The difference in the assembler between the 4.9.2 compiler (good) and the trunk compiler (bad, revision 217599) is: $ diff -pu good-49.s bad-trunk.s --- good-49.s 2014-11-15 16:33:50.000000000 +0100 +++ bad-trunk.s 2014-11-15 16:33:30.000000000 +0100 @@ -3,6 +3,15 @@ _foo: pushl %ebp movl %esp, %ebp + call ___x86.get_pc_thunk.ax +L1$pb: + nop popl %ebp ret + .section __TEXT,__textcoal_nt,coalesced,pure_instructions + .weak_definition ___x86.get_pc_thunk.ax + .private_extern ___x86.get_pc_thunk.ax +___x86.get_pc_thunk.ax: + movl (%esp), %eax + ret .subsections_via_symbols The presence of the line with "coalesced" makes the test fail.
