* Don't complain about no input files for `ld -f'. This fixes spuriousBruce Evans1997-04-251-2/+5

* Fixed `make depend' and related bogons. LDFLAGS was used forBruce Evans1997-04-161-10/+2
| | | | | | | | | | | | | | ld-specific flags. LDFLAGS is really for ld-related flags for cc, not for ld, and some flags, e.g., -Bshareable, mean completely different things to cc and ld. Having the wrong things in LDFLAGS also broke the standard ${PROG} target. This was kludged around by using a special rule that depended on LDFLAGS being bogus. Fixing `make depend' broke the special rule but fixed the standard rule (except in the DESTDIR case, which was handled more strictly here than elsewhere). Notes: svn path=/head/; revision=24979

* Fix a bug involving alias (N_INDR) symbols. When building a sharedJohn Polstra1997-02-011-2/+8
| | | | | | | | | | | | | | | | | | library with a shared object dependency that contained alias symbols, the linker incorrectly counted the number of symbols that would be written, resulting in a fatal internal error. Since our libc now contains some alias symbols (in "net/res_stubs.c"), this was sufficient to tickle the bug: "ld -Bshareable foo.so -lc". To fix it, I moved the accounting of alias symbols to a later point in the processing, where it is possible to count only those symbols that will actually be written to the output file. This fix is well-confined to affect alias symbols only. I have tested it with a full "make world". I am going to merge it into -2.2 after a few more days of living with it in -current.

| | | | | | | | | | | | If it is set to a nonempty string, then simply skip any missing shared libraries. This came up in a discussion long ago as a potentially useful feature at sysinstall time. For example, an X11 utility could be used without the X libraries being present, provided the utility had a mode in which no X functions were actually called. Notes: svn path=/head/; revision=21819

| | | | | | | | | | | | | | | | | | | | | | | | nonempty string, then function calls are relocated at program start-up rather than lazily. This variable is standard on Sun and SVR4 systems. The dlopen() function now supports both lazy and immediate binding, as determined by its "mode" argument, which can be either 1 (RTLD_LAZY) or 2 (RTLD_NOW). I will add defines of these symbols to <dlfcn.h> as soon as I've done a little more checking to make sure they won't cause collisions or bootstrapping problems that would break "make world". The "LD_*" environment variables which alter dynamic linker behavior are now treated as unset if they are set to the empty string. This agrees with the standard SVR4 conventions for the dynamic linker. Add a work-around for programs compiled with certain buggy versions of crt0.o. The buggy versions failed to set the "crt_ldso" member of the interface structure. This caused certain error messages from the dynamic linker to begin with "(null)" instead of the pathname of the dynamic linker. Notes: svn path=/head/; revision=21577

| | | | | | | | | | | | | | | | | | | | | | | | | that is stored in the hints file. If that search path contained a non-existent directory (one, say, that had been removed), and "ldconfig -m /a/perfectly/good/directory" was run, ldconfig returned an error status without printing an error message. This caused some confusing bombs when installing ports, in particular. I changed it so that non-existent directories from the stored search path are silently ignored. Only non-existent directories named explicitly on the command line are treated as errors. Also, a diagnostic is printed if and only if an error status is returned. In an unrelated fix, ldconfig now silently ignores any directories named on the command line when the "-r" option is given. Formerly, these directories incorrectly made their way into the "search directories" line of the listing. It really should be an error to specify directories together with "-r", but I don't have time to fix the manual page in that way right now. 2.2 Candidate. Notes: svn path=/head/; revision=19522

This enables the printing of error messages even for old executables, whose version of crt0.o is not able to print them. This fix closes PR bin/1869. The code in crt0.o for printing error messages from the dynamic linker is no longer used, because of this change. But it must remain, for backward compatibility with older dynamic linkers.

Also: - even faster getenv(), get all environment variable settings in a single pass. - ldd printf-like format specifications - minor code cleanups, one vsprintf -> vsnprintf (harmless) The library search sequence is a little more complete now. Before, it'd search $LD_LIBRARY_PATH (by opendir/readdir/closedir), then read the hints file, then read /usr/lib (again by scanning thr directory). It would then fail if there was no "found" library. Now, it does LD_LIBRARY_PATH and the hints file the same, but then uses a longer fallback path. The -R path is fetched from the executable if specified at build time, the ldconfig path is appended, and /usr/lib is appended to that. Duplicates are suppressed. This means that simply placing a new library in /usr/local/lib will work (the same as it did in /usr/lib) without needing ldconfig -m. It will find it quicker if the ldconfig is run though. Similar changes have been made to the NetBSD ld.so, but ours is rather different now due to John Polstra's speedups and fixes from a while back. The ldd printf-like format support came direct from NetBSD. Reviewed by: nate, jdp Notes: svn path=/head/; revision=18599

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | need this. Consider the following code: case 'O': output_filename = malloc(strlen(arg)+4); strcpy(output_filename, arg); strcat(output_filename, ".tmp"); real_output_filename = arg; return; The idea here is to malloc() a buffer big enough to hold the name of a supplied file name, plus ".tmp". So we malloc() 'size of filename' bytes plus 4, right? Wrong! ".tmp" is _FIVE_ bytes long! There's a traling '\0' which strcat() gleefully tacks on _outside_ the bounds of the buffer. Result: program corrupts own memory. Program SEGVs at seemingly random times. Bill not like random SEGVs. Bill smash. Know how I found this? I've been trying to bootstrap -current on my 2.1.0-RELEASE machine at work and I couldn't seem to get libc.a built because the linker would intermittently blow chunks while executing things like 'ld -O foo.o -X -r foo.o'. Since this is an initial bootstrap version of ld, it was linked against the 2.1.0 libc, who's malloc() behaves differently than that in -current. Presumeably ld -O doesn't blow up in -current, otherwise someone would have spotted this already. I don't know if this is a bug or a feature. Anyway. I'm changing the strlen(arg)+4 to strlen(arg)+5. Bah. Notes: svn path=/head/; revision=16191
