* Fix uninitialized line numbers in the function specJosh Stone2009-09-181-1/+4
| | | | | | | | | The rewrite of parse_function_spec left the line numbers uninitialized when not used, but elsewhere was depending on that. Fix the uninit, and also don't depend on it. * tapsets.cxx (dwarf_query::parse_function_spec): Init line stuff. (query_cu): Branch on the spec_type, not the line contents.
* PR10655 part 1: uprobes: track sdt semaphores properlyFrank Ch. Eigler2009-09-183-37/+52
| | | | | | | | | | | | | | | | | | | commit 6846cfc8 introduced an unintended side-effect where semaphore tracking was identified with stap_uprobe_specs[] elements, which are normally static/const. This kernel patch <http://article.gmane.org/gmane.linux.kernel/854187> catches and panics on this. The cure is to move the variable over to the stap_uprobes[] array. * tapsets.cxx (uprobe emit_module_decls): Add sdt_sem_address to stap_uprobe{} struct, to contain per-process relocated semaphore address. (emit_module_decls,_init): Remove tsk field, restore constness of appropriate locals. Activate uprobe semaphore right around uprobe activation time. Remove semaphore clearing upon process exit, since by then it's gone. (emit_module_exit): Use remembered relocated semaphore address to clean up. Fix "-uprobe" DEBUG_UPROBES message. * runtime.h: #include <linux/sched.h>. * dtrace.in (*_semaphore): Make it an unsigned short - intended 16 bits on all common architectures/multilibs.

| | | | | | | | | | | | | | | | | | Allocated section needs to be writable when creating pic shared objects because we store relocatable addresses in them. We used to make this read only for non-pic executables, but the new semaphore support relies on having a writable .probes section to put the enabled variables in. * includes/sys/sdt.h (ALLOCSEC): Define unconditionally as "aw".

| | | | | | | | | | It's important for macros like this to appear as a single statement, so they won't break the control flow of the caller. The new STAP_SEMAPHORE macro was breaking this masquerade, but now I've moved it inside of the do-while block. * includes/sys/sdt.h (STAP_SEMAPHORE): Define the disabled case empty. (STAP_PROBE[1-10]_): Move the semaphore inside the do-while block.
