| * PR10285. User space PROBE marks aren't found with separate debuginfo.Mark Wielaard2009-06-152-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | The original logic was a little confused. It could end up searching the separate debuginfo twice instead of falling back to the main elf file. Now we explicitly search the main elf file first (where the .probes section really should be) and only then fall back to the separate debuginfo file. * tapsets.cxx (dwarf_builder::probe_table::probe_table): Search main elf file first, then fall back on separate debuginfo file if necessary. * testsuite/systemtap.exelib/exelib.exp: Enable mark.tcl testcase. main elf file or the debuginfo file, but would interpret

| * PR10274 Fix exelib -O3 testcase.Mark Wielaard2009-06-153-10/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The testcase now uses noinline, an empty asm statement and a volatile variable to prevent the function getting inlined, being totally unrolled or the recursive call being replaced with an inner-iteration. This does defeat part of the testcase though, which was testing unwinding through an optimized recursive function. But it seems the best we can do. * testsuite/systemtap.exelib/exelib.exp: Add -O3 to the mix. * testsuite/systemtap.exelib/uprobes_exe.c: Use volatile bar and mark main_func noinline. * testsuite/systemtap.exelib/uprobes_lib.c: Use volatile foo and mark lib_func noinline.

| * | PR10260: Clean up all resources after init errorsJosh Stone2009-06-101-0/+8
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | When anything in systemtap_module_init fails, and we return non-zero, then the module load is aborted. The normal module unload path (systemtap_module_exit) is not even attempted, so we need to make sure that all partially-allocated resources are returned. Our timer callbacks for the gettimeofday subsystem are a classic example of this error. If we don't unregister the timers before aborting init, they will later be called and cause a kernel fault. We also were neglecting to free the percpu context. A memory leak is less harmful, but that's fixed now too.
| * Fix condition propagation across aliasesJosh Stone2009-06-093-5/+40
| | | | | | | | | | | | | | | | | | | | When an instance of an alias has a condition, that condition gets propagated to each of the locations that the alias defines. However, the copy of the location list was not a deep copy, and so all other instances of the alias would also incorrectly receive the condition. This patch makes the location list copy a little deeper, and adds a test case which demonstrates the issue.

| * Remove the spurious sdt @cast expansionJosh Stone2009-06-091-3/+0
| | | | | | | | | | | | | | The result of sdt's private @cast expansion was not being used, and it's not really needed anyway. The global cast visitor is registered to run as a post-processing step on ALL functions and probes, and so it will pick up and expand sdt's casts too.

| | | | | | | | | | | | | | | | | | (redo commit 3d022fa9c6bdbca383dfc639d08d65287c708f56) * tapsets.cxx (dwarf_builder::probe_table::probe_table): gcc 4.4 complains that shdr may be used uninitialized. I added returns to ensure that it's ok, but gcc still complains. Set the thing to NULL as well to silence the beast.
| * * tapsets.cxx (probe_table): Make mark_name and sess refs.Stan Cox2009-06-081-115/+115

| * Remove dwflpp::default_nameJosh Stone2009-06-082-17/+4
| | | | | | | | | | | | It was just a basic NULL check, but creating its string temporaries was causing a fair slowdown. Removing this function and adjusting the callers shaves ~5% off the syscall.* elaboration time.
| * Let query_module abort early for simple matchesJosh Stone2009-06-082-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | query_module was already returning DW_CB_ABORT when a simple match was found, but dwflpp::iterate_over_modules was ignoring that and instead forcing the module loop to restart. The only way out of the loop was with the pending_interrupts flag, which is only for signalled interrupts. Now iterate_over_modules will only attempt the dwfl_getmodules loop once, since that loop will only abort if the CB returns DW_CB_ABORT. Then query_module is also modified to return ABORT if pending_interrupts is flagged. My trusty test, stap -l syscall.*, is nearly 2x faster with this change. Empirically, I found that the kernel object is always the first "module" returned, so the syscall probepoints always gets to short-circuit the loop right away.
