Is there some documentation of the assembler syntax?

The assembler code uses some instructions which appear to have ABI-specific
defaults, and I can't find documentation for them, neither in the ISA
manual nor in the psABI supplement.

Chapter 20 of the RISC-V ISA spec contains an assembly writers
handbook that documents the ABI register aliases and pseudo-instructions
if that is what you are looking for.

We're also writing an assembly programmer's manual, but it's more than a little bit lacking: https://github.com/riscv/riscv-asm-manual/blob/master/riscv-asm.md
