* | avutil/arm/intmath: return int for uint8 / uint16 clipMichael Niedermayer2015-07-20
| | | | | | | | | | | | | | | | | | | | The C functions return uint8/16_t but that is effectively int not unsigned int Fixes fate-filter-tblend We do not return uint8/16_t as that would require the compiler to truncate the values, slowing it down.

| | | | | | | | | | | | | | | | Recent ICC versions that define GCC as >= 4.5 (like ICC 13) apparently can't optimize the generic C versions of av_bswap*() on their own. Reviewed-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: James Almer <jamrial@gmail.com>

|\| | | | | | | | | | | | | * commit 'd1a6cb195f610978ba5d2351e60f938f7f261d59': x86: Serialize rdtsc in read_time() Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * x86: Serialize rdtsc in read_time()Henrik Gramner2015-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| | | | | | | | | | | | | | | | | | When compiling libavutil/internal.h as C++11, clang warns that a space is required between a string literal and an identifier.
