Changes for v4 (thanks Jeff for your input on v3):
Deleted changes for config-ml.in. There is a patch for changing
config-ml.in on the GCC mailing list, so I will submit a request
for merging those changes into newlib if/when that patch itself
gets merged.
Deleted changes for config/mt-sde. These changes seem unecessary at
this moment.
Removed patches pertaining stdio changes and SmallLibC support.
Faraz Shahbazker (6):
libc: mips: Add improved C implementation of memcpy/memset
libc: mips: memcpy prefetches beyond copied memory
libc: mips: Improve performance of strcmp implementation
libgloss: mips: g++ exception handling failure on o32 elf targets
libgloss: mips: UHI linker scripts fail to link with _isr_vec_count=1
libc: mips: fix strcmp bug for little endian targets
Jovan Dmitrović (2):
mips: Implement MIPS HAL and UHI
libgloss: mips: Add mipshal.mk
Matthew Fortune (2):
libgloss: mips: Add srec2hex.pl for preparing input to simulators
libgloss: mips: Fixes and improvements for CM3 bootcode
Robert Suchanek (1):
libgloss: mips: Boot and startup code improvements inc. linker script
