Some benchmark suites contain test cases that have nonreproducible behaviour. This is mostly caused by relying on "now" when dealing with dates or timestamps, instead of using a fixed moment. (A notorious example is the crypto-aes.js test case of the sunspider bechmark suite, where the heap memory consumption can vary between 34K-41K heap because of using `(new Date()).getTime()`.) This commit renames the jerry-minimal command line tool to jerry-test (to better reflect its purpose) and adds extra code, which intercepts some calls to libc (`gettimeofday`, `rand`) and pins their results to some fixed values. This makes the tool useless in a general case but ensures stable results when benchmarking -- for which it is mostly used. As a side effect, the commit also changes jerry-libc by making all libc functions weak symbols to allow their override from application code.

JerryScript: JavaScript engine for the Internet of Things
JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.
Key characteristics of JerryScript:
- Full ECMAScript 5.1 standard compliance
- 160K binary size when compiled for ARM Thumb-2
- Heavily optimized for low memory consumption
- Written in C99 for maximum portability
- Snapshot support for precompiling JavaScript source code to byte code
- Mature C API, easy to embed in applications
Additional information can be found on our project page and Wiki.
Memory usage and Binary footprint are measured at here with real target daily.
The following table shows the latest results on the devices:
| STM32F4-Discovery |  |
|---|---|
| Raspberry Pi 2 |  |
