>>Building libgcc is not optional. It is required for all targets. So, irrespective whether i provide floating point implementation by soft-fp, fpu-bit or ieeelib, an error free libgcc build is a MUST? What if I dont want to generate calls to libgcc.a but want want gcc to generate inline code?

Hi all, I am trying to provide soft-fp support to a an 18-bit soft-core processor architecture at my university. But the problem is that libgcc has not been cross-compiled for my target architecture and some functions are missing so i cannot build libgcc.I believe soft-fp is compiled in libgcc so i

Hi, I am working on an 18-bit opensource soft-core processor at my university. My task is to emulate floating point operation since there is no hardware unit for float operations. I have the cross compiler and binutils for my target. But upon calling atest program, it gives the following error: :
