From 409fb368a9e6a2f35003d636aa2eea6456e56f53 Mon Sep 17 00:00:00 2001 From: Lang Hames Date: Thu, 5 Apr 2018 21:56:55 +0000 Subject: [PATCH] [RuntimeDyld][PowerPC] Add a test case for r329335. Checks that calls to different sections go to the function's global entry point, rather than the local one. llvm-svn: 329355 --- .../PowerPC/Inputs/ppc64_elf_module_b.s | 42 +++++++++++++++++++ .../RuntimeDyld/PowerPC/ppc64_elf.s | 47 ++++++++++++++++++++++ 2 files changed, 89 insertions(+) create mode 100644 llvm/test/ExecutionEngine/RuntimeDyld/PowerPC/Inputs/ppc64_elf_module_b.s create mode 100644 llvm/test/ExecutionEngine/RuntimeDyld/PowerPC/ppc64_elf.s diff --git a/llvm/test/ExecutionEngine/RuntimeDyld/PowerPC/Inputs/ppc64_elf_module_b.s b/llvm/test/ExecutionEngine/RuntimeDyld/PowerPC/Inputs/ppc64_elf_module_b.s new file mode 100644 index 0000000..f47ddbd --- /dev/null +++ b/llvm/test/ExecutionEngine/RuntimeDyld/PowerPC/Inputs/ppc64_elf_module_b.s @@ -0,0 +1,42 @@ +# This module contains a function with its local and global entry points +# exposed.
