From c0974a1344f0c565f0200d28537806bf07b68acf Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 8 Jan 2007 07:36:34 +0000 Subject: fix atexit. This is an overcomplex way of calling exit, but it is required, as the jit intercepts exit calls to implement atexit handlers. This fixes SingleSource/UnitTests/2003-05-14-AtExit git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33008 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/lli/lli.cpp | 19 ++++++++++++++++--- 1 file changed, 16 insertions(+), 3 deletions(-) diff --git a/tools/lli/lli.cpp b/tools/lli/lli.cpp index 998e761681..9f1ecc2978 100644 --- a/tools/lli/lli.cpp +++ b/tools/lli/lli.cpp @@ -118,9 +118,22 @@ int main(int argc, char **argv, char * const *envp) { // Run static destructors.
