Re: [PATCH] riscv: Add semihosting support [v4]

[Jonathan Behrens]

The text you are referencing (the couple italic paragraphs below section 2.8 in the unprivileged ISA) is non-normative and "can be skipped if the reader is only interested in the specification itself". This convention of making indented italic text non-normative is described at the bottom of page 1 of the linked document.

The RISC-V Foundation defined semihosting as relative to the existing
ARM specification, so using a link to that is appropriate here.

Here's the current specification of the unprivileged ISA, which includes
the definition of semihosting

While it may be nice in some abstract sense to create a "better"
semihosting spec, that's not what the RISC-V foundation has decided to
do.
