набор инструментов для отладки и профилирования программ (a suite of tools for debugging and profiling programs)
LACKEY OPTIONS
--basic-counts=<no|yes> [default: yes]
When enabled, Lackey prints the following statistics and
information about the execution of the client program:
1. The number of calls to the function specified by the
--fnname option (the default is main). If the program has
had its symbols stripped, the count will always be zero.
2. The number of conditional branches encountered and the
number and proportion of those taken.
3. The number of superblocks entered and completed by the
program. Note that due to optimisations done by the JIT,
this is not at all an accurate value.
4. The number of guest (x86, amd64, ppc, etc.) instructions
and IR statements executed. IR is Valgrind's RISC-like
intermediate representation via which all instrumentation
is done.
5. Ratios between some of these counts.
6. The exit code of the client program.
--detailed-counts=<no|yes> [default: no]
When enabled, Lackey prints a table containing counts of
loads, stores and ALU operations, differentiated by their IR
types. The IR types are identified by their IR name ("I1",
"I8", ... "I128", "F32", "F64", and "V128").
--trace-mem=<no|yes> [default: no]
When enabled, Lackey prints the size and address of almost
every memory access made by the program. See the comments at
the top of the file lackey/lk_main.c for details about the
output format, how it works, and inaccuracies in the address
trace. Note that this option produces immense amounts of
output.
--trace-superblocks=<no|yes> [default: no]
When enabled, Lackey prints out the address of every
superblock (a single entry, multiple exit, linear chunk of
code) executed by the program. This is primarily of interest
to Valgrind developers. See the comments at the top of the
file lackey/lk_main.c for details about the output format.
Note that this option produces large amounts of output.
--fnname=<name> [default: main]
Changes the function for which calls are counted when
--basic-counts=yes is specified.
