[cfe-dev] ccc return code

[Török Edwin]

Hi,

ccc returns exitcode 0, even on failure:
$ cat x.c
#include <sys/int_types.h>
$ /home/edwin/llvm-svn/llvm/tools/clang/utils/ccc -c x.c; echo exitcode:$?
clang -emit-llvm-bc -x c -o x.o x.c
x.c:1:10: error: 'sys/int_types.h' file not found
#include <sys/int_types.h>
         ^
1 diagnostic generated.
exitcode:0
$ clang -emit-llvm-bc -x c -o x.o x.c; echo exitcode:$?
x.c:1:10: error: 'sys/int_types.h' file not found
#include <sys/int_types.h>
         ^
1 diagnostic generated.
exitcode:1

The exitcode in python is 256, if I add an if to make 256 into 1, it works:

$ /home/edwin/llvm-svn/llvm/tools/clang/utils/ccc -c x.c; echo exitcode:$?
clang -emit-llvm-bc -x c -o x.o x.c
x.c:1:10: error: 'sys/int_types.h' file not found
#include <sys/int_types.h>
         ^
1 diagnostic generated.
exitcode:1
