Arguments
- keyword
- The only supported value for this argument isspir64.When you specifyspir64, the compiler generates an x86 + SPIR64 (64-bit Standard Portable Intermediate Representation) fat binary for Intel® GPU devices.
Default
- OFF
- If this option is not specified, no x86 + SPIR64 fat binary is created.
Description
This option enables offloading to a specified GPU target if OpenMP* features
have been enabled.
To use this option, you must enable recognition of
OpenMP* features by specifying one of the following options:
- [q or Q]openmp
- -fiopenmp(Linux*) or/Qiopenmp(Windows*)
- -fopenmp(deprecated; it is equivalent to-qopenmpon Linux*)
The following shows an example:
icx (or icpx) -fiopenmp -fopenmp-targets=spir64 matmul_offload.cpp -o matmul
When you specify
-fopenmp-targets
(Linux*) or
/Qopenmp-targets
(Windows*), C++ exception handling is
disabled for target compilations.
For host compilations on Linux* systems, if you want to
disable C++ exception handling, you must specify option
-fno-exceptions
.
