[A bug?] Failed to use BuildMI to add R7 - R12 registers for tADDi8 and tPUSH of ARM
Hi all,
I’m trying to insert some add/sub and push/pop instructions in a MachineFunction pass for ARMv7-M. However, I encountered something weird.
For an add, when I use
BuildMI(….., TII->get(ARM::tADDi8), reg).addReg(reg).addReg(reg).addImm(imm).
if reg is R0 - R7, everything is fine: I would get something like
adds r1, 4
But if I use R8 - R12 as the reg in the BuildMI, I wouldn’t get
