Without KPROBES very little works atm. But stack.c file is unconditionally
imported, while these two functions are only used through context-unwind.stp.
This at least lets us do simple sanity checks on "plain" kernels.
* runtime/stack.c (_stp_stack_print, _stp_stack_snprint):
Wrap in #if defined (CONFIG_KPROBES).

* buildrun.cxx (compile_pass): Add autoconf line for stack trace
test, which defines STAPCONF_KERNEL_STACKTRACE.

* runtime/stack.c : Use STAPCONF_KERNEL_STACKTRACE instead of
tests for kernel configuration and versions.
* runtime/stack-i386.c : ditto

* stack.c: Fixed compile problems on systems with older kernels
(like RHEL4).
|
| |
|
|
|
| |
Define new functions that use the kernel support to do a backtrace of other
tasks than current.

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.

Recognize when a kretprobe trampoline was hit and continue with inexact stack dump.
Also some testsuite changes.
