Option
for the Intel® Itanium® 2 Processor
The Intel® Itanium® compilers now feature optimized instruction
scheduling for the Itanium 2 processor.
More functional units and lower latencies reduce nops
and instruction group boundaries (also called "stop bits"). This reduction
in nops and stop bits allows more complete filling
of bundles, fewer nops resulting from resource
starvation. Consequently, more instructions are used effectively during
each cycle.
To specify scheduling optimizations for the Itanium 2 processor, use
the following option:
- Microsoft* Windows*: -G2
- Linux*: -tpp2
There are no new instructions for the Itanium 2 processor.
