<pre>Try to compile the following with clang, targetting ARM:
asm (".align 4\n"
".globl co_switch_arm\n"
".globl _co_switch_arm\n"
"co_switch_arm:\n"
"_co_switch_arm:\n"
" stmia r1!, {r4, r5, r6, r7, r8, r9, r10, r11, sp, lr}\n"
" ldmia r0!, {r4, r5, r6, r7, r8, r9, r10, r11, sp, pc}\n" );
When going via assembler (i.e. -save-temps), it builds a working object file.
Direct emission results in an invalid binary, which crashes readelf from
binutils 2.23.2 or results in hangs in libbfd users.</pre>
