Fixes silent truncation of e.g.
cmp r0,-1
to
cmp r0,0xFF
in THUMB
Adds
add
-
sub
rewriting for ARM/THUMB e.g.
add -1
to
sub 1
Fixes ARM shifted immediate check causing e.g.
add r0,0x123
being encoded as
0xFFFFFFFF
Tidy up the error messages a bit by removing unnecessary zero padding and displaying OriginalImmediate instead of modified Immediate
Expand tests for immediates
