[PATCH v2] target/i386: reimplement fpatan using floatx80 operations

2020-06-22 Thread Joseph Myers
The x87 fpatan emulation is currently based around conversion to double. This is inherently unsuitable for a good emulation of any floatx80 operation. Reimplement using the soft-float operations, as for other such instructions. Signed-off-by: Joseph Myers --- Changes in version 2: adjust the
