On 64-bit, each item is 24 bytes, so with 14 entries that's 336 bytes. That doesn't need to be on the stack -- static const it is. commit 3620fb20885d0beab00641d8c3522e5960d0805b Author: Josh Stone <jistone@redhat.com> Date: Fri Nov 5 12:36:14 2010 -0700 Add make targets "uprobes" and "install-uprobes" This builds uprobes.ko in $srcdir and $DESTDIR, respectively, because I'm too lazy to type it out all the time. commit 01a2eba861db8433b2937662193bc876ecd5db5f Author: Josh Stone <jistone@redhat.com> Date: Fri Nov 5 12:16:22 2010 -0700 PR10821: Remove large stack variables from the unwinder We tend to use the percpu CONTEXT as a pre-allocated stack, so add the large unwinder variable there too. * runtime/unwind.c (unwind, unwind_frame): Use an unwind_context parameter for the larger data needed. * runtime/stack-$arch.c (__stp_stack_print): Add the unwind_context parameter, and use it for the x86 versions with a dwarf unwinder. * runtime/stack.c (_stp_stack_print, _stp_stack_sprint): Add the unwind_context parameter and pass it along. * translate.cxx (c_unparser::emit_common_header): Add unwind_context the the global CONTEXT when we NEED_UNWIND_DATA. * tapset/context-unwind.stp (*backtrace): Use CONTEXT->uwcontext. * tapset/ucontext-unwind.stp (*backtrace): Use CONTEXT->uwcontext. * buildrun.cxx (compile_pass): Tighten the frame warning to 256 bytes. ----------------------------------------------------------------------- Summary of changes: Makefile.am | 6 ++ Makefile.in | 16 +++- buildrun.cxx | 7 +- runtime/stack-arm.c | 3 +- runtime/stack-i386.c | 27 +++--- runtime/stack-ia64.c | 3 +- runtime/stack-ppc.c | 3 +- runtime/stack-s390.c | 1 + runtime/stack-x86_64.c | 28 +++--- runtime/stack.c | 12 ++- runtime/unwind.c | 102 +++++++++++++---------- runtime/unwind/i386.h | 2 +- runtime/unwind/x86_64.h | 3 +- tapset/context-unwind.stp | 10 ++- tapset/ucontext-unwind.stp | 8 +- testsuite/systemtap.examples/process/pfiles.stp | 4 +- translate.cxx | 3 + 17 files changed, 138 insertions(+), 100 deletions(-) hooks/post-receive -- systemtap: system-wide probe/trace tool
