+#
+# But where this section will reside finally in vmlinx is undetermined at

+#
+# The trick is to change the call offset referring the start of a section to
+# referring a function symbol in this section. During the link step, 'ld' will
+# compute the final address according to the information we record.
#
-# The trick is to find a way to record the beginning of the section.
-# The way we do this is to look at the first function in the section
-# which will also be the location of that section after final link.

#
# .section ".sched.text", "ax"

+# ret
+# func3:
+# [...]
+# call mcount (offset: 0x30)
# [...]
#
# Both relocation offsets for the mcounts in the above example will be

+# offset from .sched.text. If we choose global symbol func2 as a reference and
+# make another file called tmp.s with the new offsets:
#
# .section __mcount_loc
-# .quad my_func + 0x5
-# .quad my_func + 0x1b
+# .quad func2 - 0x10
+# .quad func2 + 0x10
#
-# We can then compile this tmp.s into tmp.o, and link it to the original
+# We can then compile this tmp.s into tmp.o, and link it back to the original
# object.
#
-# But this gets hard if my_func is not globl (a static function).
-# In such a case we have:
+# In our algorithm, we will choose the first global function we meet in this
+# section as the reference. But this gets hard if there is no global functions
+# in this section. In such a case we have to select a local one. E.g. func1:
#
# .section ".sched.text", "ax"
-# my_func:
+# func1:
# [...]
-# call mcount (offset: 0x5)
+# call mcount (offset: 0x10)

+# func2:
# [...]
-# call mcount (offset: 0x1b)
+# call mcount (offset: 0x20)
# [...]
+# .section "other.section"
#
# If we make the tmp.s the same as above, when we link together with
