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:
: In function `test': (.text+0x0): undefined reference to `__floatsisf' In function `test': : In function `test': (.text+0x2c): undefined reference to `__mulsf3' : In function `test': (.text+0x2e): undefined reference to `__fixsfsi' I realize there needs a machine dependent sfp-machine.h file and I have it for my architecture modified. Can anyone explain me the changes required to be make in the config.gcc file to link my target to soft-fp libraries? and do I need any more changes in gcc build? Thanks Sheheryar
