From 7db2edcb3364ef5415e992a18c02c73bba6cdd29 Mon Sep 17 00:00:00 2001 From: Baozeng Ding Date: Mon, 8 Aug 2016 21:32:48 +0800 Subject: sys/sysgen/prog: support ranged int This commit supports inclusive ranged int, like foo int32[-10~10], which will generate random integer between -10 and 10. In future we will support more than one range, like int32[0, -5~10, 50, 100~200] --- sysgen/parser.go | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'sysgen/parser.go') diff --git a/sysgen/parser.go b/sysgen/parser.go index 7d322eec4..c0feca7ac 100644 --- a/sysgen/parser.go +++ b/sysgen/parser.go @@ -1,4 +1,4 @@ -// Copyright 2015 syzkaller project authors.
