2012-11-14PR14279: Work around this major miscompilation by treating move operations asRichard Smith
non-trivial if they would not call a move operation, even if they would in fact call a trivial copy operation. A proper fix is to follow, but this small directed fix is intended for porting to the 3.2 release branch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167920 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-14Remove debugging assert.David Blaikie
Found by Richard Smith in post-commit review of r167906. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167911 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-14Provide the correct mangling and linkage for certain unnamed nested classes.David Blaikie
This corrects the mangling and linkage of classes (& their member functions) in cases like this: struct foo { struct { void func() { ... } } x; }; we were accidentally giving this nested unnamed struct 'no' linkage where it should've had the linkage of the outer class. The mangling was incorrecty too, mangling as TU-wide unnamed type mangling of $_X rather than class-scoped mangling of UtX_. This also fixes -Wunused-member-function which would incorrectly diagnose 'func' as unused due to it having no linkage & thus appearing to be TU-local when in fact it might be correctly used in another TU. Similar mangling should be applied to function local classes in similar cases but I've deferred that for a subsequent patch. Review/discussion by Richard Smith, John McCall, & especially Eli Friedman. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167906 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-14Remove another questionable use of hasTrivial*. The relevant thing for thisRichard Smith
test was whether the /selected/ operator= was trivial, not whether the class had any trivial (or any non-trivial) operator=s. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167897 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-13[ms] Make mangleIntegerLiteral less aware of exact type of the literal.Nico Weber
Integer literal mangling does not actually depend on exact type of the literal. This will simplify calling mangleIntegerLiteral when literal type is not known, for example, when sizes or offsets are mangled as integer literals. Also, call mangleNumber instead of directly printing mangled values of 0/1, to avoid this knowledge from being in multiple places. Patch from Evgeny Eltsin! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167878 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-26When an externally-supplied record layout has a size that clearlyDouglas Gregor
doesn't include padding up to the alignment of the record, take this as a cue that the alignment of the record should (conservatively) be set to 1.
