ftarget-compile-fast
Tells the compiler to perform less aggressive optimizations to reduce compilation time at the expense of generating less optimal target code. This is an experimental feature.
Syntax

-ftarget-compile-fast |
Windows: |
/ftarget-compile-fast |
Arguments
None
Default
OFF |
Less aggressive optimizations to reduce compilation time are not performed. |
Description
This option tells the compiler to perform less aggressive optimizations to reduce compilation time at the expense of generating less optimal target code. This is an experimental feature.
It may be useful to specify this option in these cases:
When you are in a development period and want a fast turnaround time while testing
When you are specifying options O2 or O3 for a product with Just-in-Time (JIT) compilation, and both compile-time and execution performance are important
This option is not recommended when you are specifying options O2 or O3 for a product with Ahead-of-Time (AOT) compilation, where long but one-time compilation may be tolerable in order to achieve the best performance.
This compiler option is not recommended if you plan to ship object files as part of a final product.
This option only applies to host compilation. When offloading is enabled, it does not impact device-specific compilation.

ifx -fiopenmp -fopenmp-targets=spir64 -ftarget-compile-fast foo.F90 -o a.out
Windows
ifx /Qiopenmp /Qopenmp-targets=spir64 /ftarget-compile-fast foo.F90 /object:a.out
