如何为x86软浮点或无浮点单元(fpu)编译glibc

I have a x86 core which does not support floating point unit (FPU), and i am writing a micro kernel for floating point calculations such as add, div, mul, pow, log etc. As per need i must use static library for doing float calculations. I found to use glibc (from GNU) which has math library. It means I will have to compile glibc with “-msoft-float” compiler switch or ‘without-fp’. After doing search in stackoverflow.com I found glibc can be compiled by sequence of command like given below (from link - I have a x86 core which does not support floati
