Dear Timur Tabi,
In message 4D3F16C7.7040000@freescale.com you wrote:
But when will gcc generate FP instructions? If we compile with soft-float, will it link in an FP library and use it?
GCC will (in addition to the obvious case of operations of FP data types) generate FP instructions for a number of "small data copy" operations, like assignment of structs etc.
My point is that compiling with soft-float doesn't make much more sense than compiling with hard-float, since there won't be any floating point instructions in either case.
You are wrong.
Best regards,
Wolfgang Denk
