Dear professionals, I'm Jake, a Java developer. I'm currently working on adapting code related to JDK 8 instructions f2xm1 and fyl2x, along with 80-bit extended precision implementation, to the ARM architecture. I'm wondering if there are alternative instructions for f2xm1 and fyl2x in the ARM architecture, and how to achieve 80-bit extended precision there. Could you please share any relevant knowledge or reference materials? Your help would be highly appreciated. Thank you!
On ARM host, https://github.com/openjdk/jdk/blob/jdk8-b120/hotspot/src/cpu/x86/vm/macroAssembler_x86.cpp#L2269 please check the link. That is the part we cannot get the same result from.
