Aurelien Jarno 988902fc3b tcg/mips: detect available host instructions at runtime ... Now that TCG supports enabling and disabling ops at runtime, it's possible to detect the available host instructions at runtime, and enable the corresponding ops accordingly. Unfortunately it's not easy to probe for available instructions on MIPS, the information is partially available in /proc/cpuinfo, and not available in AUXV. This patch therefore probes for the instructions by trying to execute them and by catching a possible SIGILL signal.
