If this is true for the floating point functions too, it's possible that moving the code into a 'normal' compilation unit will break this mechanism.
These functions were declared weak, so any other instance inside the project will replace them without error. ----- Ursprüngliche Nachricht ----- Von: Diane Gagne An: [email protected] Gesendet am: 09 Jun 2010 23:35:56 Betreff: [Mspgcc-users] Help with floating point multiplication I am trying to make a faster version of the floating point multiplier. When I look at the .lst source of a test function calling floating point multiplication it calls the function __mulsf3. When I copy the code from the file mulsf.c into a separate function of mine it does not tell me when the answer is overflow anymore. From this, I think there must be another function called __mulsf3 that I do not see. I was wondering where that function was in the files, or else how the overflow was seen when using the float multiplication. I am using a Linux computer with the makefile in the packaging directory to build the compiler. _______________________________________________ Mspgcc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mspgcc-users
