Hi all,
during compiling 2.6.0-test5-pa6 with gcc-3.3, i noticed some warning of
type:
[snip]
CC fs/exec.o
fs/exec.c: In function `format_corename':
fs/exec.c:1219: warning: long unsigned int format, time_t arg (arg 4)
[snip]
for which I would suggest the following patch:
hpalin:/Debian-apt/SRC/linux-2.6.0-test5-pa6/fs# diff -Nau exec.c.Orig
exec.c.new
--- exec.c.Orig 2003-09-10 18:18:40.000000000 +0200
+++ exec.c.new 2003-09-16 23:55:12.000000000 +0200

struct timeval tv;
do_gettimeofday(&tv);
rc = snprintf(out_ptr, out_end - out_ptr,
- "%lu", tv.tv_sec);
+ "%lu", (unsigned long int)tv.tv_sec);
if (rc > out_end - out_ptr)
goto out;
out_ptr += rc;
I would like your opinion before submiting (hmm to Andrew I presume?)
Thanks in advance,
Joel

This looks ok to me, although you don't need the extra "int".
I noticed in include/asm-parisc/posix_types.h we have:
/* Note these change from narrow to wide kernels */
#ifdef __LP64__
typedef unsigned long __kernel_size_t;
typedef long __kernel_ssize_t;
typedef long __kernel_ptrdiff_t;
typedef long __kernel_time_t;
#else
typedef unsigned int __kernel_size_t;
typedef int __kernel_ssize_t;
typedef int __kernel_ptrdiff_t;
typedef int __kernel_time_t;
#endif
On narrow kernels, int and long are the same. So, why not use long
for both narrow and wide? Then, the ifdef can be eliminated.

I'd rather not add these. They are only warnings, after all.

I think it's because gcc complains ;-)

Possibly, but the pa seems to be about the only port doing this.

We're one of the few ports that builds both 32 and 64 bits from the same
port (actually, we were the first). MIPS recently converted, and S390
before them. PPC might in the future, and I doubt Sparc ever will.

Sparc won't go there - sparc32 and ultra-sparc are really two different
things...
