[PATCH 00/12] newlib: RISC-V: Optimize memory and string functions for code size

[m fally]

This patch series optimizes the size-optimized versions of
memset(), memcpy(), memmove(), and strcmp() for the RISC-V port.
The majority of instructions in each function will now be compressed
when compiled with the C and (optionally) Zcb extensions.

This is the second patch series that is part of a three-month
mentorship to optimize de RISC-V port for speed and size.
