| #define cache_op | ( | op, | |
| linesize | |||
| ) |
Helper macro to perform cache refresh operations.
| [in] | op | Operation to perform |
| [in] | linesize | Size of a cacheline in bytes |
| void __init_cop1 | ( | void | ) |
Initialize COP1 with default settings that prevent undesirable exceptions.
Enable FPU exceptions that can help programmers avoid bugs in their code. Underflow exceptions are not enabled because they are triggered whenever a denormalized float is generated, even if the FS bit is set (see below). So basically having the underflow exception enabled seems to be useless unless also the underflow (and the inexact) exceptions are off. Notice that underflows can happen also with library code such as tanf(BITCAST_I2F(0x3f490fdb)) (0.785398185253).
| int __bootcic = 6102 |
Boot CIC.
Defaults to 6102.
