Hey all, I was wondering if clang/LLVM has support to compile glibc in its entirety? The only thing I could find of recent was this thread saying the only way it could really be done is to use the dragonegg plugin with gcc... https://groups.google.com/forum/#!topic/llvm-dev/pmZYVNTrVYQ [LLVMdev] clang/llvm with glibc 8 posts by 5 authors [X] [X] Dave Buehmann [X]

Roland says the main blocker for now is support for nested functions, he thinks the rest should be straightforward. There was apparently a post to the glibc mailing list about this.

Hello. I have an issue with SSHFP lookups using "VerifyHostKeyDNS=yes" and "options edns0" in /etc/resolv.conf (glib >= 2.6). getrrsetbyname() calls res_query() with a maximum buffer size of 65536. The glibc resolver truncates this value to 16 bits, reducing the query's advertised buffer size to 0. BIND appears to ignore it while Unbound returns a server failure.

Hello all-- Due to a proposed changeover to build machines for a project I'm involved with, I need at least glib 2.19. Right now I have glib 2.12, and even on CentOS7-32 bit, what I see is glib 2.14. Is a higher glib available anywhere that might work with my current 6.8. I see I can download it from SourceForge but I am wondering what the results might me. I really like CentOS and would

Hi James, I will look into the RedHat newlib library, however, we def are looking for a solution for glibc, but maybe newlib would be a good way to go to test our complete workflow before putting an effort to generate control flow graphs for glibc. btw. I did have another question, hopefully you would be able to answer, what we are looking to do is to get the control flow graph including some

Hi, I read on the gentoo website http://en.gentoo-wiki.com/wiki/Llvm that glibc cannot be compiled using llvm because of some GNU extensions which LLVM does not support. Has there been any success in compiling glibc using LLVM so as to get the bytecode? We are looking to do whole program analysis to look at control flows including those in libc... we were hoping that we could get the control

Hi Nipun, As you say, glibc is rather GCC -oriented. I certainly haven't tried this myself, but have you thought of using an alternate C library such as RedHat newlib? That can certainly be compiled by clang (we do it every night).

We have a third party shared library from a vendor that requires glib 2.15 or newer. We are using CentOS 6.6 which comes with glibc 2.12, and I know it can?t be replaced as it?s an integral part of the OS. However, is it possible to build a glib 2.15 RPM from source to be installed in /opt/centos (or somewhere else other than /usr/lib) so that I can link the one application that requires the

Purpose: I implemented a pass on LLVM backend that changes the output format of *ARM* assembly/binary (e.g add a jump at the end of each basic block to eliminate fall through). By calling: llc -march=arm somefile.bc it generates expected arm assembly/binary that runs properly on arm gnu linux (I use qemu-arm and gem5 to simulate it). Now I want to do the same thing on standard c library, but

** NOT WORKING ** This patch shows how to integrate libnbd and the glib main loop. Posted mainly as a point of discussion as it doesn't quite work yet. Rich.

To whom it may concern, Is there a way to build glibc with clang/llvm? I’m working on enabling llvm-cov for my compiler which is a totally new arch with a libc.a built from newlib. I successfully built compiler-rt but when I typed the command ` clang++ --target=xxx -fprofile-instr-generate -fcoverage-mapping foo.cc -o foo`, the linker failed because of undefined reference to

Hi. Actually from reading the README, it seems to imply that it can be built with Clang 6.0.0 and above now, though it does incorporate a lot of patches not specific to Clang building so you will end up with them as well: ---------------------------------------------------------------------------- BUILDING GRTE WITH CLANG GRTE v5 and later can also be built with clang and (optionally) lld.

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.
