This is a question of the debugging setup code not

getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

Eliminate the remaining uses of getTypeSize. This
...
should only effect x86 when using long double. Now
12/16 bytes are output for long double globals (the
exact amount depends on the alignment). This brings
globals in line with the rest of LLVM: the space
reserved for an object is now always the ABI size.
One tricky point is that only 10 bytes should be
output for long double if it is a field in a packed
struct, which is the reason for the additional
argument to EmitGlobalConstant.

...
.set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
add r1, pc, #PCRELV0
This is not legal since add r1, pc, #c requires the constant be a multiple of 4.
Do the following instead:
.set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
mov r1, #PCRELV0
add r1, pc
- In thumb mode, it's not possible to use .set generate a pc relative stub
address. The stub is ARM code which is in a different section from the thumb
code. Load the value from a constpool instead.
