For instructions with 'pc' as the 'Rn' register in addressing mode, the offset
is always > 0:
The following source code:
strcc r7, [pc], #-1931
strcc r7, [pc], #1931
strcc r7, [r4], #-1931
strcc r7, [r4], #1931
is disasembled as follow:
84: 340f778b strcc r7, [pc], #1931 ; 8c <test+0x8>
88: 348f778b strcc r7, [pc], #1931 ; 90 <test+0xc>
8c: 3404778b strcc r7, [r4], #-1931
90: 3484778b strcc r7, [r4], #1931
There is an error in line 84.
Note that if Rn is not 'pc', the '-' is printed correctly.
