Big thanks, i've managed to find what's going on. The thing that dumbfolded me a couple of times was that the error was thrown in one of the MCAssembler methods, but never in applyFixup() itself.

Hi all, Can someone please explain me how to use REG_SEQUENCE in tablegen? The arch i'm writing backend for has 32-bit regs, and it has a couple of 64-bit load/store instructions which use two neighboring regs at once, which i'm trying to employ using virtual regs with subs. For example, it I want to move one 64-bit virtual reg to another, I'm trying to use the following pattern:

...MCExpr, it creates fixup, and I can see this fixup in debug. - Fixup is called fixup_Epiphany_PCREL24, and is defined in EpiphanyFixupKinds and EpiphanyAsmBackend, with FKF_IsPCRel flag. Can someone please tell me if I am missing something?
