Good day Nathan, If your using the stock GCC with Solaris, I am sorry to inform you its broken, Please see: http://llvm.org/docs/GettingStarted.html#brokengcc Please be warned as your get miss compiles and things will do strange `stuff`. As can be seen here, the reverse is true for both the GNU binutils and XPG4 versions of `nm' : -bash-3.2$ /usr/xpg4/bin/nm -p -u `find . -name

I have a question on the LLVM JIT I did some brief memory reading one day and I found that a call to a non-library function is resolved by the X86CompilationCallback, but the X86CompilationCallback is reached through a trampoline. why can not the generated code jump to the X86CompilationCallback function directly ? 0x2b0a6a4d103b: mov $0x2b0a6a561010,%rax 0x2b0a6a4d1045:

The address of the callee may be more than 2 GB away in memory, which cannot be encoded as an immediate offset in the call instruction. So, the value is first materialized with a mov instruction which can encode the immediate and then jumped to through a register.

I understand that we need to push the address to a register then branch using the register. But i am asking why there is a trampoline there such that a call to foo is first branched to an snippet and the snippet branches to the X86CompilationCallback. is this snippet necessary ?

Hi! We are running llvm jit x86 on MS Visual Studio 2005. It seems there is a bug in asm code in function X86CompilationCallback in file X86JITInfo.cpp. Current code sets stack pointer to invalid value in instruction "and esp, 16". Depending on current stack pointer value it sometimes overwrites ecx and edx registers with next three lines. We have fixed this problem by changing this

My 7 zip file manager says that the mingw binary is corrupt for llvm 1.9. I suppose that means that those of us running windows have no hope of getting llvm right now? Someone reported this earlier but the situation remains unchanged. -Matt

Hello everyone, I've run across a problem building LLVM 2.7 with Mingw on Win7. When I try make VERBOSE=1, it churns away happily for a while and then produces: /c/Perl/bin/perl /c/Programs32/llvm-2.7/utils/GenLibDeps.pl -flat /c/Programs 32/llvm-2.7/obj/Release/lib "/mingw/bin/nm" > /c/Programs32/llvm-2.7/obj/tools/ llvm-config/LibDeps.txt.tmp 'c:' is not recognized as

Hi I found utils/GenLibDeps.pl cann't run on Windows, so I fix it, made a patch on svn-110435. I submit this patch, hope it can be accepted. Thanks for your time.
