2013-01-14This patch addresses varargs processing for small complex types underBill Schmidt
the 64-bit PowerPC ELF ABI. The ABI requires that the real and imaginary parts of a complex argument each occupy their own doubleword. Arguments smaller than 8 bytes are right-adjusted within the doubleword. Clang expects EmitVAARG() to return a pointer to a structure in which the real and imaginary parts are packed adjacently in memory. To accomplish this, we generate code to load the code appropriately from the varargs location and pack the values into a temporary variable in the form Clang expects, returning a pointer to that structure. The test case demonstrates correct code generation for all "small" complex types on PPC64: int, short, char, and float. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172438 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-21Don't eagerly emit a global static merged with a local extern.Rafael Espindola
When we are visiting the extern declaration of 'i' in static int i = 99; int foo() { extern int i; return i; } We should not try to handle it as if it was an function static. That is, we must consider the written storage class. Fixing this then exposes that the assert in EmitGlobalVarDeclLValue and the if leading to its call are not completely accurate. They were passing before because the second decl was marked as having external storage. I changed them to check the linkage, which I find easier to understand. Last but not least, there is something strange going on with cuda and opencl. My guess is that the linkage computation for these languages needs to be audited, but I didn't want to change that in this patch so I just updated the storage classes to keep the current behavior. Thanks to Reed Kotler for reporting this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170827 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-18CodeGen: Expand creal and cimag into complex field loadsMeador Inge
PR 14529 was opened because neither Clang or LLVM was expanding calls to creal* or cimag* into instructions that just load the respective complex field. After some discussion, it was not considered realistic to do this in LLVM because of the platform specific way complex types are expanded. Thus a way to solve this in Clang was pursued. GCC does a similar expansion. This patch adds the feature to Clang by making the creal* and cimag* functions library builtins and modifying the builtin code generator to look for the new builtin types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170455 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-12Rewrite calls to bitcast unprototyped functions when emitting a definition.John McCall
My variadics patch, r169588, changed these calls to typically be bitcasts rather than calls to a supposedly variadic function. This totally subverted a hack where we intentionally dropped excess arguments from such calls in order to appease the inliner and a "warning" from the optimizer. This patch extends the hack to also work with bitcasts, as well as teaching it to rewrite invokes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170034 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-07Fix the required args count for variadic blocks.John McCall
We were emitting calls to blocks as if all arguments were required --- i.e. with signature (A,B,C,D,...) rather than (A,B,...). This patch fixes that and accounts for the implicit block-context argument as a required argument. In addition, this patch changes the function type under which we call unprototyped functions on platforms like x86-64 that guarantee compatibility of variadic functions with unprototyped function types; previously we would always call such functions under the LLVM type T (...)*, but now we will call them under the type T (A,B,C,D,...)*. This last change should have no material effect except for making the type conventions more explicit; it was a side-effect of the most convenient implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169588 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-06Rework the bitfield access IR generation to address PR13619 andChandler Carruth
generally support the C++11 memory model requirements for bitfield accesses by relying more heavily on LLVM's memory model. The primary change this introduces is to move from a manually aligned and strided access pattern across the bits of the bitfield to a much simpler lump access of all bits in the bitfield followed by math to extract the bits relevant for the particular field. This simplifies the code significantly, but relies on LLVM to intelligently lowering these integers. I have tested LLVM's lowering both synthetically and in benchmarks. The lowering appears to be functional, and there are no really significant performance regressions. Different code patterns accessing bitfields will vary in how this impacts them. The only real regressions I'm seeing are a few patterns where the LLVM code generation for loads that feed directly into a mask operation don't take advantage of the x86 ability to do a smaller load and a cheap zero-extension. This doesn't regress any benchmark in the nightly test suite on my box past the noise threshold, but my box is quite noisy. I'll be watching the LNT numbers, and will look into further improvements to the LLVM lowering as needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169489 91177308-0d34-0410-b5e6-96231b3b80d8
