Artem Belevich	5d40ae3a46	Allow linking multiple bitcode files. Linking options for particular file depend on the option that specifies the file. Currently there are two: * -mlink-bitcode-file links in complete content of the specified file. * -mlink-cuda-bitcode links in only the symbols needed by current TU. Linked symbols are internalized. This bitcode linking mode is used to link device-specific bitcode provided by CUDA. Files are linked in order they are specified on command line. -mlink-cuda-bitcode replaces -fcuda-uses-libdevice flag.

Artem Belevich	ed0577cc6d	Fixed double-free in case of module loading error. GetOutputStream() owns the stream it returns pointer to and the pointer should never be freed by us. When we fail to load and exit early, unique_ptr still holds the pointer and frees it which leads to compiler crash when CompilerInstance attempts to free it again. Added regression test for failed bitcode linking. Differential Revision: http://reviews.llvm.org/D9625 llvm-svn: 237159	2015-05-12 17:44:15 +00:00
Rafael Espindola	5a1106f8fc	Make this test a bit stricter by checking clang's output too. llvm-svn: 220604	2014-10-25 01:51:19 +00:00
Stephen Lin	4362261b00	CHECK-LABEL-ify some code gen tests to improve diagnostic experience when tests fail. llvm-svn: 188447	2013-08-15 06:47:53 +00:00
Rafael Espindola	925213b0fa	Add 'not' to commands that are expected to fail. This is at least good documentation, but also opens the possibility of using pipefail. llvm-svn: 185652	2013-07-04 16:16:58 +00:00
Peter Collingbourne	f1d76db466	Add support for lazily linking bitcode files (using a new -mlink-bitcode-file flag), and more generally llvm::Modules, before running optimisations. llvm-svn: 143314	2011-10-30 17:30:44 +00:00
