FlushInstructionCache

Header: OSUtils.h Carbon status: Unsupported

Flushes the current contents of the instruction cache.

void FlushInstructionCache ();
DISCUSSION

Because flushing this cache degrades performance of the CPU, you should call this routine only when absolutely necessary.

On processors with a copy-back data cache, FlushInstructionCache also flushes the data cache before it flushes the instruction cache, to ensure that any instructions subsequently copied to the instruction cache are not copied from stale RAM.

CARBON NOTES

68K-specific. Use MakeDataExecutable on PowerPC machines.
