1# The pushl in CTOR initialization interferes with frame pointer elimination. 2# crtend*.o cannot be compiled without -fno-asynchronous-unwind-tables, 3# because then __FRAME_END__ might not be the last thing in .eh_frame 4# section. -fno-asynchronous-unwind-tables is off by default for i386 5# and is on by default for x86-64. We turn it off for both i386 and 6# x86-64. 7CRTSTUFF_T_CFLAGS += -fno-omit-frame-pointer -fno-asynchronous-unwind-tables 8
