* Fix a bug that showed up when debugging dynamically linked programs.John Polstra1998-09-161-3/+13
| | | | | | | | | | | | | | | | | | | | | | References from GDB to "printf" and various other functions would find the versions in the dynamic linker itself, rather than the versions in the program's libc. This fix moves the GDB link map entry for the dynamic linker to the end of the search list, where its symbols will be found only if they are not found anywhere else. It was suggested by Doug Rabson, though I implemented it a little differently. I personally would prefer to leave the dynamic linker's entry out of the GDB search list altogether. But Doug argues that it is handy there for such things as setting breakpoints on dlopen(). So it stays for now, at least. Note, if we ever integrate the dynamic linker with libc (which has several important benefits to recommend it), this whole problem goes away. Notes: svn path=/head/; revision=39321

* Implement ldconfig functionality for ELF. The hints are stored inJohn Polstra1998-09-051-3/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints". These hints consist only of the directory search path. There is no hash table as in the a.out hints, because ELF doesn't have to search for the file with the highest minor version number. (It doesn't have minor version numbers at all.) A single run of ldconfig updates either the a.out hints or the ELF hints, but not both. The set of hints to process is selected in the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout" or "-elf" command line option. The rationale is that you probably want to search different directories for ELF than for a.out. "ldconfig -r" is faked up to produce output like we are used to, except that for ELF there are no minor version numbers. This should enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports even for ELF. I implemented the ELF functionality in a new source file, with an eye toward eliminating the a.out code entirely at some point in the future. Notes: svn path=/head/; revision=38836
