Intrinsic benchmarks & Performance tracing #52

Closed ralfbiedert closed 6 years ago

ralfbiedert commented 6 years ago

Changes:

Added intrinsic benchmarks as mentioned in #51
Moved benchmarks to benches for better clarity and control of #![feature(stdsimd)]
Implemented performance logging #48 (--feature trace), looks like this:

test arch::x86::intrin::sum::tests::test_packed_sum_i64x8 ... ok
🚄 faster is using HARDWARE acceleration here (src/arch/x86/intrin/sum.rs:56).
⛔ faster is using SOFTWARE emulation here (src/arch/x86/intrin/sum.rs:259).
🚄 faster is using HARDWARE acceleration here (src/arch/x86/intrin/sum.rs:168).
🚄 faster is using HARDWARE acceleration here (src/arch/x86/intrin/cmp.rs:21).

Added ability to configure performance trace log file (e.g., for mobile / embedded development) with environment variable FASTER_DEBUG_FILE if feature trace is set.
