2009-04-01x86-32 Darwin ABI: Handle small structures correctly.Daniel Dunbar
- Small structures are returned in a register if: 1. They fit nicely in a register. 2. All fields fit nicely in a register. (more or less) - We now pass the first 5000 ABITests if unions are disabled. - <rdar://problem/6497882> [irgen] x86-32 ABI compatibility with small structs git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68197 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-01x86-32 Darwin ABI: Single element arrays can be part of "singleDaniel Dunbar
element structures", which have different ABI rules. - Current return-arguments-32 status is: 1 out of 1000 failures (-7) - Also, vectors inside "single element structs" require special handling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68196 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-01Fix: <rdar://problem/6740387>. Sending nil to an object that returns a structTed Kremenek
should only be an error if that value is consumed. This fix was largely accomplished by moving 'isConsumedExpr' back to ParentMap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68195 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-01remove ASTContext::buildObjCInterfaceType, which breaks canonical Chris Lattner
types. It is no longer needed now that the code generator re-lays-out interfaces if they are defines after being laid out from a forward decl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68194 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-01- Changed PathDiagnosticPiece::getLocation() to return a PathDiagnosticLocationTed Kremenek
instead of a FullSourceLoc. This resulted in a bunch of small edits in various clients. - Updated BugReporter to include an alternate PathDiagnostic generation algorithm for PathDiagnosticClients desiring more control-flow pieces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68193 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-01Pull clang-cc code for generating PTH files based on the input type.Daniel Dunbar
- <rdar://problem/6741594> [pth] don't abuse -x to drive pth generation - Simpler, and fixes PR3915. Cleanup test cases for PTH: - Update to use -emit-pth - Removed PTH test of carbon.c and cocoa.mm; these didn't actually verify anything, and since PTH is token based the extra coverage (over cocoa.m) isn't particularly helpful. - Split PTH tests in cocoa.m to cocoa-pth.m, solely to increase available parallelism when running tests. Ted, could you update the PTH test cases (include-pth.c and cocoa-pth.m) to have some sort of positive check that the PTH is getting used? "# of PTH cache hits" or "tokens read from PTH cache" statistics would work great. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68189 91177308-0d34-0410-b5e6-96231b3b80d8
