We haven't done a large amount of testing with the builtins library for powerpc64le, but it has worked well for the work we have done. I don't know why cmake doesn't have options for it

I'm building compiler-rt in a ppc64le machine and it is generating the sanitizers fine but it is not generating the builtin library. I tried to compile it in a x8664 machine and I got the builtin library generated (libclangrt.builtins-x8664.a). Taking a look in a cmake config file from compiler-rt, I saw that ppc64 is not in the supported architecture list to generate the builtin library: set(ALLBUILTINSUPPORTEDARCH X86{X86} X86{X8664} ARM32{ARM32} ARM32{ARM64} ${MIPS32} MIPS64{MIPS64} MIPS64{WASM32} ${WASM64})

But in compiler-rt webpage (https://compiler-rt.llvm.org/), under "Platform Support", says: "builtins is known to work on the following platforms: - Machine Architectures: i386, X86-64, SPARC64, ARM, PowerPC, PowerPC 64." Shouldn't the builtin library be built in ppc64 or I am missing something? Thanks, Roberto Oliveira
