Bug ID: 49562
Summary: WORDSIZE is incorrectly defined as 64 on Linux SPARC
with -mcpu=v9 and -m32
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
Assignee: unassignedclangb...@nondot.org
Reporter: glaub...@physik.fu-berlin.de
CC: jrt...@jrtc27.com, llvm-bugs@lists.llvm.org,
neeil...@live.com, richard-l...@metafoo.co.uk,
r...@gcc.gnu.org
Test case:
glaubitz@gcc202:~$ cat test.c
#include <stdio.h>
#include <bits/wordsize.h>
int main () {
#if __WORDSIZE == 32
printf("Hello 32-bit World!\n");
#elif __WORDSIZE == 64
printf("Hello 64-bit World!\n");
#endif
return 0;
}
With gcc:
glaubitz@gcc202:~$ gcc test.c -o test -m32 -mcpu=v9
glaubitz@gcc202:~$ file test
