/* ??? For the public function interfaces, we tend to gcc_assert that the
column numbers are in range. For the dwarf2 unwind info this does happen,
although so far in a case that doesn't actually matter.
See PR49146, in which a call from x86_64 ms abi to x86_64 unix abi stores
the call-saved xmm registers and annotates them. We havn't bothered
providing support for the xmm registers for the x86_64 port primarily
because the 64-bit windows targets don't use dwarf2 unwind, using sjlj or
SEH instead. Adding the support for unix targets would generally be a
waste. However, some runtime libraries supplied with ICC do contain such
an unorthodox transition, as well as the unwind info to match. This loss
of register restoration doesn't matter in practice, because the exception
is caught in the native unix abi, where all of the xmm registers are
call clobbered.
Ideally, we'd record some bit to notice when we're failing to restore some
register recorded in the unwind info, but to do that we need annotation on
the unix->ms abi edge, so that we know when the register data may be
discarded. And since this edge is also within the ICC library, we're
unlikely to be able to get the new annotation.
Barring a magic solution to restore the ms abi defined 128-bit xmm registers
(as distictly opposed to the full runtime width) without causing extra
overhead for normal unix abis, the best solution seems to be to simply
ignore unwind data for unknown columns. */

TEMPBASE.

Output file name is randomly chosen.

output is written to the output file name. The file
will not be removed. If PEX_LAST and PEX_SUFFIX are
both set, TEMPBASE may not be NULL.
ERRNAME If not NULL, this is the name of a file to which
standard error is written. If NULL, standard error of
the program is standard error of the caller.
