From 11f457aad3fe3ae09c1838b542e4a95541d2742f Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Wed, 10 Jan 2007 19:50:43 +0000 Subject: [PATCH] Allow LLI, in interpreter mode, to find stdin, stdout, and stderr. This is a bit of a hack but it lets some of the llvm-test programs run. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33058 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/System/DynamicLibrary.cpp | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/lib/System/DynamicLibrary.cpp b/lib/System/DynamicLibrary.cpp index 0876d5deecd..f0ab51b0f61 100644 --- a/lib/System/DynamicLibrary.cpp +++ b/lib/System/DynamicLibrary.cpp @@ -141,10 +141,11 @@ void* DynamicLibrary::SearchForAddressOfSymbol(const char* symbolName) { // important symbols are marked 'private external' which doesn't allow // SearchForAddressOfSymbol to find them.
