/* ??? 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. */

/* Special handling here: Many machines do not use a frame pointer,
|
|
|
|
|
and track the CFA only through offsets from the stack pointer from
|
|
|
|
|
one frame to the next. In this case, the stack pointer is never
|
|
|
|
|
stored, so it has no saved address in the context. What we do
|
|
|
|
|
have is the CFA from the previous stack frame.
|
|
|
|
|
|
|
|
|
|
In very special situations (such as unwind info for signal return),
|
|
|
|
|
there may be location expressions that use the stack pointer as well.
|
|
|
|
|
|
2003-05-06 19:28:37 +02:00
|
|
|
|
Do this conditionally for one frame. This allows the unwind info
|
|
|
|
|
for one frame to save a copy of the stack pointer from the previous
|
|
|
|
|
frame, and be able to use much easier CFA mechanisms to do it.
|
|
|
|
|
Always zap the saved stack pointer value for the next frame; carrying
|
|
|
|
|
the value over from one frame to another doesn't make sense. */
