Is it possible to compile sycl host code to ARM arch?

[harishch4]

So as mentioned in the title, I'm trying compile SYCL host code to ARM, my intial thought is to pass --target flag to -fsycl-host-compiler-options. However, I'm facing below error while compiling a sycl code (cuda code converted to SYCL via SYCLomatic).

$ clang++ -fsycl -fsycl-host-compiler="clang++" -fsycl-host-compiler-options="--target=aarch64-none-eabi" vector_add.dp.cpp

In file included from :1:

However, if I run the same command without -fsycl-host-compiler and -fsycl-host-compiler-options, it works but for x86_64.

@harishch4, if you can use clang++ as you host compiler, it's easier use regular mode (i.e. don't use -fsycl-host-compiler* options).

If you wish to use an alternative host compiler, you should know that certain features won't work, and this configuration is not tested. You haven't provided the code you tried to compile, but I suspect it uses "unnamed" kernels, which requires host compiler to support non-standard intrinsic. You can try using named kernels to fix this problem.
