This is needed to support recent hardware in the amdgpu DRM driver. The FPU code in that driver is not performance-critical, so only provide the minimal support. Signed-off-by: Samuel Holland <samuel.holland@sifive.com> Signed-off-by: Icenowy Zheng <uwu@icenowy.me>
Since it is not possible to incrementally add/remove extensions from the compiler's ISA string by appending arguments, any code that wants to modify the ISA string must recreate the whole thing.

RISC-V uses kernel_fpu_begin()/kernel_fpu_end() like several other architectures. Enabling hardware FP requires overriding the ISA string for the relevant compilation units. Signed-off-by: Samuel Holland <samuel.holland@sifive.com> Signed-off-by: Icenowy Zheng <uwu@icenowy.me>
