clang-3.0+ (Fedora-17+) can do it:
$ clang -o t t.c -Wshorten-64-to-32
t.c:5:14: warning: implicit conversion loses integer precision: 'long' to 'int' [-Wshorten-64-to-32]
reported = longvar;
~ ^~~~~~~
t.c:6:12: warning: implicit conversion loses integer precision: 'long' to 'int' [-Wshorten-64-to-32]
missed = longvar + a - b;
~ ^~~~~~~~~~~~~~~
2 warnings generated.
For GDB:
CC=clang CFLAGS="-Wshorten-64-to-32" ./configure --disable-werror;make
I did not analyse how to possibly reformat the warnings for their easier later
processing. The patchset will need some extensions but I think the current
completed work can be completely easily reused.
Thanks,
Jan
