This patch moves the settings related migration-test from the migration-test.c file to a seperate header file. It also renames the x86-a-b-bootblock.s file extension from .s to .S, allowing gcc pre-processor to include the C-style header file correctly. Signed-off-by: Wei Huang

As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not

[Qemu-devel] [PULL 22/22] fpu/softfloat: re-factor sqrt

This is a little bit of a departure from softfloat's original approach as we skip the estimate step in favour of a straight iteration. There is a minor optimisation to avoid calculating more bits of precision than we need however this still brings a performance drop, especially for float64
