Hi, There is a little bit awkward thing. If I need to use the newlibc printf function regardless stdint.h is compiler specific implementation, I should remove or block newlibc's stdint.h and the others because as you know clang already stdint.h (glibc compatible??) header but it is not standard library full set, right? On the other hand, even if I want to use ot...

Hi, all, I am using llvm-gcc --emit-llvm to generate byte code. With llvm readable ll format, I found some standard C library function such as llvm.memset. In fact, I'm trying to compile newlibc with llvm, I do not need this kind of llvm functions. How can I remove them during the compilation? Best regards, -- Hao Shen

...is is not a C library function, it is an LLVM intrinsic. An intrinsic is analogous to a builtin in gcc. An intrinsic may be expanded out into a code sequence by the compiler, or may get turned into a library call (which sounds like is what you are seeing). > In fact, I'm trying to compile newlibc with llvm, I do not need this > kind of llvm functions. How can I remove them during the compilation? You can't avoid them. The same problem exists with gcc: you can't always avoid having gcc use the gcc memset builtin. However it has to be said that gcc generates its memset builtin l...

Hello, James Molly. Thank you for your advices. Now I aware that this is the problem of stdint.h. And, codesourcery toolchain also has stdint.h header file at same place of stdio.h Generally, Clang has "lib/clang/3.0/include" default search path. If I added codesourcery toolchain path for stdio.h with -I option, stdint.h has been loaded at the specified toolchain path first cuz

Dear all. I built the LLVM 3.0 rc4 with Clang front-end in windows os env. (also with -DLLVM_TARGETS_TO_BUILD=all option) For arm neon intrinsics testing, I tried to compile some codes, which are included a few neon intrinsics. Although I got a well done bitcode on ubuntu build pc, it shows some errors when compile the codes on windows. Could you let me know why occurred errors? is this just a

Hi, I‘m trying to install vTPM based on Xen-4.2.2, linux-kernel 3.9.1 (Dom0) and TPM emulator. However, I cannot find the TPM backed driver in this version of Dom0 linux kernel. There is no CONFIG_XEN_TPMDEV_BACKEND in the kernel config file. The config file for Dom0 is attached. Maybe it provides some useful information. So, how to install a Xen TPM backend driver in the Dom0 linux-kernel.
