Offload Compilation, OpenMP*, and Parallel Processing Options

This section contains descriptions for compiler options that pertain to offload compilation, OpenMP*, or parallel processing. They are listed in alphabetical order.

  Enables function pointers and support for virtual functions for DPC++ kernels and device functions. This is an experimental feature. This content is specific to DPC++.
• fsycl-explicit-simd
  Enables or disables the experimental "Explicit SIMD" SYCL* extension. This is a deprecated option that may be removed in a future release. This content is specific to DPC++.
• fsycl-help
  Causes help information to be emitted from the device compiler backend. This content is specific to DPC++.
• fsycl-host-compiler
  Tells the compiler to use the specified compiler for the host compilation of the overall offloading compilation that is performed. This content is specific to DPC++.
• fsycl-host-compiler-options
  Passes options to the compiler specified by option fsycl-host-compiler. This content is specific to DPC++.
• fsycl-id-queries-fit-in-int
  Tells the compiler to assume that SYCL ID queries fit within MAX_INT. This content is specific to DPC++.
• fsycl-link
  Tells the compiler to perform a partial link of device binaries to be used with Field Programmable Gate Array (FPGA). This content is specific to DPC++.
• fsycl-link-targets
  Tells the compiler to link only device code. This is a deprecated option that may be removed in a future release. This content is specific to DPC++.
• fsycl-max-parallel-link-jobs
  Tells the compiler that it can simultaneously spawn up to the specified number of processes to perform actions required to link DPC++ applications. This is an experimental feature. This content is specific to DPC++.
• fsycl-targets
  Tells the compiler to generate code for specified device targets. This content is specific to DPC++.
• fsycl-unnamed-lambda
