In addition bootstrap appears to break in dwarf2asm.c with a similar looking
backtrace ... I haven't dug in further but it's definitely higher than P3 as it
breaks bootstrap for a primary target.

I am not sure that is a LRA merge problem. LRA merge should not affect ARM
because old reload should work for ARM. There is a very small change for arm.c
because I added a new argument for final.c::alter_subreg. There is few changes
in IRA too but again I don't think it affect ARM.
Could you provide a preprocessed file because I can not reproduce the problem
by myself. Thanks.
