<pre>I cannot reproduce this with llvm trunk r242481. When I compile with clang
-target armv7a-- ("-arch armv7-a" doesn't seem to exist) I get the following:
foo_l: @ @foo_l
.fnstart
@ BB#0: @ %entry
push {r7, lr}
movw r1, :lower16:buf
mov r0, #0
movt r1, :upper16:buf
ldr sp, [r1, #8]
ldr r0, [r1, #4]
ldr r7, [r1]
bx r0
which looks correct. In any case I would also advise against using
__builtin_setjmp/__builtin_longjmp, they are not documented in the gcc or clang
manuals and are intended to implement compiler runtimes.</pre>
