8.3 SPARC options
On the SPARC range of processors the -mcpu=CPU option
generates processor-specific code. The valid options for
CPU are v7, v8 (SuperSPARC),
Sparclite, Sparclet and v9 (UltraSPARC). Code
produced with a specific -mcpu option will not run on other
processors in the SPARC family, except where supported by the
backwards-compatibility of the processor itself.
On 64-bit UltraSPARC systems the options -m32 and -m64
control code generation for 32-bit or 64-bit environments. The 32-bit
environment selected by -m32 uses int, long and
pointer types with a size of 32 bits. The 64-bit environment selected by
-m64 uses a 32-bit int type and 64-bit long and
pointer types.
