+Subject: [PATCH] arm: Fix SIGBUS on ARM when compiled with binutils 2.29
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In binutils 2.29, the behavior of the ADR instruction changed so that 1 is
+added to the address of a Thumb function (previously nothing was added). This
+allows the loaded address to be passed to a BLX instruction and the correct
+mode change will occur.
+
+See: https://sourceware.org/bugzilla/show_bug.cgi?id=21458
+
+By using adr with a label that isn't annotated as a thumb function,
+we avoid the new behaviour in binutils 2.29 and get the same behaviour
+as in prior releases, and as in other assemblers (ms armasm.exe,
+clang's built in assembler) - an idea that Janne Grunau came up with.
