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

It's on by default, but can be turned off with a flag if you think you know what you're doing.
