Subject: [PATCH] x86 (__HAVE_FLOAT128): Defined to 0 for Intel SYCL compiler
|
|
[BZ #32723]
|
|
|
|
Intel compiler always defines __INTEL_LLVM_COMPILER. When SYCL is
|
|
enabled by -fsycl, it also defines SYCL_LANGUAGE_VERSION. Since Intel
|
|
SYCL compiler doesn't support _Float128:
|
|
|
|
https://github.com/intel/llvm/issues/16903
|
|
|
|
define __HAVE_FLOAT128 to 0 for Intel SYCL compiler.
|
|
|
|
This fixes BZ #32723.
