2002-11-19Aidan Van Dyk noticed that _toupper and _tolower were misbehaving.Eric Andersen
This corrects them, per SuSv3.
2002-11-19Per suggestion from Stefan Allius, change DO_MPROTECT_HACKS toEric Andersen
the more clear FORCE_SHAREABLE_TEXT_SEGMENTS.
2002-11-19Stefan Allius writes:Eric Andersen
I fixed two little bugs in ldso.c: - For LDD support we test the old environment variable LD_TRACE_LOADED_OBJECTS. - Before we init the GOT table of the dynamic loader we have to check, if we have a DT_PLTGOT entry. If DT_PLTGOT was zero we patch somthing in the header of the dynamic loader. This was the cause, why we have to enable the DO_MPROTECT_HACKS option for all targets, to avoid segment faults. In readelflib1.c I added a warning, if we try to load a shared library, which wasn't compiled with -fPIC or -fpic. So if we disable the DO_MPROTECT_HACKS option we are sure, that we don't waste memory by shared libraries which aren't able to share their text segment. I think this is a helpful option on little embedded systems.

look into what is breaking dlclose() further... -Erik
2002-11-15This draws from an old patch by David Blythe for the now-deadEric Andersen
unified syscall interface. I reworked his old patch considerably and cleaned up his version of bits/syscalls.h with some sneaky macro magic. And I implemented a powerpc correct version of pread/pwrite -Erik

I attached a patch, which revise the clone.S and vfork.S: - Use PIC code. - include new file syscall.S, so we can simply make a branch to __syscall_error instead of a PLT/GOT call - call errno_location to store the syscall error (for pthreads) - avoid to use the 'shad' statement on SH2 targets - call fork if vfork isn't available - some cleanups and optimization

Hi Erik, I added the FPU support for the setjmp/longjmp stuff. This patch also moves the code from the bsd*.S files to the setjmp.S file, so we can use simple branch instructions instead of referencing over the .GOT/.PLT section. This makes the PIC code much easier, smaller and faster. (The idea comes from the SPARC target) Bye Stefan

2002-11-15Ronald Wahl writes:Eric Andersen
since uclibc-0.9.16 I have to specify -fpic during _link_-time or else I get an error from the dynamic linker when I load shared objects. Patch is appended.
2002-11-15Ronald Wahl writes:Eric Andersen
I noticed that dlclose() does not work since libraries loaded with dlopen are not marked as "loaded_file". This breaks apache with dynamic modules. I append a small fix against uClibc-0.9.16.
2002-11-15I was an idiot and put _fini into the wrong register. Duh.Eric Andersen
This patch from David Meggy fixes it...

2002-11-12A powerpc patch from Ronald Wahl:Eric Andersen
Ok, now i got it after a day of work. I have had a look into glibc and found the following: sysdeps/powerpc/dl-machine.c: ... case R_PPC_JMP_SLOT: /* It used to be that elf_machine_fixup_plt was used here, but that doesn't work when ld.so relocates itself for the second time. On the bright side, there's no need to worry about thread-safety here. */ { Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr; ... The comment made me suspicious. The same position in uClibc looks like this: ldso/ldso/powerpc/elfinterp.c: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = (unsigned long)_dl_linux_resolve; int delta = targ_addr - (unsigned long)reloc_addr; ... When I change it to the following it works: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = *reloc_addr; int delta = targ_addr - (unsigned long)reloc_addr; ... I hope it will not break anything. Can anyone review this change and commit it into CVS? thanks, ron

2002-11-08Patch from Stefan Allius for libgcc multilib supportEric Andersen
this is the last patch, we need to make the support of multitarget libgcc complete. --------------------------------- In ldso/ldso/Makefile I added the CPU_LDFLAGS-y to the LDFLAGS --------------------------------- In libc/Makefile I set the LDFLAGS for the script get-needed-objects.sh with CPU_LDFLAGS-y --------------------------------- In extra/scripts/get-needed-object.sh we now use the LIBGCC from Rules.mak and call LD with LDFLAGS (==CPU_LDFLAGS-y). Addtionally I grep the NM output, to fix the unresolved external __GLOBAL_OFFSET_TABLE__ on SuperH targets. ---------------------------------
