This benchmark also includes the measuring of RSS.
Bug: 137795072
Test: Ran different iterations and verified the RSS_MB value is nearly
Test: identical no matter the number of iterations.

Update the native allocator documentation to include running of this
benchmark.
Move the malloc_benchmark.cpp to malloc_sql_benchmark.cpp and use
malloc_benchmark.cpp for benchmarking functions from malloc.h.
Bug: 137795072
Test: Ran new benchmark.

Just to sanity check that toupper/tolower and towupper/towlower are in
the same ballpark for the ASCII range.
Test: ran benchmarks

Remove the need to add every benchmark to the list of all benchmarks.
Also, add some hard-coding of the location of the benchmark executable.
Add a test to make sure the benchmark exists so it's possible to detect
if the executable changes location.
Finally, make the tests isolated so that they finish in half the time.
Test: Ran unit tests.

Add benchmarks for mallinfo, and for retrieving RSS from
/proc/self/statm, since we're considering using these for GC
triggering.
Add some static linkage specifiers, after running into a build
problem due to a spurious conflict.

It should be possible to run the benchmarks on any device, including
past and future ones, and sticking to NDK libraries ensures that.
Bug: N/A

This runs through the trace of the allocations in a sql benchmark app
executed in the benchmark thread.
Add one benchmark with decay time set to 0 and another with decay time
set to 1.
Include a script that can generate a header file that can be used to
regenerate the data.

Test: Builds, ran unit tests, ran benchmarks.

1. fix all_benchmarks. Some new benchmarks were added.
2. move some benchmark suites to the right place.
3. add unit test for https://android-review.googlesource.com/c/platform/bionic/+/724785
Test: compile and run bionic-benchmarks-tests on device.

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
program, and is generally not recommended or even supported. This
change moves the actual logic for system properties into a class that
can be tested in isolation, without reinitializing the actual system
property area used in libc.
Bug: 62197783
Test: boot devices, ensure properties work
Test: system property unit tests and benchmarks

Instead of requiring the need to maintain a list of all the benchmarks,
add a programmatic way to generate all of the benchmarks.
This generation runs the benchmarks in alphabetical order.
Add a new macro BIONIC_BENCHMARK_WITH_ARG that will be the default argument
to pass to the benchmark. Change the benchmarks that require default arguments.
Add a small example xml file, and remove the full.xml/host.xml files.
Update readme.
Test: Ran new unit tests, verified all tests are added.

libdl is part of system_shared_libs now. -ldl -lpthread -lm are now defaults
for host_ldlibs on Linux and Darwin. -lrt is a default for host_ldlibs on
Linux.
Test: m host
Test: mmma bionic

- Add a default xml file to run if nothing is specified on the command-line.
- Add a way to specify a xml file in suites without having to specify the
full path name.
- Move all of the test xml files into their own directory.
- Add the suites directory for to glibc benchmarks.
- Add a new test for help data.
- Modify the full suite test to verify the default xml is chosen and use
the real full.xml instead of the test one. Delete the test_full.xml.
- Move the property tests to the end of the suite.
- Add skipping of xml comments.
Test: Ran the unit tests and ran the bionic benchmarks.

The intent here is to confirm that the compiler behaves as expected,
and to guide optimization efforts, particularly where there is a
choice between primitives.
Test: Built and ran benchmark on Angler repeatedly. Manually confirmed
that the compiler behaves roughly as expected.

The compile-time tests and a few custom libraries for dynamic linker
testing are still compiled in make.
Also converts the make rules to run tests on the host to shell scripts
in tests/run-on-host.sh and benchmarks/run-on-host.sh
