General informations

The Linux kernel configuration item CONFIG_SUPPORT_DENORMAL_ARITHMETIC:

• prompt: Denormal arithmetic support
• type: bool
• depends on: CONFIG_FPU
• defined in arch/nds32/Kconfig.cpu
• found in Linux kernels: 5.0–5.17, 5.17+HEAD

Help text

Say Y here to enable arithmetic of denormalized number. Enabling this feature can enhance the precision for tininess number. However, performance loss in float point calculations is possibly significant due to additional FPU exception.

If the calculated tolerance for tininess number is not critical, say N to prevent performance loss.
