Subject: RISC-V: move comment describing rules for riscv_opcodes[]
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8d27b09d0877982dc2252c01a3f1d9c631b2d6eb;p=binutils-gdb.git

RISC-V: move comment describing rules for riscv_opcodes[]

It makes little sense to have this comment meanwhile over a hundred
lines ahead of the array. In fact until spotting the comment, I was
wondering why those pretty important aspects aren't spelled out
anywhere.
