From 41b5368f31f86a1c2be2bb16a1cf18d23f1223d4 Mon Sep 17 00:00:00 2001 From: Taras Kondratiuk Date: Fri, 8 Nov 2013 18:29:29 +0000 Subject: [PATCH] ARM: kprobes-test: Workaround GAS .align bug By default if no fill symbol is given to .align directive in a code section it fills gap with NOPs. If previous fragment is not instruction-aligned, additional pre-alignment is done by zero bytes before NOPs. These zero bytes are marked as data by special symbol $d in symbol table. Unfortunately GAS assumes that there is only code in the code section so it "puts back" code symbol $a at the end of this pre-alignment. So if there is some data after alignment it will be interpreted as code and will be swapped back to LE for BE8 system during a final linking. If explicit fill value is given to .align, the NOP-padding code is skipped and symbol table does not get messed-up. So the workaround for this issue: Use explicit fill value if data should be aligned in the code section.
