CONFIG_FP_HARDABI¶
Floating point Hard ABI
Type: bool
Help¶
This option selects the Floating point ABI in which hardware floating
point instructions are generated and uses FPU-specific calling
conventions.
Note: the option is disabled for Zephyr builds with TF-M, as TF-M
does not currently support building with Hard ABI, hence linking
Zephyr with TF-M libraries would not be possible.
Direct dependencies¶
!BUILD_WITH_TFM && <choice: Floating point ABI>
(Includes any dependencies from ifs and menus.)
