Update the codegen/mainsubprogram tests to min-llvm 4.0 The necessary changes were only in upstream LLVM in 4.0, but they were for a while backported to Rust LLVM. Now that Rust LLVM is also 4.0, we can make the test conditional here more accurate. 2017-10-16 19:48:01 +00:00			`// This test depends on a patch that was committed to upstream LLVM`

Emit DW_AT_main_subprogram This changes rustc to emit DW_AT_main_subprogram on the "main" program. This lets gdb suitably stop at the user's main in response to "start" (rather than the library's main, which is what happens currently). Fixes #32620 r? michaelwoerister 2016-11-30 21:59:45 +00:00
