Currently the control word is in the low 16-bits and the status word is in the high 16 bits. The status word contains the flags to show if an exception has occurred. However, the SSE2 mscsr register has the exception flags in the low part of the register. For consistency, put the status word in the low 16-bits of the result to match more closely what SSE2 does. This simplifies debugging when looking at the the x87 and sse2 modes independently. - - - - - ab7cfc59 by Raymond Toy at 2024-09-03T06:21:12-07:00 Clean up indentation; add a few comments. - - - - - c0f457a2 by Raymond Toy at 2024-09-03T07:22:59-07:00 Oops.

Also add functions to set the modes in the sigcontext. Make these available to Lisp. Use these functions in sigfpe-handler to examine the modes and to clear out the current exception. Still needs work.
