llvm-6502/test/MC/Mips/higher_highest.ll
Jack Carter fc54d9e47a Mips relocations R_MIPS_HIGHER and R_MIPS_HIGHEST.
These 2 relocations gain access to the 
highest and the second highest 16 bits
of a 64 bit object.

R_MIPS_HIGHER %higher(A+S)
The %higher(x) function is [ (((long long) x + 0x80008000LL) >> 32) & 0xffff ]. 

R_MIPS_HIGHEST %highest(A+S)
The %highest(x) function is [ (((long long) x + 0x800080008000LL) >> 48) & 0xffff ].
