+ifdef MOZ_THUMB2 #{
+# The syscall number is passed through r7 in the linux ARM ABI, but r7
+# is also the THUMB frame pointer.  (Unfortunate, but ah well.)  gcc
+# complains if we store to r7, not unreasonably, but complains
+# inconsistently.  The generic syscall template pushes/stores to/pops
+# r7 with no complaint from gcc, but the sys_clone() function marks r7
+# as a clobbered register yet gcc error's.  The generated assembly for
+# sys_clone() looks OK, so we chalk this up to a gcc/gas quirk and
+# work around it by telling gcc that the THUMB frame pointer is a
+# vanilla callee-save register.
