Test binaries created with the following commands:
$ cat call.c
__attribute__((noinline, noreturn)) void foo() {
asm volatile("" ::: "memory");
__builtin_unreachable();
}
__attribute__((noinline)) void bar() {
asm volatile("nop" :::);
foo();
}
int main() { bar(); }
$ clang -g call.c -fomit-frame-pointer -c -Os -o call.o
$ clang -g call.o -o call
The test requires the return PC to match a relocation (in this case the
DW_AT_high_pc of main). Without this change the value would get relocated
twice.
