Hi Mark, Artyom,
I'm looking at the CPU_FEATURE_FLOAT128 definition introduced
in commit 64a88d5d3a ("CPU feature selection support"). Any
clue how it was supposed to be used?
Thanks,
Phil.

This should have a comment like
/*
* Qemu is emulating the linux kernel, which will
* trap and emulate float128 instructions.
*/
