3000 5884 d 4 h svoboda /branches/dynload/uspace/lib/rtld/ Implement BFS for looking-up symbols. Add support for DT_SYMBOLIC flag. Set soname when building rtld.so. Strip path components when comparing module names.  
2999 5884 d 22 h svoboda /branches/dynload/uspace/lib/rtld/ Load all requested libraries recursively and construct a module dependency graph -- work towards supporting arbitrary deps. (incomplete)  
2998 5885 d 0 h svoboda /branches/dynload/uspace/lib/rtld/ Function for finding the address of a symbol. Use ELF hash table in def_find_in_module()  
2997 5885 d 3 h svoboda /branches/dynload/uspace/lib/rtld/ Fix ppc32 PLT. dltest now says hello on ppc32, too.  
2996 5885 d 16 h svoboda /branches/dynload/ Improve ppc32 dynamic loading support. Getting there...  
2995 5885 d 18 h svoboda /branches/dynload/uspace/lib/rtld/arch/ Initial ppc32 support in rtld. (bootstrap only)  
2990 5886 d 19 h svoboda /branches/dynload/uspace/ Add function inline function __pcb_get() for getting PCB address  
2989 5886 d 20 h svoboda /branches/dynload/uspace/ Simplify rtld bootstrap by passing its bias and dynamic section pointer in PCB  
2985 5886 d 23 h svoboda /branches/dynload/ Fix as_area_change_flags() and use it in elf_loader.c  
2984 5887 d 0 h svoboda /branches/dynload/ Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.  
2983 5887 d 3 h svoboda /branches/dynload/uspace/ Remove TLS sections from dltest. Do not add bias to absolute symbols (_tls_alignment). dltest now says hello.  
2982 5887 d 16 h svoboda /branches/dynload/uspace/ Link dltest with libc.so. Runs, but no console output.  
2981 5887 d 17 h svoboda /branches/dynload/uspace/lib/rtld/ Let rtld analyze its own dynamic section. Search for symbols in all rtld, program, lib. Resolve references in library, too.  
2980 5887 d 18 h svoboda /branches/dynload/uspace/lib/rtld/ Fix handling of absent soname and rpath fields in .dynamic section. Slightly improve symbol search.  
2979 5887 d 22 h svoboda /branches/dynload/uspace/ Build shared C library  
2978 5887 d 22 h svoboda /branches/dynload/uspace/ Trivially link unresolved references from dltest to libtest  
2975 5888 d 22 h svoboda /branches/dynload/uspace/lib/rtld/ Remove obsolete code fragments  
2973 5888 d 22 h svoboda /branches/dynload/uspace/ Parse program's relocation table  
2972 5889 d 0 h svoboda /branches/dynload/uspace/ Add so_bias argument to elf_load_file(). Successfully load libtest.so into memory.  
2971 5889 d 0 h svoboda /branches/dynload/uspace/ Add libtest to iramfs. Link rtld with position-independent libsoftfloat.  
2970 5889 d 1 h svoboda /branches/dynload/uspace/lib/libtest/ Fix symlink  
2969 5889 d 16 h svoboda /branches/dynload/uspace/ Incorporate ELF loader from iloader to rtld  
2968 5889 d 17 h svoboda /branches/dynload/uspace/ Parse .dynamic section fields into a more useful form.  
2967 5889 d 21 h svoboda /branches/dynload/uspace/ For testing purposes, add a trivial shared library and a program linked to it  
2966 5890 d 0 h svoboda /branches/dynload/uspace/lib/rtld/ Define more ELF constants and use them  
2965 5890 d 0 h svoboda /branches/dynload/uspace/ Add headers for dynamic-loading-related ELF stuff. Reorganize rtld include directories.  
2959 5890 d 3 h svoboda /branches/dynload/ Load both program and dynamic linker from program loader. Pass program entry point to dynamic linker and have it run the program  
2956 5890 d 17 h svoboda /branches/dynload/uspace/lib/ Temporarily force local dynamic TLS model in libc by declaring all __thread variables static. Implement a trivial __tls_get_addr() function. Now rtld works linked with libc. Yaay! :D  
2955 5891 d 0 h svoboda /branches/dynload/ Build a position-independent libc  
2954 5891 d 2 h svoboda /branches/dynload/uspace/lib/rtld/ Read a file from rtld with more ugly hacking  
2952 5891 d 17 h svoboda /branches/dynload/ Load rtld.so with iloader and make it write to console with a stripped-down version of the C library  
2950 5891 d 17 h svoboda /branches/dynload/uspace/lib/rtld/arch/ia32/ Fix rtld linker script with some magic so that ld produces correct DT_REL[SZ], DT_JMPREL, DT_PLTRELSZ entries  
2933 5893 d 22 h svoboda /branches/dynload/uspace/ Add library rtld, the future run-time dynamic linker  
2927 5894 d 3 h decky /branches/dynload/ added dynload branch  
2879 5904 d 22 h jermar /trunk/uspace/lib/libc/include/libadt/ Add functions for inserting items before or after other items in a boubly-linked
circular lists.		  
2863 5919 d 2 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2861 5922 d 17 h cejka /trunk/ Used common macro for context saving on ppc64.  
2860 5923 d 17 h cejka /trunk/ Context handling unified for sparc64.  
2858 5924 d 10 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5924 d 10 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.
