remove-section-error.test

# RUN: yaml2obj %s -o %t
# RUN: not llvm-objcopy --remove-section __DATA,C %t /dev/null 2>&1 | FileCheck %s

# CHECK: symbol '_a' defined in section with index '2' cannot be removed because it is referenced by a relocation in section '__TEXT,__text'

## The binary used in this test was built as follows: 
## main.c: 
##   __attribute__((section("__DATA,C"))) int a = 2;
##   int f() { return a; }
## build command:
## clang -fno-exceptions -fno-unwind-tables -c main.c -o main.o
