This can happen when a # difference expression refers to two symbols, at least one of which is # not defined at the point it is referenced. Then during *assembler* # relaxation when both symbols have become defined the difference may be folded # down to a fixup simply containing the absolute value. We want to ensure that # we don't force a relocation to be emitted for this absolute value even # when linker relaxation is enabled. The reason for this is that one instance # where this pattern appears in in the .eh_frame section (the CIE 'length' # field), and the .eh_frame section cannot be parsed by the linker unless the # fixup has been resolved to a concrete value instead of a relocation. .data lo: .word hi-lo .quad hi-lo # NORELAX-RELOC-NOT: R_RISCV_32 # NORELAX-RELOC-NOT: R_RISCV_64 # RELAX-RELOC-NOT: R_RISCV_32 # RELAX-RELOC-NOT: R_RISCV_64 hi:
