improved behavior on debug safety crash * instead of emitting a breakpoint for a debug safety crash, zig calls a panic function which prints an error message and a stack trace and then calls abort. * on freestanding OS, this panic function has a default implementation of a simple infinite loop. * users can override the panic implementation by providing `pub fn panic(message: []const u8) -> unreachable { }` * workaround for LLVM segfaulting when you try to use cold calling convention on ARM. closes #245 2017-02-06 16:10:32 +08:00			`// This file is included if and only if the user's main source file does not`

lots of miscellaneous things all in one big commit * add `@compileLog(...)` builtin function - Helps debug code running at compile time - See #240 * fix crash when there is an error on the start value of a slice * add implicit cast from int and float types to int and float literals if the value is known at compile time * make array concatenation work with slices in addition to arrays and c string literals * fix compile error message for something not having field access * fix crash when `@setDebugSafety()` was called from a function being evaluated at compile-time * fix compile-time evaluation of overflow math builtins. * avoid debug safety panic handler in builtin.o and compiler_rt.o since we use no debug safety in these modules anyway * add compiler_rt functions for division on ARM - Closes #254 * move default panic handler to std.debug so users can call it manually * std.io.printf supports a width in the format specifier 2017-02-09 15:50:03 +08:00			`@import("std").debug.panic(message);`
