v0.3.0

Added

• Toolchain and hardware support for Xpulp instructions:
  • Post-incrementing and register-register loads and stores (pv.lb[u], pv.lh[u], pv.lw)
  • 32-bit multiply-accumulate instructions (pv.mac, pv.msu)
  • Arithmetic SIMD instructions (pv.{add, sub, abs, avg, avgu, min, minu, max, maxu, srl, sra, sll, or, xor, and, dotsp, dotup, dotusp, sdotsp, sdotup, sdotusp}.{h, b}
  • Sub-word manipulation SIMD instructions (pv.{extract, extractu, insert, shuffle2}.{h, b})

Fixed

• Disable the branch prediction if there are multiple early-hits
• Align end of .text section with the instruction cache
• Observe the code style guidelines in the matrix multiplication and convolution kernels

Changed

• Clean-up the pedantic compilation warnings of the matrix multiplication and convolution kernels
