<pre>FreeBSD's kernel exception handler code has fragments like:
REG_S a3, CALLFRAME_RA + KERN_REG_SIZE(sp) # for debugging
which expands though a bunch of macros to this on mips64:
sd $7, (((8 * 4) - 1 * 8) + (40 * 8))($29) # for debugging
clang with integrated assembler throws this error:
../../../mips/mips/exception.S:467:27: error: '(' expected
sd $7, ((8 * 4) - 1 * 8) + (40 * 8)($29) # for debugging
^
../../../mips/mips/exception.S:467:27: error: unexpected token in argument list
sd $7, ((8 * 4) - 1 * 8) + (40 * 8)($29) # for debugging
^
I've tried adding parenthesis around the macros, but the result is the same
failure to handle the +.</pre>
