/* .eh_frame addresses should be the same width as a C pointer.
Most MIPS ABIs support only one pointer size, so the assembler
will usually know exactly how big an .eh_frame address is.
Unfortunately, this is not true of the 64-bit EABI. The ABI was
originally defined to use 64-bit pointers (i.e. it is LP64), and
this is still the default mode. However, we also support an n32-like
ILP32 mode, which is selected by -mlong32. The problem is that the
assembler has traditionally not had an -mlong option, so it has
traditionally not known whether we're using the ILP32 or LP64 form.
As it happens, gas versions up to and including 2.19 use _32-bit_
addresses for EABI64 .cfi_* directives. This is wrong for the
default LP64 mode, so we can't use the directives by default.
Moreover, since gas's current behavior is at odds with gcc's
default behavior, it seems unwise to rely on future versions
of gas behaving the same way. We therefore avoid using .cfi
directives for -mlong32 as well. */
