I've experienced GCC induced eyeball-clawing.... Not pretty!

As we've already seen, David Chisnall prefers hacking LLVM over GCC (see http://www.informit.com/articles/article.aspx?p=1215438): "In contrast, every time I look at the GCC code, it takes two people to prevent me from clawing my eyeballs out." I'm sorry to report that so-far I have had the opposite experience. Some years ago, I ported binutils (via CGEN) and GCC to an

Thanks. It worked for a few more compilation lines. I now get the following linker error: undefined reference to llvm::MemoryBuffer::getNewMemBuffer(unsigned long, llvm::StringRef) I am surprised since the linker compile line already links with a whole bunch of llvm libraries ...

I got this one fixed by rebuilding llvm Debug (oups). I had an old version. I now seem to have a classical message: version GLIBCXX_3.4.14 not found. I am indeed building llvm-gcc using gcc4.5. Is this the problem ? The fix to this problem indicated in README.LLVM does not help .. Thanks Romain On Thu, Aug 12, 2010 at 6:43 PM, Romain Pechayre <rpechayr at gmail.com> wrote: > Thanks.

Ok. Thank you for your input. New questions :) : - Is the dev package basically the source code of gcc 4.2 ? Isn't it already fully included in llvm-gcc code base ? - How should I include bison+flex when I have installed Do I need to put additional flags to configure script ?

hello every body. Here with I have attached the patch which compile the llvm-gcc using nightly tester script. This patch add the following capabilities to the NewNightlyTester.pl script. 1. Checkout the llvm-gcc4.2 source from the SVN. 2. Compile the checkout llvm-gcc4.2 source tree. 3. Gather the configure/make out put informations. 4. Add the (3) informations to the %hash_of_data hash to be

I need to add, also you'll need bison+flex.

Thanks :-) One last thing. It seems like the patch has a lot of whitespace changes. Could you create the diff with the -b option? -bw On Mon, Jul 7, 2008 at 11:49 AM, Rajika Kumarasiri <rajikacc at gmail.com> wrote: > hi Bill, > Thanks for the comments.

Hello every body, I am a Computer Science and Engineering final year undergraduate in here [1]. As you all aware of GSoC 2008 program is now on [2]. I would like to participate in this on a project on LLVM. The reason why I selected LLVM is I am really interested in compiler theory. I took the one semester course on compiler theory and developed a lexical analyzer in C for a subset of Javascript

Hi Greg, I understand your frustration. I've been on this mailing list for a little over a year hoping that by osmosis I could get a a better handle on writing a back end for LLVM. Although I feel more comfortable with the nomenclature, I still do not have a clue as to how to begin (actually I do, but it sounds more dramatic saying it this way). I've read the documentation, but

hi Bill, Thanks for the comments. I'll update the patch according to that. -Rajika On Mon, Jul 7, 2008 at 11:56 PM, Bill Wendling <isanbard at gmail.com> wrote: > On Mon, Jul 7, 2008 at 11:10 AM, Rajika Kumarasiri <rajikacc at gmail.com> > wrote: > > hello everybody, > > > > I have added few improvements to my patch.

hi, I am getting following compilation error while compiling llvm. I installed the missing libs. using my package manager (and there are in /usr/loca/lib path). Any clue to fix the problem.

Rajika, A couple of comments: - You should provide a way to specify where llvm-gcc is built (just like llvm). - I would highly recommend allowing the user to only update llvm-gcc and not check it out from scratch each time. Checking out llvm-gcc is very time consuming. You would need to make sure that llvm and llvm-gcc have the same rev number and nuke the llvm obj/install dirs so you get a

>From a cached version of the Getting Started Guide, I have found: "GCC 3.4.4 (CodeSourcery ARM 2005q3-2): this compiler miscompiles LLVM when building with optimizations enabled. It appears to work with "make ENABLE_OPTIMIZED=1 OPTIMIZE_OPTION=-O1" or build a debug build." I'm trying that now. -Puyan On Sun, Feb 21, 2010 at 1:22 AM, Rajika Kumarasiri <rajika at

I am going to post my first chapter, just to see if it is acceptable. Any feedback is good feedback for me.
