Hi,


I work in arm in an open source project called TF [1], and we support
compilation with clang.  We want to get rid of GNU tools when a clang
toolchain is used, but we found some problems when we try to use the
clang assembler:

         - .func, .endfunc and .struct  directives are not supported
         - substraction of relative labels doesn't produce absolute
           values

                 .if (. - \begin) > 32)

                 generates 'error: expected absolute expression' message

Is clang going to support these features?

Best regards,
