Dear Maintainer, * What led up to the situation? Compiling a simple hello world program written in C works fine with clang compiler unless any of the options -O4 or -emit-llvm is specified. clang -O4 hello.c -o hello clang -emit-llvm hello.c -o hello For this, Also ld has to be symlinked to the gold linker (/usr/bin/ld.gold) as the ld.bfd linker DOES NOT support the -plugin argument, which clang passes to the linker! * What was the outcome of this action? me@debian:/tmp$ clang -v -O4 hello.c Debian clang version 3.2-10 (tags/RELEASE_32/final) (based on LLVM 3.2) Target: i386-pc-linux-gnu Thread model: posix "/usr/bin/clang" -cc1 -triple i386-pc-linux-gnu -emit-llvm-bc -disable-free -disable-llvm-verifier -main-file-name hello.c -mrelocation-model static -fmath-errno -masm-verbose -mconstructor-aliases -fuse-init-array -target-cpu pentium4 -target-linker-version 2.23.52.20130620 -momit-leaf-frame-pointer -v -resource-dir /usr/bin/../lib/clang/3.2 -fmodule-cache-path /var/tmp/clang- module-cache -internal-isystem /usr/local/include -internal-isystem /usr/bin/../lib/clang/3.2/include -internal-isystem /usr/include/clang/3.2/include/ -internal-externc-isystem /usr/include/i386 -linux-gnu -internal-externc-isystem /usr/include/i486-linux-gnu -internal- externc-isystem /usr/include -O3 -fdebug-compilation-dir /tmp -ferror-limit 19 -fmessage-length 125 -mstackrealign -fobjc-runtime=gcc -fdiagnostics-show- option -fcolor-diagnostics -o /tmp/hello-KdAKtA.o -x c hello.c clang -cc1 version 3.2 based upon LLVM 3.2svn default target i386-pc-linux-gnu ignoring nonexistent directory "/usr/bin/../lib/clang/3.2/include" ignoring nonexistent directory "/usr/include/i486-linux-gnu" #include "..." search starts here: #include <...> search starts here: /usr/local/include /usr/include/clang/3.2/include /usr/include/i386-linux-gnu /usr/include End of search list.
