Changes
Summary
- [llvm-pdbdump] Abstract some of the YAML/Raw printing code. There is a lot of duplicate code for printing line info between YAML and the raw output printer. This introduces a base class that can be shared between the two, and makes some minor cleanups in the process.
- PR26771: don't forget the " 2" (returning from #included file) linemarker after including an empty file with -frewrite-includes.
- Remove unused, empty test directories.
- Add pragma to perform module import and use it in -E output. Many of our supported configurations support modules but do not have any first-class syntax to perform a module import. This leaves us with a problem: there is no way to represent the expansion of a #include that imports a module in the -E output for such languages. (We don't want to just leave it as a #include because that requires the consumer of the preprocessed source to have the same file system layout and include paths as the creator.) This patch adds a new pragma: #pragma clang module import MODULE.NAME.HERE that imports a module, and changes -E and -frewrite-includes to use it when rewriting a #include that maps to a module import. We don't make any attempt to use a native language syntax import if one exists, to get more consistent output. (If in the future, @import and #include have different semantics in some way, the pragma will track the #include semantics.)
- [ObjCARC] Do not move a release between a call and a retainAutoreleasedReturnValue that retains the returned value. This commit fixes a bug in ARC optimizer where it moves a release between a call and a retainAutoreleasedReturnValue, causing the returned object to be released before the retainAutoreleasedReturnValue can retain it. This commit accomplishes that by doing a lookahead and checking whether the call prevents the release from moving upwards. In the long term, we should treat the region between the retainAutoreleasedReturnValue and the call as a critical section and disallow moving anything there (possibly using operand bundles). rdar://problem/20449878
- [LoopUnswitch] Make DEBUG output more readable (part 2). I fixed my miscompile in r301722 and I hope I don't have to take a look at this code again now that Chandler has a new LoopUnswitch pass, but maybe this could be of use for somebody else in the meanwhile.
