annotate lwasm/insn_gen.c @ 458:3948c874901b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make offset,R operand size warning work properly Make the offset,R operand size check warning work for non-lea operations. Also exclude offset,W from the check since there is no 8 bit offset.
