It does not necessarily\nwait until all previous instructions have been executed before reading the counter.\nSimilarly, subsequent instructions may begin execution before the read operation\nis performed. If software requires RDTSC to be executed only after all previous\ninstructions have completed locally, it can either use RDTSCP (if the processor\nsupports that instruction) or execute the sequence LFENCE;RDTSC.\"\n\nRDTSCP would accomplish the same task, but it's only available since Nehalem.\n\nThis change makes SSE2 a requirement to run checkasm.","Henrik Gramner",false],["d731de374461dca2a7ed344ce59463ce3ac00693","1ed1015336f6a462e9365b18ca61d9eb32e77fa2@gmail.com","Use prefixed yasm if cross compiling and available","Timothy Gu",true],["b6bf2fc66e1e945ee13626e8fcec788c0d90fb54","8e94f45bbbbbc60368f7fcf4e7e230985801e332@capellasystems.net","Add support for user-specified timecodes in SEI pic_timing (from Capella Systems)\n\nTEST!!!!!","Martin Belleau",true],["d23a31252c356ad9b0c2281f6acd403544147998","f50c3d99358ea82a8b218fd54f4518b8af3fb9ae@gmail.com","Merge branch 'plain' into 7mod","Neil",true]],"size":4,"ref":"refs/heads/7mod","head":"d23a31252c356ad9b0c2281f6acd403544147998"}
