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 -emit-llvm" configure will failed when it checks the default output filena...

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 Sep 2009 03:16:10 +0200 >> From: ?...

...Linux. On Mac OS X, I think the linker with Xcode can link bitcode files together, but I'm not sure. Please note that I haven't tried this myself yet; it's one of the things I will try the next time I need to create a single bitcode file for an executable. -- John T. > 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...

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

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 building a whole-program bc file. > > > > When we want to build a whole-program bc file by a general solution(I > > meant that we can use such a meth...

...s the only available tool,so I think gold-plugin is not very useful to archieve the goal,I'm considering to modify the codes of llvm-gcc's collect2 to make it call llvm-ld automatically when receive certain options.

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

Hi, I don't think just use gold-plugin even modified is enough for the task of building a whole-program bc file. When we want to build a whole-program bc file by a general solution(I meant that we can use such a method for all kinds of build system),we need not only a gold-plugin to do what llvm-ld does,but also some mechanisms,not a simple trick to modify the env variables,to run

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

...st there. and I use collect2 -plugin to link the generated object files manually,everything is OK, the generated executable can also give the expected result. Is it a bug for llvm-gcc can not search the correct plugin library file??If not,what's the matter with my operations? Best regards.

Hi,all I have installed the gold-plugin and it can run correctly,but I still have another two questions: 1.Can gold-plugin generate a bitcode file: >From the document and also my experience on using it,"ld -plugin...." will only generate an executable by link several LLVM bitcode file together,but how to make it generate a whole-program bitcode file?(even archieve it manually is

Hi,all I'm using ubuntu8.04 and I'm installing gold-plugin along with the document of that, After I built the binutils and LLVM with plugin enabling,and I also replace ld with ld-new which supports plugin,I tried to compile a hello world program by this: llvm-gcc -use-gold-plugin a.a b.o -o hello which is similar with the example in the document,it tells me that libLLVMgold.so can not
