2004-08-10Optimze _dl_memset() for PowerPC.Joakim Tjernlund
Other arches may also benefit from this iff it can do unaligned stores.

i was sticking some libraries in non-standard (i.e. not-hardcoded) paths and then updating ld.so.conf accordingly ... oddly though, i couldnt get binaries that linked against those libraries to run ... `ldconfig -v` showed the required libraries being detected/cached, so something seemed wrong ... turns out the libraries were being tagged as LIB_ELF_LIBC0 in the cache and the loader currently only accepts LIB_ELF_LIBC{5,6} ... since readsoname.c in ldconfig defines needed_tab with the mapping 'libc.so.0' -> LIB_ELF_LIBC0 it seems like the loader should accept this type too find attached a small patch which adds LIB_ELF_LIBC0 along side LIB_ELF_LIBC{5,6} as an accepted lib type in the loader when dealing with the ld.so.cache file

in libdl, the XXFLAGS is set incorrectly if DODEBUG=y ... it has 'I.' added to it instead of '-I.' ... this of course pisses of gcc :) find attached a patch that cleans up the XXFLAGS setting so as to minimize this kind of thing ... when asked, mjn3 said it was a kosher idea ;) and later writes: hmm it seems ldso also utilizes USE_CACHE in the code (but LIBRARY_CACHE never propogates down to the Makefiles) so the fix is to add $(LIBRARY_CACHE) while setting $(XXFLAGS) Applied with minor fixes and also fixed up ldso/Makefile to match libdl/Makefile.

while playing around with Gentoo on uClibc, i hit some troubles with ldconfig first, i found that it kept trying to read 'etc/ld.so.conf' ... it didnt want to read '/etc/ld.so.conf' ... looking at the source, the default conf file is defined as UCLIBC_RUNTIME_PREFIX "etc/ld.so.conf" ... all fine and dandy, but the utils/Makefile builds the .c files with this: -DUCLIBC_RUNTIME_PREFIX=$(R_PREFIX) i couldnt find where R_PREFIX was defined/used anywhere else, but i did find that every other time UCLIBC_RUNTIME_PREFIX was defined, it was set like: -DUCLIBC_RUNTIME_PREFIX=\"$(RUNTIME_PREFIX)\" changing the utils/Makefile to be like this fixed things for me next up, i found that i wasnt getting an /etc/ld.so.cache file when i ran `ldconfig` ... looking at the code, USE_CACHE needs to be defined ... Rules.mak has a line that reads LIBRARY_CACHE:=#-DUSE_CACHE by default, but then LIBRARY_CACHE is never used anywhere :) so the fix here is to add $(LIBRARY_CACHE) to the lines in utils/Makefile where the .c files are compiled perhaps a suggestion then ? in my mind it makes sense to utilize a cache file when running uclibc native but perhaps not while cross compiling ... so perhaps add LIBRARY_CACHE:=-DUSE_CACHE to the section in Rules.mak where LDSO is set to the uclibc linker (i.e. native) but set LIBRARY_CACHE:=#-DUSE_CACHE where LDSO is the $(SYSTEM_LDSO) (i.e. cross compiling) Applied with minor fixes.

PPC32, SPARC32/64 and S390 includes the PLT in its RELA size. This caused ldso to always do unlazy relocation of the JMPRELs. This patch fixes it.
2004-08-06Joakim Tjernlund writes:Eric Andersen
This patch makes -fpic work for PCC and optimzes the relcation by moving the cache flushing stuff to JMP relocs only. Actually PPCs ldso can only handle small GOT tables(<=8192 entries)anyhow, so it makes little sense to compile PPC with -fPIC. libuClibc shrunk from 340724 to 330780 bytes with -fpic.

Some utilities, such as valgrind, have a legitimate reason to know the address of the current brk. Since we know such utils will peek under our skirt, we might as well give them what they expect and not use a gratuitously different symbol name. -Erik

Hi Erik, I'm not sure why the NIOS support is not in uClibc -- perhaps the patch was rejected or never submitted? In any case, I'm playing with some NIOS stuff and created this patch against 0.9.26. The work was done by Microtronix. I'm not sure who else contributed to it. It would be great to have the NIOS support available in uClibc so developers don't have to go searching for these bits. Pete

actually match reality. In particular, _SC_GETPW_R_SIZE_MAX and _SC_GETGR_R_SIZE_MAX were causing us problems with programs such as libglib, since they were always returning -1, which is a bit smaller than the actual passwd and group max buffer sizes. -Erik

This is a patch for uClibc/libc/sysdeps/linux/mips/sys/procfs.h pulled from glibc CVS. This fixes gdb with threaded application (with glibc environment). Although debugging threaded programs seems not working on uClibc/mips yet, this patch will be required when it becomes working. This patch can be applied to any version of uClibc (including current CVS).
