Is that even legal?

So what would that work like?

                "por "MANGLE(d_idx)"(%0), %%mm1 \n" // nnz[b] || nnz[bn]

gives

/var/folders/Rz/RzQTCSLsFPWQeOEO5EXsJE+++TI/-Tmp-//ccNBPRga.s:341:junk
`(%rip)' after expression
/var/folders/Rz/RzQTCSLsFPWQeOEO5EXsJE+++TI/-Tmp-//ccNBPRga.s:341:32-bit
absolute addressing is not supported for x86-64
/var/folders/Rz/RzQTCSLsFPWQeOEO5EXsJE+++TI/-Tmp-//ccNBPRga.s:341:cannot
do signed 4 byte relocation

:-(.
