## 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. #RUN: dsymutil -oso-prepend-path %p/../Inputs -y %s -o %t.dSYM #RUN: llvm-dwarfdump %t.dSYM | FileCheck %s -implicit-check-not=DW_AT_call_return_pc #RUN: dsymutil --linker parallel -oso-prepend-path %p/../Inputs -y %s -o %t.dSYM #RUN: llvm-dwarfdump %t.dSYM | FileCheck %s -implicit-check-not=DW_AT_call_return_pc #CHECK: DW_AT_call_return_pc (0x0000000100000f72) #CHECK: DW_AT_call_return_pc (0x0000000100000f78) --- triple: 'x86_64-apple-darwin' objects: - filename: 'call-dwarf5.o' timestamp: 1675373912 symbols: - { sym: _foo, objAddr: 0x0, binAddr: 0x100000F69, size: 0x2 } - { sym: _bar, objAddr: 0x2, binAddr: 0x100000F6B, size: 0x7 } - { sym: _main, objAddr: 0x9, binAddr: 0x100000F72, size: 0x6 } ...
