question about armclang support

[Tan, Sau Kae]

Hi All,

May I know is armclang already supported in EDK2?
Or only armcc is supported currently?
Thanks.

Regards,

Looking at "BaseTools/Conf/tools_def.template", the following toolchains appear supported for both ARM and AARCH64:
- CLANG35
- CLANG38

They are documented (in the same file) as:

#   CLANG35     -Linux,Windows-  Requires:
#                             Clang v3.5 or later, and GNU binutils targeting aarch64-linux-gnu or arm-linux-gnueabi
#                        Optional:
#                             Required to build platforms or ACPI tables:
#                               Intel(r) ACPI Compiler from
#                               https://acpica.org/downloads
#   CLANG38  -Linux-  Requires:
#                             Clang v3.8, LLVMgold plugin and GNU binutils 2.26 targeting x86_64-linux-gnu, aarch64-linux-gnu or arm-linux-gnueabi
#                             Clang v3.9 or later, LLVMgold plugin and GNU binutils 2.28 targeting x86_64-linux-gnu, aarch64-linux-gnu or arm-linux-gnueabi
#                        Optional:
#                             Required to build platforms or ACPI tables:
#                               Intel(r) ACPI Compiler from
#                               https://acpica.org/downloads

I suppose ARMCLANG is the commercial ARM compiler based on LLVM/CLANG?

In that case, could you please share your experiences with these
toolchain profiles? CLANG3x support was added primarily to ensure the
code base is supported by ARMCLANG but I don't know whether anyone has
actually tried building it like that.
