| * utrace/ia64: Fix syscall_get_set_args_cb() to handle syscalls via syscall()Masami Hiramatsu2009-04-221-3/+10
| | | | | | | | | | | | * runtime/syscall.h (syscall_get_set_args_cb): Fix to decode user stack collectly in case of syscall(), and check the maximum number of syscall arguments.

| * Make sdt.h big endian aware.Stan Cox2009-04-222-15/+15
| | | | | | | | | | | | * sdt.h: Use .quad instead of .long for .probe section addresses. ia64 and s390 require 'nop 0' and x86 tolerates it. * tapsets.cxx (build): Fetch probe_name in a big endian friendly fashion.
| * Correct sigmon.meta example title and name.Sunzen Wang2009-04-225-6/+6

| | | | | | | | | | | | * translate.cxx (dump_unwindsyms): Just check that dwfl_module_relocations() return more than 1 relocation section bases before calling dwfl_module_address_section().
| * [tracepoints] Resolve implicit trace_X useJosh Stone2009-04-211-1/+2
| | | | | | | | | | | | | | Some of the tracepoints are actually being called in inlines in the common headers (e.g. trace_kmalloc), which is causing errors about implicit function declarations. We don't care about ever running the code in the tracequery module, so I'm just suppressing that error.
| * [tracepoints] Don't use TRACE_HEADER_MULTI_READJosh Stone2009-04-211-4/+0
| | | | | | | | | | | | | | At one point that macro was needed to get all of the tracepoints on the tip tree, but now it's causing us to get duplicate stapprobe_X definitions. AFAICS, we're now getting all tracepoints even without MULTI_READ, so I'm pulling that workaround out.
| * Use tokenize() for splitting @cast's module listJosh Stone2009-04-211-7/+6

| |
| * Refine the @cast-with-header syntaxJosh Stone2009-04-215-25/+45
| | | | | | | | | | | | | | The special syntax to generate a module for type information is now: - "kernel<path/to/header.h>" to use the kernel's build environment - "<path/to/header.h>" to use no special build environment, and so use gcc's default parameters only (for user mode).
| * Set MAXSTRINGLEN to 133 for uprobes_ustack.exp test on 64 bit.Mark Wielaard2009-04-211-1/+4
| | | | | | | | | | | | | | | | Needs extra space since on 64bit the last ubacktrace string is 7 entries * (16 hex + 2 for 0x + 1 space) = 133 chars. Default MAXSTRINGLEN is 128 chars. * testsuite/systemtap.base/uprobes_ustack.exp: Add -DMAXSTRINGLEN.
