hi, I'm really new to llvm. I've successfully bootstrapped llvm-14 on my system and am able to successfully compile c code to llvm. the problem is now that gccld is complaining that it can't find the libraries, like "c" or "crtend". [1] all is fine, if I just use intrinsified functions like printf and friends, but I want to use the clock_gettime function and

Might anyone have a FreeBSD binary or suggested modifications to the source to compile one? Thanks, Sean

When I compiled a linux kernel, gccas was used to compile assembly code. But gccas cannot recognize the line comment character "#" of gnu assembler, and abort the compile with reporting a error "syntax error, unexpected $undefined". I watch llvm/tools/gccas, but donot known how to add this function in it. Would you give me some suggestions? Thanks.

Hi, I would like to use LLVM-GCC to compare its performance with other compilers. Something like testsuite "Computing very large Fibonacci numbers" at http://article.gmane.org/gmane.comp.lang.c%2B%2B.perfometer/37. My environment: ----------------- Windows 2000 Cygwin $ uname -srom CYGWIN_NT-5.0 1.5.11(0.116/4/2) i686 Cygwin ----------------- What do I have to download from

Hi, I'm able to build the llvm tools on the MinGW platform: burg, fpcmp, tblgen, llvm-as, llvm-dis, opt, gccas, llc, llvm-link, lli, gccld, llvm-stub, analyze and extract. I wonder if these tools are sufficient to start build the cfrontend?

Your output looks like gccas

Hi, I installed the cfrontend 1.5 and LLVM 1.5 from source in cygwin successfully using GCC3.4.3 and binutils2.15 (as in makefiles do not complain errors except some warnings). However when I do this, there are some errors like, *************************************************************** u0201201 at 9nnvf2ay /home/cfrontend/install/lib $ llvm-ranlib libiberty.a llvm-ranlib: Error opening

Sorry to disturb you all, but I simply cannot get the linearscan allocator to work. I have upgraded llvm to mainline cvs. Everything works until I get to llc -regalloc=linearscan or lli -regalloc=linearscan. I have installed it on redhat 9 and on Fedora Core distributions (I even took it as far as to format a new partition and install Fedora core all over). I have submitted the bytecode that

I'm another new person to LLVM. I can't successfully compile and execute a simple C++ program. The compiler seems to work, as it produces a.out and a.out.bc files, but I get a whole bunch of warnings: WARNING: Found global types that are not compatible: "struct.std::messages<wchar_t>"* %_ZN9__gnu_cxx10messages_cE [16 x sbyte]*

Hi John, I have attached my Makefile.config. I noticed that I did'nt have SRC_ROOT and OBJ_ROOT variables defined as such in my environment. But I noticed that this is defined in the Makefile.config by default to the same values. All the same, I tried defining both these variables in my .cshrc, but I still get the same error. The main directory for me is /home/llvm, and I have

I know that Al Stone has compiled llvm-gcc4 successfully and I can report the same. The problem I consistently run into is that llvm-gcc ends up producing native format output; it does not produce bytecode, nor does it invoke gccas or gccld. I'm using the latest svn, and my configure args are: --prefix=/work/scottm/llvm-cfrontend/obj/../i686-pc-linux-gnu \

Thank you, Reid, I tried llvm-gcc -lcrtend ary3.c -o ary3, but I get gccld: warning: Cannot find library 'crtend' gccld: warning: Cannot find library 'c' I have the libraries in my llvm directory: llvm/runtime/GCCLibraries/crtend Well, how do I link this to the LLVM runtime stuff? Before building from the source, I had copied all the .h from my old gcc 4.0 to
