Hi Eli,

The pair of instructions constraint is that the instruction (or instructions) with the LO12 relocation label points to a valid HI20 relocation which  in turn points to the symbol:

At label: R_RISCV_PCREL_HI20 relocation entry ⟶ symbol
R_RISCV_PCREL_LO12_I relocation entry ⟶ label

See https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md#relocations

Let us know if you have a suggestion on how to do this matching some other way.
