#pragma softfp_linkage, #pragma no_softfp_linkage

These pragmas control software floating-point linkage.

#pragma softfp_linkage adds an implicit __softfp qualifier to all subsequent function declarations and definitions.

#pragma no_softfp_linkage removes any implicit __softfp qualifiers from all subsequent function declarations and definitions. Explicit __softfp qualifiers are still respected.

When using command-line options that enable software floating-point linkage, implicit __softfp qualifiers are added to each function.

Default

The default floating-point linkage type depends on the target FPU architecture.
