Bug #: 14696
Summary: Clang 3.2 Binaries for Ubuntu-12.04/x86 build 64-bit
executables by default
Product: new-bugs
Version: 3.2
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P

I'm having trouble with the Clang 3.2 binaries for Ubuntu 12.04/x86 from here:
http://llvm.org/releases/download.html#3.2. It looks like Clang is trying to
build for 64-bit even though I'm on a 32-bit system. Passing the -m32 flag
shouldn't be necessary, surely?
I'm running Ubuntu 12.04 32-bit.
$ cat hello.c
#include <stdio.h>
int main(int argc, const char *argv[]) {
printf("hello world\n");
}
$ uname -i
i386
$ clang -v
clang version 3.2 (tags/RELEASE_32/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix
$ file $(which clang)
