Hi Heyu Zhu, > Then then the error is: > > /tools/IUS611/tools/lib/libgcc_s.so.1: version `GCC_4.2.0' not found > (required by /usr/lib/libstdc++.so.6) you can get this if you compile C++ code using a different compiler to your system compiler. Based on the error message, your system compiler is gcc-4.2 and the other compiler is probably gcc-4.3 or later. What has happened

According to your description i should not use the system libstdc++ and i need to specify the OTHER compiler libstdc++. But i don't where the OTHER compiler libstdc++ is. Is the OTHER compiler libstdc++ contained in llvm-2.5.tar.gz? if not where can i get it? 2009/10/20, Duncan Sands <baldrick at free.fr>: > > Hi Heyu Zhu, > > Then then the error is: >>

Hi everyone, It seems variable arguments is not support by mips backend in llvm-2.6. int func(int i, ...) { return 0; } llvm-gcc func.c -emit-llvm -c -O3 -o func.bc llc func.bc -relocation-model=static -march=mips -O0 -o func.s Command llc fails: llc:SelectionDAGBuilder.cpp:6440:void llvm::SelectionDAGISel::LowerArguments( llvm::BasicBlock):Assertion 'Invals.size() ==

Hi everyone, There are 16 GPRs in my RISC, but in fact GPR13 is read-only and connected to output of an A/D converter. It would be very convenient if i could bind a register variable with GPR13. Because i am a newbie i don't know how my llvm backend can support that. I plan to implement it as below. A. first declare a global variable in c-code int ADC asm("GPR13"); B. If

Hi everyone, I am puzzled by several instruction defines in MSP430. 1 def MOV16rr : Pseudo<(outs GR16:$dst), (ins GR16:$src), "mov.w\t{$src, $dst}", [ ]>; Because it's an empty dag pattern[ ], by what does instuction selector select intruction 'MOV16rr'? 2 let canFoldAsLoad = 1, isReMaterializable = 1, mayHaveSideEffects =

Hi everyone The c code is like below extern int function_0(int, int); int main(){ return function_0(8, 9); } I compile it as below llvm-gcc main.c -emit-llvm -c -O3 -o main.bc llc main.bc -relocation-model=static -march=mips -O0 -o main.s It seems no argument is provided to function_0 ... addiu $sp, $sp, -8 sw $ra, 0($sp) jal function_0

For systems that have gcc 4.2 natively installed, like the current Debian testing, the compiler gets GCC_4.2.0 version errors. It isn't easy to work around b/c xgcc wants to link

Hi, 1. This instruction is not selected automatically by the instruction selector. The instruction combine / select stages insert registercopies, and they are expanded later on by the copyRegToReg() function provided by the MSP430InstrInfo to this MOV16rr. 2. ReMaterializable means there is no need to find a way to preserve the value in a register : the instruction can be just be reissued

Hi, The gcc version in my system is 3.4.6 During make display error message and stop cc1plus:error: unrecognzied command line option -Wno-variadic-macros Must i update gcc to version 4.2.0 or above to resolve the problem?

Hello everyone, I want to generate machine code for target thumb, so run with bit code test.bc llc -march thumb test.bc -filetype obj -o test.o It doesn't generate test.o but show a message: "target doesn't support generation of this file type!" What's wrong? Thanks -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi everyone, I try to add an instruction to x86. The instruction is a multiply-add instruction MULADD A, B, C; //A = A + B * C. I use the instruction by inline assemble as below int x, y, z; ..... .... x = 0; asm("MULADD %0, %1, %2":"=r"(x):"0"(x), "r"(y), "r"(z)); ..... .... The backend does allocate registers %edx, %edi, %esi for x,y, z

Hi, I have seen the bug http://llvm.org/bugs/show_bug.cgi?id=896 Maybe it is a non-issue but I had some trouble with this. I am running Debian sid and were no longer able to compile llvm. /home/fred/llvm/build/gcc/xgcc: /home/fred/llvm/build/gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6) The installed version have this symbol. strings

That is a sign that your native GCC is not new enough, upgrading to 4.2 or later should

Hi Duncan, Is it to say llvm-2.5 has no assembler and linker for target thumb and llvm-2.5 can only generate assembler file for the time being?

Hi, I'm still working on the Fedora Extras package for LLVM. Because of the Fedora requirement that all packages in Extras be built from source, I must build the dreaded C Front End. :) I think I've mostly got things set up correctly, but I've found what I suspect is a tricky problem: make[1]: Leaving directory `/home/adam/rpmbuild/BUILD/llvm-1.8/llvm-gcc4-obj/gcc' Checking

Hi all, I'm trying to configure Nut to connect to an APC BackUPS Pro 900VA. This ups uses a serial port on which _simple_ or _smart_ signaling should be spoken. I've connected the UPS to a serial port using the original 940_0128A cable from APC. Unfortunately I've not yet managed to read any data from the ups. If I try to load the apcsmart driver it tells me that it cannot communicate
