m32, m64, Qm32, Qm64
Tells the compiler to generate code for a specific architecture. Option m32 (and Qm32) is deprecated and will be removed in a future release. 32-bit options are only available for ifort.
Syntax
Linux: |
-m32 (ifort only) -m64 |
macOS: |
-m32 (ifort only) -m64 |
Windows: |
/Qm32 (ifort only) /Qm64 |
Arguments
None
Default
ifort: OFF |
The compiler's behavior depends on the host system. |
On ifx: -m64 or /Qm64 |
The compiler generates code for Intel® 64 architecture. |
Description
These options tell the compiler to generate code for a specific architecture.

-m32 or /Qm32 |
Tells the compiler to generate code for IA-32 architecture. IA-32 support is deprecated and will be removed in a future release. 32-bit options are only available for ifort. |
-m64 or /Qm64 |
Tells the compiler to generate code for Intel® 64 architecture. |
For ifort, the -m64 option is the same as macOS option -arch x86_64. This option is not related to the Intel® Fortran Compiler option arch.
On Linux* systems, these options are provided for compatibility with gcc.
This option only applies to host compilation. When offloading is enabled, it does not impact device-specific compilation. Offloading can only be enabled when using ifx.
