+Almost all of the code present in these source files was taken
+from GLIBC. In the descriptions below, all files mentioned are
+with respect to the top level GLIBC source directory accept for
+the code taken from the Linux kernel.
+
+boot1_arch.h
+------------
+Contains code to fix up the stack pointer so that the dynamic
+linker can find argc, argv and Auxillary Vector Table (AVT).
+The codes is taken from the function 'RTLD_START' in the
+file 'sysdeps/mips/dl-machine.h'.
+
+elfinterp.c
+-----------
+Contains '_dl_init_got' which initializes the GOT for the
+application being dynamically linked and loaded. The code is
+taken from the functions 'elf_machine_runtime_setup' and 
+'elf_machine_got_rel' in the file 'sysdeps/mips/dl-machine.h'.
+
+ld_syscalls.h
+-------------
+Contains all the macro function prototypes for the system calls
+as well as the list of system calls supported. The macros were
+taken from the Linux kernel source 2.4.17 found in the file
+'include/asm-mips/unistd.h'.
+
+ld_sysdep.h
+-----------
+Contains bootstrap code for the dynamic linker, magic numbers
+for detecting MIPS target types and some macros. The macro
+function 'PERFORM_BOOTSTRAP_GOT' is used to relocate the dynamic
+linker's GOT so that function calls can be made. The code is
+taken from the function 'ELF_MACHINE_BEFORE_RTLD_RELOC' in the
+file 'sysdep/mips/dl-machine.h'. The other macro function
+'PERFORM_BOOTSTRAP_RELOC' is used to do the relocations for
+the dynamic loader. The code is taken from the function
+'elf_machine_rel' in the file 'sysdep/mips/dl-machine.h'.
+
+resolve.S
+---------
+Contains the low-level assembly code for the dynamic runtime
+resolver. The code is taken from the assembly code function
+'_dl_runtime_resolve' in the file 'sysdesp/mips/dl-machine.h'.
