 Common register allocation / spilling problem:

-       str lr, [sp, #+52]
-       ldr lr, [r1, #+32]
-       sxth r3, r3

+        ldr r4, [sp, #+52]
+        mla r4, r3, lr, r4
 
 can be:
 
-       mul lr, r4, lr
+        mul lr, r4, lr
         mov r4, lr
-       str lr, [sp, #+52]

+        ldr lr, [r1, #+32]
+        sxth r3, r3
+        mla r4, r3, lr, r4
 
 and then "merge" mul and mov:
 
-       mul r4, r4, lr
-       str lr, [sp, #+52]
-       ldr lr, [r1, #+32]
-       sxth r3, r3

+        str lr, [sp, #+52]
+        ldr lr, [r1, #+32]
+        sxth r3, r3
+        mla r4, r3, lr, r4
 
 It also increase the likelyhood the store may become dead.
