|Subject:||help required for floating point support for motorolla PowerPC 8240|
|Date:||Mon, 12 Feb 2001 12:16:04 +0530|
i am developing one application for motorolla PowerPC 8240 which supports Hardware FPU. I am using tornado version 2.0 as developing environment . what i did is , i had implemented floating point instruction using "C" ( e.g float1 = float2 / 2.3 ; )
and generate the code for the same. i want to have hardware floating point support for the that.
As i need to have hardware floating point support, i found one flag value for the same is "-msoft-float" / "-mhard-float".i implemented this value in ADDED_CFLAGS in makefile(attached). after building the code , i check the assembly instruction. While builing from the tornado i can see the value added in flag been used (on output screen) but still i could not see use of any hardware floating point instruction. If anywhere else change is required please suggest.
so please suggest that how i can proceed.
