
| | | | | | ... since a pass-4 compilation error is just as bad as pass-2 error. * buildrun.cxx (run_make_cmd): Remove "2>&1".

| | | | | | * tapsets.cxx (uprobes::emit_module_decls): Compute MAXUPROBES with x-treme kl3v3rn3ss. * stap.1.in: Clarify MAXUPROBES.
* PR10461: Probe identical functions only onceJosh Stone2009-08-112-10/+14
| | | | | | | | | | | | | | | In C++ especially, a function definition in a header may be compiled into multiple CUs, but the linker will merge those into a single output function. We don't want to place multiple probes on the same function. The dupe-detection from the alias code (commit 1c6b77e5) already tracks identical functions within a CU, so I've just lifted this to instead track function entrypcs at the module level. * dwflpp.cxx (dwflpp::iterate_over_functions): Remove dupe checks. * tapsets.cxx (dwarf_query): Add alias_dupes set to the query. (dwarf_query::handle_query_module): Reset the dupes for each module. (query_dwarf_func): Check that we only probe each entrypc once.
* Don't call dwarf_lowpc after dwarf_entrypc failsJosh Stone2009-08-111-7/+0
| | | | | | | | The implementation of dwarf_entrypc already checks for _lowpc, so it's redundant for us to attempt a _lowpc call too. * dwflpp.cxx (dwflpp::function_entrypc): Remove XXX comment. (dwflpp::die_entrypc): Don't bother with _lowpc if _entrypc fails
* Improved context.exp error handling.David Smith2009-08-113-10/+8
| | | | | | | | | | * testsuite/systemtap.context/context.exp: Makes sure errors are output to the log file. Also, a Makefile is copied with 'cp -p' to avoid make erroring out if the Makefile's date is in the future (as can be the case if running the test over nfs). * testsuite/systemtap.context/args.tcl: Makes sure 'close' errors are ignored. * testsuite/systemtap.context/backtrace.tcl: Ditto.

| | | | | | | | | | | | | | | | | | | | | | | | | | Elfutils prior to 0.143 didn't use attr_integrate when looking up the decl_file or decl_line, so the attributes would sometimes be missed. For those old versions, we define custom implementations to do the integration. * dwarf_wrappers.cxx (dwarf_decl_file_integrate): New. (dwarf_decl_line_integrate): New. * dwarf_wrappers.h: Add macros to redirect calls to the above functions. * dwflpp.cxx (dwflpp::iterate_over_labels): Replace a manual attribute lookup that is the same as dwarf_decl_line.
* | Simplify _ELFUTILS_PREREQ checkingJosh Stone2009-08-105-30/+26
| | | | | | | | | | | | | | We were jumping through a few hoops to deal with elfutils < 0.138 that did not have the _ELFUTILS_PREREQ macro. I've added an always-false dummy macro to take its place when it doesn't exit. All of the other "#ifdef _ELFUTILS_PREREQ" ugliness can now go away.
* | Zap dwarf_diename_integrateJosh Stone2009-08-075-41/+20
|/ | | | | | The dwarf_diename in elfutils learned a long time ago to use dwarf_attr_integrate when looking up the name. Our minimum elfutils 0.126 has this, so we don't need to kludge it ourselves.
