similar to: R-loadable dll with minGW-compiled linked library

Hi I am new to Cygwin and Linux. I installed R under Cygwin as part of the setup I chose "All" during installation, for all packages. So I have the FULL installlation of cygwin up and running, including gfortran. *Under Cygwin, how do I check and configure the path to the various libraries?* I am trying below command and it says, cannot find "lgfortran" But I have installed

llvm (and clang) do not include binutils. You're seeing clang invoking the gcc shell to assemble the .s file that clang generated, then again to link the object file into an executable.

Hi everyone, I'm very new to the world of compilation and I've got to spend some time time on LLVM. As I have to produce a cross compiler for a completely new target and I don't want to cross-build the binutils, I choose Clang as a replacement frontend for llvm instead of llvm-gcc. But first, I just would like to compile something on my Linux platform in order to test the software,

'collect2.exe' is an internal version of 'ld' called by GCC The GCC command line is :- g++ -I/usr/build/llvm-2/tools/llc -I/usr/src/llvm/tools/llc -I/usr/build/llvm-2/ include -I/usr/src/llvm/include -I/usr/build/llvm-2/include -I/usr/src/llvm/incl ude -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -Wall -W -Wwrite-strings -Wno-unused -g -D_DEBUG -v -o /usr/build/llvm-2/Debug/bin/llc.exe

Thanks for your really fast answer. I understood that, but this means that the llvm+Clang suite is not able to create a machine binary file without any intervention of GCC ? I thought it could. This means too that I must port GCC+Binutils in order to have a LLVM port for my architecture ? That sound like a huge work, I've chosen LLVM at the beginnig because I thought it could avoid me

I am currectly experimenting with -Xclang option.. I have a simple pass (to just print function names). I ran: clang -Xclang -load -Xclang LLVMHello.so t.c but nothing was printed, no output from the pass. when I run: opt -load LLVMHello.so -hello t.ll I get the output from pass (i.e. list of function names) Part of the source ode of the Hello pass: struct Hello : public FunctionPass {

Hello, I have an analysis pass and a target machine class, both in different dynamically loadable libraries (plugins). There is no problem to use the analysis pass (opt -load=libanalysis.dylib -barpass foo.bc), but is it possible to get data from the analysis pass (by getAnalysis) while using the backend? AFAIK it is only allowed to have one plugin argument for llc (like: llc

Hi, is there a problem with loadable backends and some analysis passes? An example: If I put the C backend in my project directory, compile a library form the code, and try to load it into lli I get the following message: ------------------------------------------------------- lli -load /path/CBackend.dylib Error opening '/path/CBackend.dylib': dlopen(/path/CBackend.dylib, 1):

Hello all, Is it well known that building LLVM with --enable-optimized causes RegisterPass calls to be removed from dynamically loadable libraries (i.e., those built with LOADABLE_MODULE=1)? For example, here's what happens to the Hello pass (ToT on Darwin, both with and without --enable-optimized): $ pwd /Users/ransford/llvm/lib/Transforms/Hello $ nm -j Release+Asserts/Hello.o | c++filt -p

Interesting. Is the same assert triggered when you use RegisterPass to register the pass? Is getAnalysisUsage()

Dear LLVMers, I have a class X that represents a set of Value* in a specific way. That class is stored in two files: X.cpp and X.h The class X works perfectly in a pass that I already have. However, I need to use that class in some other passes, but I don't want to have a copy of X.cpp and X.h in every pass folder. I've tried to do the following: - put X.h in the folder

I want to write a C function that should return an object of unknown structure at the time of the invocation. In particular, I'd like to 1- return a string of unknown length 2- a vector or a matrix of unknown dims and of unknown element type 3- a data frame Is any of that possible? Are there examples? Which R functions should I call to create such objects? Any help would be appreciated.

Context: https://bugs.llvm.org/show_bug.cgi?id=39862 I'm trying to enable stack traces in an OS kernel. To do that the kernel needs access to its own debug info. I have this in my linker script: .debug_info : { __debug_info_start = .; KEEP(*(.debug_info)) __debug_info_end = .; } .debug_abbrev : { __debug_abbrev_start = .;
