pwr2s
p2sc
You can run the executable file on any desktop implementation of the
POWER2 Chip. This architecture belongs to the -qarch=pwr2 group.
You can run the executable file on any POWER2 Super Chip hardware
platform. The POWER2 Super Chip belongs to the -qarch=pwr2 group.
601 You can run the executable file on any PowerPC 601 ® hardware platform.
Because the PowerPC 601 processor implements some instructions that are
not present in other PowerPC implementations, programs might not run
on other PowerPC processors. The rndsngl suboption of the -qfloat option
is automatically turned on and cannot be turned off.
603 You can run the executable file on any PowerPC 603 ® hardware platform.
Because the PowerPC 603 processor implements some instructions that are
not present in other PowerPC implementations, such as the optional
PowerPC graphics instructions, programs might not run on other PowerPC
processors. The rndsngl suboption of the -qfloat option is automatically
turned on and cannot be turned off.
604 You can run the executable file on any PowerPC 604 ® hardware platform.
Because the PowerPC 604 processor implements some instructions that are
not present in other PowerPC implementations, such as the optional
PowerPC graphics instructions, programs might not run on other PowerPC
processors. The rndsngl suboption of the -qfloat option is automatically
turned on and cannot be turned off.
ppc
ppcgr
ppc64
You can run the executable file on any PowerPC hardware platform,
including those that are based on the RS64I, RS64II, RS64III, 601, 603,
604, POWER3, POWER4, POWER5, PowerPC 970, and future PowerPC
chips. If you specify the compiler option -q64, the target platform is 64-bit
PowerPC, and the compiler silently upgrades the -qarch setting to ppc64.
See “Using XL Fortran in a 64-Bit Environment” on page 279 for details.
The rndsngl suboption of the -qfloat option is automatically turned on and
cannot be turned off.
In 32-bit mode, produces object code that may contain optional graphics
instructions for PowerPC hardware platforms.
In 64-bit mode, produces object code containing optional graphics
instructions that will run on 64-bit PowerPC platforms, but not on
32-bit-only platforms, and the -qarch option will be silently upgraded to
-qarch=ppc64gr.
You can run the executable file on any 64-bit PowerPC hardware platform.
This suboption can be selected when compiling in 32–bit mode, but the
resulting object code may include instructions that are not recognized or
behave differently when run on PowerPC platforms that do not support
64-bit mode.
ppc64gr
You can run the executable file on any 64-bit PowerPC hardware platform
that supports the optional graphics instructions.
ppc64grsq
You can run the executable file on any 64-bit PowerPC hardware platform
that supports the optional graphics and square root instructions.
rs64a
rs64b
You can run the executable file on any RS64I machine.
You can run the executable file on any RS64II machine.
