similar to: [LLVMdev] Replace gcc with llvm-gcc

Just set llvm-ld as the default ld . Such as LD = llvm-ld in makefile, if it's not working, then there is no solution 2009/9/15, zhunan <zhunansjtu at gmail.com>: > I truly get the bytecode file for each souce file,but can I use > llvm-link to link them into a whole-program one automatically through > some scripts? > > >> >> Message: 27 >> Date: Tue, 15

Hi,all Recently I met a question when I want to replace gcc with llvm-gcc through configure script(command). For simply,described like that I typed as following 1.zhunan at sjtu:~/workplace/$ ./configure CC=llvm-gcc CFLAGS="-S -emit-llvm" configure will failed when it checks whether C compiler is working 2.zhunan at sjtu:~/workplace/$ ./configure CC=llvm-gcc CFLAGS="-c

For such Makefiles, the above will not work because llvm-gcc runs ld. What you need is a linker that can link LLVM bitcode files together. If that is the case,

Thank you for the reply,but I meant that when we building,we can not use the native tools such ar and as to process the llvm files,we must have the ability to call llvm-ar and llvm-as instead of the native ones. 在 2009-10-17六的 19:35 -0700，Nick Lewycky写道： > zhunan wrote: > > Hi, > > > > I don't think just use gold-plugin even modified is enough for the task > > of

Yes,but when I just simply replace lto_codegen_compile(cg, ...) with lto_codegen_write_merged_modules(cg, "/path/to/output.bc") in the gold-plugin.cpp to see if it will generate a correct bc file,the llvm-gcc/llvm-g++ will call the native ld in the linking step,which causes the failture because of that ld can not recognize an object file which contains LLVM's IL. I understand the

Could be. Are you comfortable using gdb? Last time I looked it was working for me.

We can use the native tools if they understand llvm IL :-) That is what the plugin does. With it installed you can run

Hi,all Where may I find the binary encode of llvm's ISA? I would like to load the instructions from llvm bitcode file and translate it to another kind of ISA dinamically,but I searched all docs in llvm.org,nothing has been found ,can anyone help me? zhunan 2009.7.1

Yes,but ubuntu's directory structure is not exactly the same as the classic linux distribute, I put libLLVMgold.so in /usr/lib/gcc/i486-linux-gnu/4.2.4 where cc1 is also in. Strange situation,is it a bug for llvm-gcc???? 在 2009-09-18五的 12:58 +0300，Török Edwin写道： > On 2009-09-18 03:06, Nan Zhu wrote: > > OMG,that's just my situation... > > > > I can link with

Hi,all Recently,I write some code to implement the following funtions: I make use the codes of "llvm-dis" to disassemble the bitcode file and do some change on it,after that ,"my llvm-as" assembles the changed file to generate a bitcode file. But I got a "corrupted double-linked list" error when "my llvm-as" works,however,when I do nothing on the

Dear R listers, I posted this problem several days ago but it seems nobody answered. I use nlm to optimize a given function ,but it always generates the following warnings " Error in nlm(foo, theta.start) : non-finite value supplied by 'nlm' " I don't know why ,can anybody give me some hints ?? thanks in advance. regards .

Sorry for forgetting to reply all... It works! Thank you very much! But I also wonder how do you know this function will work while there are no documents noticing that. I try learning LLVM by reading its code, but soon feel lost in so many functions. Just like I have many tools, but don't know which to use and what difference it could make. Is there some better ways to learn LLVM? On Wed,

Try this: $ llvm-gcc -### -x c /dev/null Then look for a line
