* dtrace: Output probe calling sequence comment
|
|
|

|
|
|
|

* tapsets.cxx (dwflpp::iterate_over_labels): Renamed from
iterate_over_cu_labels, method signature simplified.
(query_srcfile_label): New.
(query_cu): Use above.

|
|
|

* tapsets.cxx (dwflpp::translate_components): Eliminate the extra
die-dereference at the end of the loop (a regression from @casts).
* runtime/loc2c-runtime.h (store_bitfield): Use the target as the
representative type, since the base is always int64_t. Also be a
bit more aggressive with masking and parentheses.
* testsuite/systemtap.base/bitfield.*: New test for R/W bitfields.
|
|
|
|
|
|
| |
* tapsets.cxx (iterate_over_cu_labels): Treat -l specially so the
output of a .label can be improved.
* labels.stp: Test -l

There was nothing wrong with the probe itself, but because the body
was empty the compiler optimised away the actual call...
* testsuite/systemtap.base/uprobes_lib.exp: Activate main exe probe, expect
more output.
* testsuite/systemtap.base/uprobes_lib.stp: Also probe main and main_lib.
* testsuite/systemtap.base/uprobes_exe.c: Put some code in main_func.
* testsuite/systemtap.base/uprobes_lib.c: Likewise for lib_func.
|
|
|
|
|
|
| |
* tapsets.cxx(dwflpp::iterate_over_cu_labels): New parameter function.
Do wildcard match for function.
* testsuite/systemtap.base/labels.exp: Test .label function handling.
|
|
|
|
| |
* tapsets.cxx (dwflpp::iterate_over_cu_labels): Compare with strcmp not strncmp.
|
|
|
|
| |
* testsuite/systemtap.base/stmt_rel.exp: Rewrite.
|
| |
|
| |
|
|
|
|
|
|

* testsuite/lib/systemtap.exp: Define here.

utrace_support_present logic.

As it was, the ATTENTION was causing expect mismatches even when the
test worked fine. The warning is served just as well from the expect
script before starting the test.

Earlier today, I posted a runtime patch for the insn.block probe point.
Once that patch is committed, the insn.block probe can be safely tested
on any architecture. The attached patch adds such a testcase to the
testsuite.

This checks that kernel.trace("*") will compile, with all context
variables accessed as well. For kernels without tracepoints, it will
just hit a "begin" and quit.
This doesn't ensure that kernel.trace("*") will always find something
when it should, though...

Replaced cpp VA_ARGS in sdt.h with explicit enumeration of arguments

cflags variants to the sdt.exp test case.

module_start for shared objects so don't call module_address_to_global for the
statement address.

shared object .label("L") and so .statement(N).

This test simply checks that _gettimeofday_init and _gettimeofday_kill
are pulled in when gettimeofday is used, and also that they are NOT
pulled in when gettimeofday is not used.
