From 9a2402566102dd54c66f55a62da93e1c7d93f761 Mon Sep 17 00:00:00 2001 From: Richard Diamond Date: Tue, 15 Sep 2015 16:22:16 -0500 Subject: Avoid loading the whole gdb debug scripts section. This is so LLVM isn't forced to load every byte of it. Also sets the alignment of the load. Adds a test for the debug script section. --- src/test/codegen/gdb_debug_script_load.rs | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 src/test/codegen/gdb_debug_script_load.rs (limited to 'src/test/codegen/gdb_debug_script_load.rs') diff --git a/src/test/codegen/gdb_debug_script_load.rs b/src/test/codegen/gdb_debug_script_load.rs new file mode 100644 index 00000000000..efaca29752b --- /dev/null +++ b/src/test/codegen/gdb_debug_script_load.rs @@ -0,0 +1,25 @@ +// Copyright 2015 The Rust Project Developers.
