* stap autoconf test for kernel stack trace supportTim Moore2009-03-041-4/+3
| | | | | | | | | | * buildrun.cxx (compile_pass): Add autoconf line for stack trace test, which defines STAPCONF_KERNEL_STACKTRACE. * runtime/autoconf-save-stack-trace.c: New file. * runtime/stack.c : Use STAPCONF_KERNEL_STACKTRACE instead of tests for kernel configuration and versions. * runtime/stack-i386.c : ditto * runtime/stack-x86_64.c : ditto
* PR9866 band-aid: deactivate new CONFIG_STACKTRACE code for older kernelsFrank Ch. Eigler2009-02-181-3/+4

* Fixed stack.c compile problems on systems with older kernels (like RHEL4).David Smith2009-02-131-0/+2
| | | | | | | 2009-02-13 David Smith <dsmith@redhat.com> * stack.c: Fixed compile problems on systems with older kernels (like RHEL4).
* Use kernel stack backtrace support when availableTim Moore2009-02-111-0/+87
| | | | | Define new functions that use the kernel support to do a backtrace of other tasks than current.
* Use 'static' as much as possibleJosh Stone2009-01-281-3/+3
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
