The power9 (running PowerPC ISA 3.0) has a round to integer instruction
(XSRQPI) that does various flavors of round an IEEE 128-bit floating point to
integeral values. This patch adds the support to the machine independent
portion of the compiler, and adds the necessary support for ceilf128,
roundf128, truncf128, and roundf128 to the PowerPC backend when you use
-mcpu=power9.
I have done bootstrap builds on both x86-64 and a little endian power8 system.
Can I install these patches to the trunk?
