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

per review discussion in r170365 This does limit these typedefs to being sequences, but no current usage requires them to be contiguous (we could expand this to a more general iterator pair range concept at some point). Also, it'd be nice if SmallVector were constructible directly from an ArrayRef but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the inverse conversion.

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

2012-12-09Cleanup and fix an assert that was mis-firing.Chandler Carruth
Note that there is no test suite update. This was found by a couple of tests failing when the test suite was run on a powerpc64 host (thanks Roman!). The tests don't specify a triple, which might seem surprising for a codegen test. But in fact, these tests don't even inspect their output. Not at all. I could add a bunch of triples to these tests so that we'd get the test coverage for normal builds, but really someone needs to go through and add actual *tests* to these tests. =[ The ones in question are: test/CodeGen/bitfield-init.c test/CodeGen/union.c git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169694 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-09Fix the bitfield record layout in codegen for big endian targets.Chandler Carruth
This was an egregious bug due to the several iterations of refactorings that took place. Size no longer meant what it original did by the time I finished, but this line of code never got updated. Unfortunately we had essentially zero tests for this in the regression test suite. =[ I've added a PPC64 run over the bitfield test case I've been primarily using. I'm still looking at adding more tests and making sure this is the *correct* bitfield access code on PPC64 linux, but it looks pretty close to me, and it is *worlds* better than before this patch as it no longer asserts! =] More commits to follow with at least additional tests and maybe more fixes.

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
