Hi, I just got a bug report that klibc doesn't compile on s390: KLIBCCC usr/klibc/libgcc/__clzsi2.o KLIBCCC usr/klibc/libgcc/__clzdi2.o usr/klibc/libgcc/__clzdi2.c: In function `__clzdi2': usr/klibc/libgcc/__clzdi2.c:24: warning: implicit declaration of function `__builtin_clz' This looks like a common problem, because __builtin_clz is available since gcc 3.4, while the kernel should compile even with gcc 3.2. Looks like...

Hi all, I've encountered a couple of minor build issues on Solaris that have crept in since 2.5, fixes below: 1. In lib/Target/X86/X86JITInfo.cpp, there is: // Check if building with -fPIC #if defined(__PIC__) && __PIC__ && defined(__linux__) #define ASMCALLSUFFIX "@PLT" #else #define ASMCALLSUFFIX #endif Which causes a link failure due to the non-PLT
