Andrew Kelley	58dc2b719c	better coroutine codegen, now passing first coro test ... we have to use the Suspend block with llvm.coro.end to return from the coro	2018-02-28 18:22:43 -05:00
Andrew Kelley	ad2a29ccf2	break the data dependencies that llvm coro transforms cant handle ... my simple coro test program builds now see #727	2018-02-28 16:47:13 -05:00
Andrew Kelley	026aebf2ea	another workaround for llvm coroutines ... this one doesn't work either	2018-02-28 04:01:22 -05:00
Andrew Kelley	138d6f9093	revert workaround for alloc and free as coro params ... reverts 4ac6c4d6bfb8f7ada2799ddb5ce3a9797be0518d the workaround didn't work	2018-02-27 17:46:13 -05:00
Andrew Kelley	4e43bde924	workaround for llvm: delete coroutine allocation elision ... maybe this can be reverted, but it seems to be related to llvm's coro transformations crashing. See #727	2018-02-26 21:31:00 -05:00
Andrew Kelley	4ac6c4d6bf	workaround llvm coro transformations ... by making alloc and free functions be parameters to async functions instead of using getelementptr in the DynAlloc block See #727	2018-02-26 21:14:15 -05:00
Ben Noordhuis	9aa65c0e8e	allow implicit cast from &const to ?&const &const ... Allow implicit casts from n-th degree const pointers to nullable const pointers of degree n+1. That is: fn f() void { const s = S {}; const p = &s; g(p); // Works. g(&p); // So does this. } fn g(_: ?&const &const S) void { // Nullable 2nd degree const ptr. } Fixes #731 some more.	2018-02-26 19:56:26 +01:00

Andrew Kelley	05bf666eb6	codegen for calling an async function ... See #727	2018-02-25 02:47:31 -05:00
Andrew Kelley	40dbcd09da	fix type_is_codegen_pointer being used incorrectly ... The names of these functions should probably change, but at least the semantics are correct now: * type_is_codegen_pointer - the type is either a fn, ptr, or promise * get_codegen_ptr_type - - ?&T and &T returns &T - ?promise and promise returns promise - ?fn()void and fn()void returns fn()void - otherwise returns nullptr	2018-02-23 12:49:21 -05:00
Ben Noordhuis	f11b948019	allow implicit cast from S to ?&const S ... Allow implicit casts from container types to nullable const pointers to said container type. That is: fn f() void { const s = S {}; g(s); // Works. g(&s); // So does this. } fn g(_: ?&const S) void { // Nullable const pointer. } Fixes #731.	2018-02-23 15:55:57 +01:00
Andrew Kelley	99985ad6fc	implement Zig IR for async functions ... See #727	2018-02-23 03:03:06 -05:00
Ben Noordhuis	0845cbe277	name types inside functions after variable ... Before this commit: fn f() []const u8 { const S = struct {}; return @typeName(S); // "f()", unexpected. } And now: fn f() []const u8 { const S = struct {}; return @typeName(S); // "S", expected. } Fixes #675.	2018-02-22 19:54:02 +01:00
