fsycl-early-optimizations
Enables LLVM-related optimizations before
SPIR-V* generation.
Syntax
Linux:
-fsycl-early-optimizations
-fno-sycl-early-optimizations
Windows:
-fsycl-early-optimizations
-fno-sycl-early-optimizations
Arguments
None
Default
- ON
- LLVM-related optimizations are enabled before SPIR-V* generation.
Description
This option enables LLVM-related optimizations before SPIR-V* generation.
These optimizations can improve performance.
If you specify
-fno-sycl-early-optimizations
, these optimizations are
disabled.
When using the icx/icpx compiler driver for option
-fsycl-early-optimizations
, you must also specify option
-fsycl
.
When using the dpcpp compiler driver, option
-fsycl
is implied by default.
When SYCL offloading is enabled, this option only
applies to device-specific compilation.
