Raw Normal View History

Fixed `make depend' and related bogons. LDFLAGS was used for 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).

Imported NetBSD's ld for shared libs.

PROG= ld.so
Update to handle new version ld.so.hints and info in executable for configurable fallback search paths, as well as new crt interface version. 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

# As there is relocation going on behind GCC's back, don't cache function addresses.
PICFLAG=-fpic -fno-function-cse
This is Paul K's latest set of ld changes. A commit was necessary at this late stage due to the fact that link.h was copyright Sun Microsystems. This version of ld sync's us up with NetBSD's ld and supports compatablily with NetBSD's -[zZ] flags (which we had reversed). Compiling with this new ld will give you RRS warnings for libraries which do not contain .type infomation - these wsarnings are harmless and will go away as soon as you recompile your libraries (cd /usr/src; make libraries).

ASFLAGS+=-k
Add dependencies on libraries to DPADD. Someday this should be done automagically. -lfoo has to be right to work, but ${LIBFO0} is too easy to forget or misspell; nothing checks it and it should be different for shared libraries.

DPADD+= ${LIBC:S/c.a/c_pic.a/} ${LIBC:S/c.a/gcc_pic.a/}
Due to the deletion of the gcc support from libc we need again the -lgcc_pic library. rtld uses the udivd3 routine from it. Repeat the bug by simply compiling ld on current.

Use `install -C' instead of lots of shell commands to install ld.so as atomically as possible. (Immutable targets can't be renamed without opening a window when neither the source nor the target is immutable. Perhaps there should be a rename_immutable syscall to do this if unsetting the immutable flags would work.)
