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.

NOTE:

When using this option, you must also specify option -fsycl.

If you specify -fno-sycl-early-optimizations, these optimizations are disabled.

For information about available SYCL drivers, refer to Invoke the Compiler.

NOTE:

When SYCL offloading is enabled, this option only applies to device-specific compilation.
