2012-10-28Revert functional part of r166896 and just suppress ↵Richard Smith
-Wunneeded-internal-declaration for reference types for now. This needs more work; the cases we currently miss are a bit random. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166899 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-28When determining whether to try evaluating the initializer of a variable, checkRichard Smith
whether the initializer is value-dependent rather than whether we are in a dependent context. This allows us to detect some errors sooner, and fixes a crash-on-invalid if a dependent type leaks out to a non-dependent context in error recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166898 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-28In -Wunneeded-internal-declaration, suppress the warning for variables whichRichard Smith
might have been used in constant expressions, rather than suppressing it for variables which are const. The important thing here is that such variables can have their values used without actually being marked as 'used'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166896 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. This is similar to other the other cues we use to determine that the record has a lower alignment, e.g., that the externally-supplied layout places fields at lower offsets than we would.

2012-10-26This patch addresses a 64-bit PowerPC ELF ABI compatibility issue withBill Schmidt
varargs parameter passing. A strict reading of the ABI indicates that any argument with alignment greater than 8 may require skipping doublewords in the parameter save area to align the argument, and hence require skipping GPRs. In practice, this is not done by GCC. The alignment restriction is used for internal alignment of a structure, but a structure with 16-byte alignment, for example, is not itself 16-byte aligned in the parameter save area. Although this is messy, it has become the de facto standard used in building existing libraries. My initial varargs support followed the ABI language, but not the de facto standard. Running the GCC compatibility test suite exposed this issue, and indeed showed that LLVM didn't pass parameters self-consistently with my original logic. Removing the additional alignment logic allows the affected tests to now pass. I modified the ppc64-varargs-struct.c test case to remove the existing test for generation of alignment code, which is no longer appropriate. Built and tested on powerpc64-unknown-linux-gnu with no new regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166805 91177308-0d34-0410-b5e6-96231b3b80d8
