 * detect 32-bit parameters being used as if they were 64-bit in x86-64

Compile by running 'make checkasm'.
Execute by running 'tests/checkasm/checkasm'.

Optional arguments are '--bench' to run benchmarks for all functions,
'--bench=<pattern>' to run benchmarks for all functions that starts with
<pattern>, and '<integer>' to seed the PRNG for reproducible results.

Loosely based on code from x264. Currently only supports x86 and x86-64,

Note that functions with floating point parameters or floating point

5 years agox86: Serialize rdtsc in read_time()
Henrik Gramner [Wed, 8 Jul 2015 20:33:53 +0000 (22:33 +0200)]
x86: Serialize rdtsc in read_time()

Improves the accuracy of measurements, especially in short sections.

To quote the Intel 64 and IA-32 Architectures Software Developer's Manual:
"The RDTSC instruction is not a serializing instruction. It does not necessarily
wait until all previous instructions have been executed before reading the counter.
Similarly, subsequent instructions may begin execution before the read operation
is performed. If software requires RDTSC to be executed only after all previous
instructions have completed locally, it can either use RDTSCP (if the processor
supports that instruction) or execute the sequence LFENCE;RDTSC."

SSE2 is a requirement for lfence so only use it on SSE2-capable systems.
Prefer lfence;rdtsc over rdtscp since rdtscp is supported on fewer systems.
