similar to: [LLVMdev] LLVM+Clang 3.2rc2 MinGW binaries' libstdc++ requirement

I attempted to run the 3.2rc2 experimental LLVM+Clang package for Mingw32/x86 [1], and ran into difficulty finding a suitable version of MinGW to run it with. Part of the problem is that Windows G++ changed its C++ ABI in 4.7 [2]. Through experimentation, I've determined that the LLVM binaries do not run using the libraries shipped with TDM-GCC 4.5 because there is a missing symbol.

I rewrote scatter.smooth to handle missing values, but I have a question about a move I had to make. Here's the code: Mscatter.smooth<-function (x, y, span = 2/3, degree = 1, family = c("symmetric", "gaussian"), xlab = deparse(substitute(x)), ylab = deparse(substitute(y)), ylim = range(y, prediction$y), evaluation = 50, ...) { if (inherits(x,

Hi, [This is a follow-up to the "New version of Rtools for Windows" thread in January, but I just subscribed and don't know how to reply to an old thread -- my apologies.] I was able to use the nuwen distro to build a gcc 4.9.2 toolchain and use it to build the latest R-patched with it. Below are some notes about what I did; I hope they will be useful for keeping Rtools

I am experimenting with rSymPy, and it seems to work nice. However, I dislike the need to wrap all sympy expressions within quotes, it leads to ugly calls like library(rSymPy) Var("x,y,z") sympy("(x+y)**2") and so on. Inspired by the function cq from mvbutiles package: library(mvbutils) > cq function (...) { as.character(sapply(as.list(match.call(expand.dots =

Hello Aaron, Anton, LLVM-dev, While working on http://llvm.org/PR13676#c6 I found out that whenever I compile code with class methods returning structures it get generated incompatible with MSVC. Looking at lib/Target/X86/X86CallingConv.td, I found out that CC_X86_32_ThisCall maps SRet to EAX but in fact it should push the address of the return temp on stack. The following patch fixes the issue

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 There doesn't appear to be a calling convention matching "thiscall"... on gcc targets, the standard calling convention is fine (just pass "this" as the first parameter), but with MSVC this won't work because it passes "this" in %ECX. Is there a workaround for this? Or how hard would it be to add a separate

Hello all, I wanna build a static linked executable using llvm. But I failed. My question is Can we use -static using llvm? Thanks for any response. Below is details ======== First I use $ clang++ test.cc `llvm-config --cxxflags --ldflags --libs` I works as usual. But if I use $ clang++ test.cc `llvm-config --cxxflags --ldflags --libs` -static It yells lots of undefined reference, like

Hi, After a discussion with David, Id like to propose a rework of the Windows target triples. The current set of Windows triples are somewhat less uniform than their Linux counterparts. With multiple ABIs and environments on Windows, they are also slightly awkward. Obviously, certain ones might be nice to keep around for compatibility (e.g. the mingw triple). Just to ensure that everyone has

Maybe combining the patches would be the best? It is funny, I had never tried check-all on mingw. I just did and found some codegen errors, mostly when we look for
