Slava Pestov	5680bfde55	IRGen: Always use YAML files for completely fragile class layout ... The layouts of resilient value types shipped in the Swift 5 standard library x and overlays will forever be frozen in time for backward deployment to old Objective-C runtimes. This PR ensures that even if the layouts of these types evolve in the future, binaries built to run on the old runtime will continue to lay out class instances in a manner compatible with Swift 5.

Saleem Abdulrasool	8f2f097328	Frontend: address some late comments from Jordan ... Move the option definition into FrontendOptions.td as it no longer can be passed to the driver. Use the single-dash separate form for the argument which is more uniform with the rest of the options (and is arguably aesthetically more pleasing). NFC.	2016-07-06 21:35:57 -07:00
Saleem Abdulrasool	53b9eb46ed	Frontend: add -autolink-library= option to support Windows ... All modules on Windows need to link against one of {libcmtd.lib, libcmt.lib, msvcrtd.lib, msvcrt.lib}. In addition to being the C library, it is the equivalent of crtbegin0.o on other targets. It is responsible for providing the entry point itself. Traditionally, cl will embed the linkage requirement into all objects based on the flags given -- one of {/MTd, /MT, /MDd, /MD}. clang emulates this via the `--dependent-lib=` option. Emulate that behaviour in the swift driver so that swift objects being compiled for Windows targets can auto-link to the required libraries.	2016-07-06 17:53:04 -07:00
