- Fix codegen for pc relative constant (e.g. JT) in thumb mode:
.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.
- Some asm printing clean up.
