<pre>Assembling the following source:
.text
.thumb
subs r0, #(.-.+1)
with "clang -fintegrated-as -target armv7-none-linux-androideabi16 -c x.s"
produces, for example,
00000000 <.text>:
0: 38cb subs r0, #203 ; 0xcb
where the immediate value varies with each run.
This seems to affect any expression with addresses, e.g., (.-.), (.-.L0) etc.
The +1 is there just for non-zero expected output.
clang --version:
clang version 6.0.0 (tags/RELEASE_600/final)</pre>
