[PATCH v2 0/6] softfloat, target/i386: fprem, fprem1 fixes

2020-06-08 Thread Joseph Myers
The x87 floating-point emulation of the fprem and fprem1 instructions works via conversion to and from double. This is inherently unsuitable for a good emulation of any floatx80 operation. This patch series adapts the softfloat floatx80_rem implementation to be suitable for these instructions and
