Fix memory leak in hashmap_clear() not freeing hashmap_entry structs for each
of the remaining entries. Also NULL-out bucket list to prevent possible
double-free between hashmap__clear() and hashmap__free().
Running test_progs-asan flavor clearly showed this problem.
If a metric contains the duration_time event then the event is placed
outside of the metric's group of events. Rather than split the group,
make it so the duration_time is immediately after the group.

Use a hashmap between a char* string and a double* value. While bpf's
hashmap entries are size_t in size, we can't guarantee sizeof(size_t) >=
sizeof(double). Avoid a memory allocation when gathering ids by making 0.0
a special value encoded as NULL.
Suggested by Andi Kleen:
Add --metric-no-group that causes all events within metrics to not be
grouped. This can allow the event to get more time when multiplexed, but
may also lower accuracy.
Add --metric-no-merge option. By default events in different metrics may
be shared if the group of events for one metric is the

Metric groups contain metrics. Metrics create groups of events to

Add a basic floating point number test to expr.

so ltdc gate clk is null.
need change clks[PLL_VCO_SAI] to clks[PLL_SAI]
add CLK_IGNORE_UNUSED for ltdc to make sure clk not be freed by

Hi Suravee,
I love your patch! Yet something to improve:
[auto build test ERROR on kvm/linux-next]
[also build test ERROR on vhost/linux-next linus/master v5.7-rc4 next-20200507]
[cannot apply to linux/master]
