## Test binaries created with the following commands:
|
|
|
|
## $ cat call-dwarf5.c
|
|
## __attribute__((noinline, noreturn)) void foo() {
|
|
## asm volatile("" ::: "memory");
|
|
## __builtin_unreachable();
|
|
## }
|
|
## __attribute__((noinline)) void bar() {
|
|
## asm volatile("nop" :::);
|
|
## foo();
|
|
## }
|
|
|
|
## int main() { bar(); }
|
|
|
|
## $ clang -gdwarf-5 call-dwarf5.c -fomit-frame-pointer -c -Os -o call-dwarf5.o
|
|
## $ clang -gdwarf-5 call-dwarf5.o -o call-dwarf5
|
|
|
|
## 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.
