From 4bad07fbec9d42769fdc5cea891f8cb7a3b284d5 Mon Sep 17 00:00:00 2001 From: Andrew Kaylor Date: Fri, 11 Oct 2013 22:47:10 +0000 Subject: Fixing problems in lli's RemoteMemoryManager. This fixes a problem from a previous check-in where a return value was omitted. Previously the remote/stubs-remote.ll and remote/stubs-sm-pic.ll tests were reporting passes, but they should have been failing. Those tests attempt to link against an external symbol and remote symbol resolution is not supported. The old RemoteMemoryManager implementation resulted in local symbols being used for resolution and the child process crashed but the test didn't notice. With this check-in remote symbol resolution fails, and so the test (correctly) fails. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192514 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/lli/RemoteMemoryManager.h | 2 +- tools/lli/lli.cpp | 12 ++++++------ 2 files changed, 7 insertions(+), 7 deletions(-) (limited to 'tools') diff --git a/tools/lli/RemoteMemoryManager.h b/tools/lli/RemoteMemoryManager.h index eabe042fff..16d0a808b9 100644 --- a/tools/lli/RemoteMemoryManager.h +++ b/tools/lli/RemoteMemoryManager.h @@ -78,7 +78,7 @@ public: // interface does support this, but clients must provide their own // mechanism for finding remote symbol addresses.
