#2231: arm cpu.c selects non-thumb code for Thumb only build
---------------------------+-----------------------------
 Reporter:  joel.sherrill  |      Owner:  sebastian.huber
     Type:  defect         |     Status:  new
 Priority:  normal         |  Milestone:  4.11
Component:  General        |    Version:  4.11
 Severity:  normal         |   Keywords:
---------------------------+-----------------------------
 Reported initially as gcc PR64542
 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64542) but rather clearly a
 problem in the selection of the inline assembly. The GCC PR has an
 attachment which is after the incorrect inline asm is selected.

 arm-rtems4.11-gcc -mthumb -march=armv6-m -c -O0 /tmp/arm-thumb-pr64542.c

 It looks like the wrong code in arm_interrupt_disable (and likely enable)
 is selected.

 RTEMS was configured as:

 /users/joel/test-gcc/rtems/configure --target=arm-rtems4.11 --enable-
 multilib --enable-ada --enable-posix --enable-networking --enable-
 maintainer-mode --disable-tests --prefix=/users/joel/test-
 gcc/install-4.9-branch
