* Unlocks global variables, then calls _stp_print_flush().David Smith2009-08-171-4/+4

* 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.
* PR10228: use task_finder_vma for -d /user/object files.Frank Ch. Eigler2009-08-149-115/+46

(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".

* 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.

* | PR10499: Integrate attributes in dwarf_decl_file/lineJosh Stone2009-08-103-6/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To fixup REG_IP to show the correct value after a [ku]probe trap we assigned the address of the actual instruction pointer of the probed instruction. That doesn't work on architectures, s390 and ia64, where REG_IP is not a simple lvalue. Just don't try to fixup the address in those cases. If this isn't enough, the uprobe_stmt_num.exp testcase will point this out. * runtime/regs.h: Define REG_IP_LVALUE for x86_64, i386, powerpc64 and arm. * tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Only fixup REG_IP when REG_IP_LVALUE is defined.

| * Remove as_root calls from the printf testsuiteJosh Stone2009-08-055-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | Once upon a time, we would use sudo staprun, and so output files from "-o" were owned by root. For a while now we've used a setuid staprun instead, and the output files are created by stapio as the user. Thus, we don't need as_root to remove those files anymore. * testsuite/systemtap.printf/end1b.exp: Clean up without as_root. * testsuite/systemtap.printf/mixed_outb.exp: Ditto. * testsuite/systemtap.printf/out1b.exp: Ditto. * testsuite/systemtap.printf/out2b.exp: Ditto. * testsuite/systemtap.printf/out3b.exp: Ditto.
| * Don't spawn uprobes tests with sudoJosh Stone2009-08-055-14/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using spawn with sudo doesn't work well, because the password prompt won't go to the correct TTY. The only reason that the uprobes tests needed to do this is so uprobes.ko could be built as root. Now instead, I've added a pre-check that will directly call the uprobes make with sudo (via the as_root proc). * testsuite/lib/systemtap.exp (uprobes_p): Check and build uprobes.ko. * testsuite/systemtap.base/uprobes.exp: Use uprobes_p; don't spawn sudo. * testsuite/systemtap.base/bz6850.exp: Ditto. * testsuite/systemtap.base/bz10078.exp: Ditto. * testsuite/systemtap.base/bz6905.exp: sudo isn't needed for -p2.
