With attached .config:
$ make
...
CC editors/diff.o
cc1: warnings being treated as errors
editors/diff.c: In function 'diffreg':
editors/diff.c:646: error: assignment discards qualifiers from pointer target type
make[1]: *** [editors/diff.o] Error 1
make: *** [editors] Error 2
I added a (char*) cast to suppress it.
Testing:
$ ./runtest diff
PASS: diff of stdin
PASS: diff of stdin, no newline in the file
PASS: diff of stdin, twice
PASS: diff diff1 diff2/subdir
PASS: diff dir dir2/file/-
PASS: diff of dir and fifo
PASS: diff of file and fifo
PASS: diff -rN does not read non-regular files
Ok!
Size comparison with the version before rewrite:

(add/remove: 7/12 grow/shrink: 2/4 up/down: 5516/-4770) Total: 746 bytes

It looks good - it shrank! But now it uses libm.
Can you avoid it by using approximate sqrt()?
See, for example, http://en.wikipedia.org/wiki/Integer_square_root
Looking at the code.
static int read_char(int fd)
{
char tmp;
ssize_t count = safe_read(fd, &tmp, sizeof(tmp));
if (count < 0)
bb_error_msg_and_die("read_char");
return count ? tmp : EOF;
}
One syscall per byte? This is *very* inefficient:
# strace -oz1 ./busybox_old diff -u busybox_unstripped.map busybox_unstripped.map
# strace -oz2 ./busybox diff -u busybox_unstripped.map busybox_unstripped.map
# wc -l z1 z2
4799 z1
4986284 z2 <--------- !!!!
# time ./busybox_old diff -u busybox_unstripped.map busybox_unstripped.map
real 0m0.004s
user 0m0.002s
sys 0m0.001s
# time ./busybox diff -u busybox_unstripped.map busybox_unstripped.map
real 0m1.970s
user 0m0.456s
sys 0m1.512s
Please use FILE* based reading, it will do buffering for you.
if (fd[0])
close(fd[0]);
if (fd[1])
close(fd[1]);
fd == 0 is also a valid file descriptor. < 0 aren't.
struct cand *clist = xmalloc(clistlen * sizeof(struct cand));
int *klist = xmalloc((n + 2) * sizeof(int));
clist[0] = (struct cand){0};
klist[0] = 0;
...
ix[i] = xmalloc((nlen[i] + 2) * sizeof(ix[i][0]));
ix[i][0] = 0;
Maybe use xzalloc to achieve zeroing with less code.
/* shellsort CACM #201 */
static void sort(struct line *a, const int n)
Why not reuse qsort from libc?
/* This function adds a filename to dl, the directory listing. */
static int FAST_FUNC add_to_dirlist(const char *filename,
struct stat *sb UNUSED_PARAM,
union {
void *userdata;
struct dlist *l;
} __attribute__((transparent_union)) user,
int depth UNUSED_PARAM)
A comment is in order. Or maybe avoid using such gcc'isms
if not absolutely necessary.
static void print_status(int val, char *_path[2])
names with leading _ are reserved to libc/compiler, don't use them.
Looking forward for the next iteration of the patch.
