[WinEH] Allocate the registration node before the catch objects

The CatchObjOffset is relative to the end of the EH registration node
for 32-bit x86 WinEH targets.  A special sentinel value, 0, is used to
indicate that no catch object should be initialized.

This means that a catch object allocated immediately before the
registration node would be assigned a CatchObjOffset of 0, leading the
runtime to believe that a catch object should not be initialized.

To handle this, allocate the registration node prior to any other frame
object.  This will ensure that catch objects will not be allocated
before the registration node.

This fixes PR26757.

behavior when we don't find one will have `"ps4-ld"` in it. We just need
a path separator to know that a path has been found.

The root cause of the flakiness of these tests is the same on Windows

to guarantee that a particular path is looked up first.
Driver::GetProgramPath checks some paths before deferring to PATH

[analyzer] Don't treat calls to system headers as escaping in CheckObjCDealloc.

This prevents false negatives when a -dealloc method, for example, removes itself as
as an observer with [[NSNotificationCenter defaultCenter] removeObserver:self]. It is
unlikely that passing 'self' to a system header method will release 'self''s instance
variables, so this is unlikely to produce false positives.

A challenge here is that while CheckObjCDealloc no longer treats these calls as
escaping, the rest of the analyzer still does. In particular, this means that loads
from the same instance variable before and after a call to a system header will
result in different symbols being loaded by the region store. To account for this,
the checker now treats different ivar symbols with the same instance and ivar decl as
the same for the purpose of release checking and more eagerly removes a release
requirement when an instance variable is assumed to be nil. This was not needed before
because when an ivar escaped its release requirement was always removed -- now the
requirement is not removed for calls to system headers.

analysis we *invalidate* the analysis even if there was *no*
modification made by the transform pass.

This means that currently we don't take advantage of LLE and LV sharing
the same analysis (LAA) and unfortunately we recompute LAA *and* SCEV
for LLE.

(There should be a way to work around this limitation in the case of
SCEV and LAA since both compute things on demand and internally cache
their result.  Thus we could pretend that transform passes preserve
these analyses and manually invalidate them upon actual modification.
On the other hand the new pass manager is supposed to solve so I am not
sure if this is worthwhile.)

8 years agoFix PR26585 by improving the promotion of DBG_VALUEs to DW_AT_locations.
Adrian Prantl [Mon, 29 Feb 2016 19:49:46 +0000 (19:49 +0000)]
Fix PR26585 by improving the promotion of DBG_VALUEs to DW_AT_locations.
When a variable is described by a single DBG_VALUE instruction we can
often use a more efficient inline DW_AT_location instead of using a
location list.

This commit makes the heuristic that decides when to apply this
optimization stricter by also verifying that the DBG_VALUE is live at the
entry of the function (instead of just checking that it is valid until
the end of the function).
