The description of memory_replay talks about unzippping the trace
files, but this is no longer necessary. This language has been
updated to reflect this.

To generate these traces, see the [Malloc Debug documentation](https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README.md),
the option [record\_allocs](https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README.md#record_allocs_total_entries).
To run these benchmarks, first copy the trace files to the target and
unzip them using these commands:
To run these benchmarks, first copy the trace files to the target using
these commands:
adb shell push system/extras/traces /data/local/tmp
adb shell 'cd /data/local/tmp/traces && for name in *.zip; do unzip $name; done'
Since all of the traces come from applications, the `memory_replay` program
will always call `mallopt(M_DECAY_TIME, 1)' before running the trace.
Run the benchmark thusly:
adb shell memory_replay64 /data/local/tmp/traces/XXX.txt
adb shell memory_replay32 /data/local/tmp/traces/XXX.txt
adb shell memory_replay64 /data/local/tmp/traces/XXX.zip
adb shell memory_replay32 /data/local/tmp/traces/XXX.zip
Where XXX.txt is the name of a trace file.
Where XXX.zip is the name of a zipped trace file. The `memory_replay`
program also can process text files, but all trace files are currently
checked in as zip files.
Every 100000 allocation operations, a dump of the RSS and VA space will be
performed. At the end, a final RSS and VA space number will be printed.
