On perf top, the -s option is used for --sort, but the man page
contains invalid documentation of -s option for --sym-annotate.

perf probe: Clarify x86 register naming for perf probe

2014-03-14T14:20:44+00:00

Clarify how to specify x86 registers in perf probe. I recently ran into
this problem and had to figure it out from the source.

perf mem: Clarify load-latency in documentation

2014-03-14T14:20:44+00:00

Clarify in the documentation that 'perf mem report' reports use-latency,
not load/store-latency on Intel systems.

This often causes confusion with users.

perf record: Rename --initial-delay to --delay

2014-01-14T20:58:12+00:00

To be consistent with the equivalent option in 'stat', also, for the
same reason, use -D as the one letter alias.

perf record: Rename --no-delay to --no-buffering

2014-01-14T20:57:04+00:00

That is how the option summary describes it and so that we can free
--delay to replace --initial-delay and then be consistent with stat's
--delay equivalent option.

perf record: Add --initial-delay option

2014-01-13T13:07:03+00:00

perf stat has a --delay option to delay measuring the workload.

This is useful to skip measuring the startup phase of the program, which
is often very different from the main workload.

The same is useful for perf record when sampling.

--no-delay was already taken, so add a --initial-delay
to perf record too.
-D was already taken for record, so there is only a long option.

v2: Don't disable group members (Namhyung Kim)
v3: port to latest perf/core
    rename to --initial-delay to avoid conflict with --no-delay
