Hello all, I have replaced the llvm-gcc shipped with the Xcode by the latest version and I was wondering if I have missed something... (everything *seems* to work). Here's what I did: 0. Checkout LLVM (and clang) + llvm-gcc 1. Build LLVM (with clang) and install into /Developer/usr/local : # mkdir llvmobj # cd llvmobj # CC=gcc-4.2 CXX=g++-4.2 ../llvm/configure

Wouldn't it be slightly cleaner to mark the distinct objects in the LLVM intermediate representation? This would make the default

This patch eases building clang when present in the source tree. Since clang is revlocked to llvm, one usually updates them together, and builds them together.

Hi all, I've previously posted this patch on llvm-commits, but due to a lack of replies, and the fact that this patch is more something to discuss than something to apply, I'm posting this again here. While working on my own backend, I found that things got really messy real quickly, partly caused by the fact that all .cpp files must be in the same directory (lib/Target/TargetName).

Oscar, I be willing to donate some machine time to you. How about a 2 x 3GHz Dual Core Intel Xeon with 8GB? The question is how to get past the NAT. Email me privately if interested.

Hi, > gcc: gcc version 4.1.2 20070925 (Red Hat 4.1.2-33) most likely the version of gcc you are using is broken. See http://llvm.org/docs/GettingStarted.html#brokengcc Ciao, Duncan.

Hi, I am just starting a new project. I found that the above script rejects Autoconf versions later than 2.59, whereas it ought to accept them, imho. I had to edit the scrip to be able to use it with Autoconf 2.61. Also, aclocal gave the following warning: /usr/share/aclocal/oaf.m4:4: warning: underquoted definition of AM_PATH_OAF /usr/share/aclocal/oaf.m4:4: run info '(automake)Extending

Reports arrived indicating that the LLVM cmake-based build system is lacking some OS X specific work, which seems to be the OS of choice for quite a few LLVM developers. I know there are sites out there that offer Linux shell accounts. Is there something similar for OS X, where building LLVM would be possible? A google search turned no solid results. Or would someone donate ssh access and approx.

Hi, When i wanted to build the llvm-gcc, i got the problem as following. ========================================================================================================================== cc1: /home/cllou/LLVM/llvm-2.4-dir/llvm-2.4/lib/Support/StringMap.cpp:177: void llvm::StringMapImpl::RemoveKey(llvm::StringMapEntryBase*): Assertion `V == V2 && "Didn't find

It seems that --enable-shared builds are not used by LLVM developers because the executables starts slowly. I guess this is related to the number of symbols the dynamic linker has to resolve. If we could reduce the symbols exported to those which are required, maybe the startup time would become bearable. One way of doing this is to add annotations to each public class and function (such as

Hi, I don't know enough C to know for certain if this is a programmer or compiler error: In a Objective-C source file I have: . static const char sessionEntriesKVO = ' '; . Later I use that variable as a ID by taking it's address like this: [feedManager addObserver:self forKeyPath:@"sessionEntriesCount" options:0 context:&sessionEntriesKVO]; and later . if
