Niko Matsakis	9e3d0b002a	librustc: Remove the fallback to int from typechecking. ... This breaks a fair amount of code. The typical patterns are: * `for _ in range(0, 10)`: change to `for _ in range(0u, 10)`; * `println!("{}", 3)`: change to `println!("{}", 3i)`; * `[1, 2, 3].len()`: change to `[1i, 2, 3].len()`. RFC #30. Closes #6023. [breaking-change]	2014-06-24 17:18:48 -07:00
Edward Wang	90449abcb3	Adjust codegen logic for range and guarded arms ... By carefully distinguishing falling back to the default arm from moving on to the next pattern, this patch adjusts the codegen logic for range and guarded arms of pattern matching expression. It is a more appropriate way of fixing #12582 and #13027 without causing regressions such as #13867. Closes #13867	2014-05-05 20:17:59 +08:00
