Extend the CLANG38 toolchain definition so it can be used for
ARM and AARCH64 as well. Note that this requires llvm-ar and
the LLVMgold.so linker plugin.
In preparation of doing the same for GCC5, this toolchain version
also departs from the custom of using -O0 for DEBUG builds, which
makes them needlessly slow. Instead, let's add a NOOPT flavor as
well, and enable optimization for DEBUG like the other architectures
do. (Note that this will require some trivial changes to the platform
description files)

I'm just curious about one thing: what decides if a -Wno... option goes into CLANG38_WARNING_OVERRIDES? You left some -Wno... options out of it (kept them explicitly in the CLANG38_ALL_CC_FLAGS define). ... It seems like the CLANG38_ALL_CC_FLAGS is not used for the ARM / AARCH64 toolchains. "ALL" becomes sort of a misnomer then. Is that OK?

I reluctantly added the -Wno-varargs option, for instance, because we didn't need that for Clang 3.5, but more recent Clang chokes on some questionable uses in EDK2, e.g., /home/ard/build/edk2/MdePkg/Library/UefiLib/UefiLib.c:1530:19: error: passing an object that undergoes default argument promotion to 'va_start' has undefined behavior [-Werror,-Wvarargs] VA_START (Args, Iso639Language); ^ /home/ard/build/edk2/MdePkg/Library/UefiLib/UefiLib.c:1517:19: note: parameter of type 'BOOLEAN' (aka 'unsigned char') is declared here IN BOOLEAN Iso639Language, ^ 1 error generated. So indeed, I tried to be conservative in disabling warnings. > >>> ... It seems like the CLANG38_ALL_CC_FLAGS is not used for the ARM / >>> AARCH64 toolchains. "ALL" becomes sort of a misnomer then.

Hi Ard, I'm OK for the patch. BTW, would you mind to help add the "-Wno-unused-const-variable" in the CLANG38_WARNING_OVERRIDES? I happen to need add it in CLANG38 (https://bugzilla.tianocore.org/show_bug.cgi?id=790) and I see it seems a shared flag for ARM/AARCH64 as well.

I happen to need add it in CLANG38 (https://bugzilla.tianocore.org/show_bug.cgi?id=790) and I see it seems a shared flag for ARM/AARCH64 as well. I suggest we handle that flag / BZ separately from this patch. (If Ard feels very generous, he could append a separate patch to this series, for adding the flag, but I don't think we can *ask* for that. It's a totally separate topic.) Thanks!
