Hi,
We are using a gcc 2.96 20000731 (Red Hat Linux 7.1 2.96-99.1) GCC cross-compiler with -msoftfloat to use software floating point routines.
When we profied an application using the Linux Trace Toolkit, we observed that there were a lot of CpU (Co-processor unusable) exceptions. Some of the floating point routines ( eg. __floatdidf) expect values to be passed in floating point registers and take FP exceptions even though the application has been built with -msoftfloat. Is this a general MIPS/GCC issue? What is the status of softfloat for MIPS in GCC?
Thanks in advance.
Rajesh
