From 2ed4b5488f68c63da0713dc008ba8b688a742386 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Mon, 27 Jan 2014 17:32:33 +0800 Subject: Replace -1 with TARGET_XFER_E_IO Hi, This patch replaces -1 with TARGET_XFER_E_IO in the implementations of to_xfer_partial and their callees. This change is quite mechanical, and makes the next patch shorter. gdb: 2014-02-07 Yao Qi * auxv.c (procfs_xfer_auxv): Replace -1 with TARGET_XFER_E_IO.
