I've just looked at the Clang documentation, and it says: MemorySanitizer requires that all program code is instrumented. This also includes any libraries that the program depends on, even libc. Failing to achieve this may result in false reports. For the same reason you may need to replace all inline assembly code that writes to memory with a pure C/C++ code. So, indeed, one should recompile GMP with Clang and without asm code. (BTW, if one needs to also recompile libc, this seems rather impracticable.) -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) _______________________________________________ gmp-bugs mailing list gmp-bugs@gmplib.org https://gmplib.org/mailman/listinfo/gmp-bugs
