Greg Clayton c4a99bc416 Patch from Kirk Beitz that removes an unneeded include of "sys/errno.h". 
llvm-svn: 124638
 2011-02-01 01:13:32 +00:00
Argyrios Kyrtzidis 0d349f9b8a When initializing struct members, the important thing is that the "initializing" expression is 
compatible, not having the same type.

Fix rdar://8183908 in which compatible vector types weren't initialized properly leading to a crash.

Rafael Espindola 08bccdad19 Don't tell the linker about available_externally definitions. If we do, it will 
complain about duplicated definitions.

 2011-02-01 00:41:51 +00:00
Rafael Espindola 9fa5a67d3d Set visibility for available_externally globals. This is important for two reasons: 
* llvm-link would complains about mismatched visibility
* If we produce a relocation with an available_externally, it is good to know that
it is hidden.

Daniel Dunbar a2867c7741 libclang: Don't allow RemoveFileOnSignal to be called via libclang, badness can 
ensue.

llvm-svn: 124613
 2011-01-31 22:00:44 +00:00
Daniel Dunbar e326f9bb3e Frontend: Add an explicit RemoveFileOnSignal flag argument, to control the 
automatic behavior (which is undesirable in a multithreaded context).

Argyrios Kyrtzidis dd88dbf9d2 Add -Wcustom-atomic-properties which warns if an atomic-by-default property has custom getter or setter. 
The rationale is that it is highly likely that the user's getter/setter isn't atomically implemented. Off by default.
Addresses rdar://8782645.

-Wcustom-atomic-properties and -Wimplicit-atomic-properties are under the -Watomic-properties group.

Douglas Gregor 058d3deab8 Implement reasonable conversion ranking for Objective-C pointer 
conversions (<rdar://problem/8592139>) for overload resolution. The
conversion ranking mirrors C++'s conversion ranking fairly closely,
except that we use a same pseudo-subtyping relationship employed by
Objective-C pointer assignment rather than simple checking
derived-to-base conversions. This change covers:

  - Conversions to pointers to a specific object type are better than
  conversions to 'id', 'Class', qualified 'id', or qualified 'Class'
  (note: GCC doesn't perform this ranking, but it matches C++'s rules
  for ranking conversions to void*).
  - Conversions to qualified 'id' or qualified 'Class' are better than
  conversions to 'id' or 'Class', respectively.
  - When two conversion sequences convert to the same type, rank the
  conversions based on the relationship between the types we're
  converting from. 
  - When two conversion sequences convert from the same non-id,
  non-Class type, rank the conversions based on the relationship of
  the types we're converting to. (note: GCC allows this ranking even
  when converting from 'id', which is extremeley dangerous).

Douglas Gregor 205d5e3a51 Implement the suggested resolution to core issue 547, extended to also 
allow ref-qualifiers on function types used as template type
arguments. GNU actually allows cv-qualifiers on function types in many
places where it shouldn't, so we currently categorize this as a GNU
extension.
