Differences between the 3 options for floating point ABI?

Posted by Gryo on 2016-10-31 11:59

What are the differences between them?
Also why some of the headers coming with the firmware pack of the stm32 serie i use require soft instead of hard?

thanks in advance.

Hi,

I have an STM32L4 and i use softfp on linux and hard on windows.
On Linux, i have just not compiled gcc to works with hard.

Soft don’t works.

I think theses parameters are to use better the chip. Some chip can use hardware to calculate float.
I don’t know why it not works with soft for me...

i believe one is completely software fp, the other redirects soft fp abi code to use the FPU, while the third generates pure floating point code without calling abi functions.
