| 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. |
