6.60.19 Other MIPS Built-in Functions

GCC provides other MIPS-specific built-in functions:

void __builtin_mips_cache (int op, const volatile void *addr)
+

Insert a ‘cache’ instruction with operands op and addr. GCC defines the preprocessor macro ___GCC_HAVE_BUILTIN_MIPS_CACHE when this function is available.

unsigned int __builtin_mips_get_fcsr (void)
void __builtin_mips_set_fcsr (unsigned int value)
+

Get and set the contents of the floating-point control and status register (FPU control register 31). These functions are only available in hard-float code but can be called in both MIPS16 and non-MIPS16 contexts.

__builtin_mips_set_fcsr can be used to change any bit of the register except the condition codes, which GCC assumes are preserved.
