This was broken by all the mainline modules stuff. It's quite a bit
hairier to set up now, given that we don't have an apexd on the host.
An alternative might be to actually set up a fake /apex that points to
the bootstrap directories?

Adding some benchmarks that keep a certain number of allocation
around. This benchmark should not be used as an absolute for determining
what is a good/bad native allocator. However, it should be used to make
sure that numbers are not completely changed between allocator versions.
Also update the malloc sql benchmark to match the same style as these
new benchmarks.

As for exp/exp2 benchmark, this patch add two benchmark for pow:

Similar to exp/exp2, this patch add two benchmarks for log and log2:
one which measures thoughput and one which measures latency.
The input data is based on logf/log2f one (reduced trace based on 2.8

This patch add two benchmarks for both exp and exp2, one which measures
thoughput and one which measures latency. The latency benchmark works by
creating a dependency on the previous iteration and with a zero multiply
to avoid changing the input value.
The input is based on expf/exp2f benchmark (reduced trace based on 2.4
billion samples extracted from specpu2017 521.wrf_r benchmark).
Test: ran 32-bit and 64-bit x86 tests on host
Similar to expf/exp2f, this patch add two benchmarks for sinf, cosf, and

Add a hand-rolled maps line parser as something to compare our realistic
sscanf benchmark against. Also add benchmarks for the ato*/strto* family.
This patch doesn't fix the tests, which seem to have been broken by
the recent google-benchmark upgrade despite the benchmarks themselves
all working just fine. To me that's a final strike against these tests
which are hard to maintain and not obviously useful, but we can worry
about what to do with them -- whether to just delete them or to try to
turn them into tests that actually have some value -- in a separate CL.

Reinitializing system properties can result in crashes later in the
