syntax: functions require return type. remove `->` The purpose of this is: * Only one way to do things * Changing a function with void return type to return a possible error becomes a 1 character change, subtly encouraging people to use errors. See #632 Here are some imperfect sed commands for performing this update: remove arrow: ``` sed -i 's/\(\bfn\b.\)-> /\1/g' $(find . -name ".zig") ``` add void: ``` sed -i 's/\(\bfn\b.\))\s{/\1) void {/g' $(find ../ -name "*.zig") ``` Some cleanup may be necessary, but this should do the bulk of the work. 2018-01-25 09:10:11 +00:00			`pub extern fn __udivti3(a: u128, b: u128) u128 {`

compiler-rt: better way to do the ABI required on Windows This removes the compiler_rt.setXmm0 hack. Instead, for the functions that use i128 or u128 in their parameter and return types, we use `@Vector(2, u64)` which generates the LLVM IR `<2 x i64>` type that matches what Clang generates for `typedef int ti_int __attribute__ ((mode (TI)))` when targeting Windows x86_64. 2019-04-10 23:47:14 +01:00			`const v128 = @Vector(2, u64);`
