/* { dg-do compile { target *-*-darwin* } } */ /* Here we want to test if "foo" gets placed into a coalesced section (it should not). However, for i386, and PIC code we have a "get_pc thunk" that is (correctly) placed in a coalesced section when using an older linker - also unwind tables are emitted into coalesced. With modern linkers this is moot, since even weak symbols are emitted into the regular sections. To avoid the unwind tables -fno-asynchronous-unwind-tables. To ensure that we emit code for an older linker -mtarget-linker To avoid the get_pc thunk optimise at least O1. */ /* { dg-options "-fno-asynchronous-unwind-tables -O1 -mtarget-linker 85.2" } */ /* { dg-require-weak "" } */ /* { dg-final { scan-assembler-not "coalesced" } } */ extern void foo(void) __attribute__((weak_import)); void foo(void) { }
