## Tests that lld-macho can handle the case where personality symbols with the same name
## are both from a dylib and locally defined in an object file.
# REQUIRES: x86
# RUN: rm -rf %t; split-file %s %t
# RUN: llvm-mc -filetype=obj -triple=x86_64-apple-darwin19.0.0 %t/user_2.s -o %t/user_2.o

# RUN: yaml2obj %t/combined.yaml > %t/combined.o
## Pre-condition: check that ___gxx_personality_v0 really is locally defined in combined.o before we proceed.
# RUN: llvm-nm %t/combined.o | grep '___gxx_personality_v0' | FileCheck %s --check-prefix=PRECHECK
# PRECHECK: {{.*}} t ___gxx_personality_v0
# PRECHECK-NOT: {{.*}} U ___gxx_personality_v0
# PRECHECK-NOT: {{.*}} T ___gxx_personality_v0
## check that we can link with 4 personalities without crashing:
## ___gxx_personality_v0 (libc++.tbd), ___gxx_personality_v0(local), _personality_1, and _personality_2
# RUN: %lld -lSystem -lc++ %t/user_2.o %t/combined.o -o %t/a.out
