#     powerpc: Work around inline asm issues in alternate feature sections
#     
#     The clang toolchain treats inline assembly a bit differently than
#     straight assembly code. In particular, inline assembly doesn't have
#     the complete context available to resolve expressions. This is
#     intentional to avoid divergence in the resulting assembly code.
#     
#     We can work around this issue by borrowing a workaround done for ARM,
#     i.e. not directly testing the labels themselves, but by moving the
#     current output pointer by a value that should always be zero. If this
#     value is not null, then we will trigger a backward move, which is
#     explicitly forbidden.
