Rémi Denis-Courmont	b95e2fbd85	lavu/cpu: detect RISC-V base extensions This introduces compile-time and run-time CPU detection on RISC-V. In practice, I doubt that FFmpeg will ever see a RISC-V CPU without all of I, F and D extensions, and if it does, it probably won't have run-time detection. So the flags are essentially always set. But as things stand, checkasm wants them that way. Compare the ARMV8 flag on AArch64. We are nowhere near running short on CPU flag bits.	2 years ago

lavu/cpu: detect RISC-V base extensions

This introduces compile-time and run-time CPU detection on RISC-V. In
practice, I doubt that FFmpeg will ever see a RISC-V CPU without all of
I, F and D extensions, and if it does, it probably won't have run-time
detection. So the flags are essentially always set.

But as things stand, checkasm wants them that way. Compare the ARMV8
flag on AArch64. We are nowhere near running short on CPU flag bits.
