search for: _rtld_global

Hi, I am trying to compile a dynamic loader using LLVM. Part of the IR for this loader looks like this: @_rtld_local = hidden alias %struct.rtld_global* @_rtld_global @_rtld_global = unnamed_addr global %struct.rtld_global { ... } The purpose of _rtld_local is to allow _rtld_global to be referenced without using the GOT, as this global is accessed before the dynamic loader initialises the GOT. However, LLVM sees through the alias and resolves references to _rt...

Oops, missed this message. I think there was some reason why I thought protected visibility would not work, but I just tried it and it turns out that it does. I'll...

...__libc_dlopen_mode@@GLIBC_PRIVATE U __libc_dlsym@@GLIBC_PRIVATE U __libc_fatal@@GLIBC_PRIVATE U __libc_pwrite@@GLIBC_PRIVATE w __pthread_clock_gettime@@GLIBC_PRIVATE w __pthread_clock_settime@@GLIBC_PRIVATE U __pthread_unwind@@GLIBC_PRIVATE U _rtld_global@@GLIBC_PRIVATE But I couldn't find where these symbols are defined (e.g. __libc_pwrite@@GLIBC_PRIVATE). The workaround that I found is to add the following line to the spec file: "provides: libc.so.6(GLIBC_PRIVATE)(64bit)" I guess that there should be a better solution for th...

Hi what do you guys use for shared calendars these days? I've been using corporate time but that is now part of Oracle suite so looking for an alternative that is hopefully open source/free to complete my 'get away from exchange' package. thanks
