Description Iain Buclaw 2013-12-10 04:47:10 UTC 
Currently, trying to do array/vector operations in CTFE causes an ICE.

Tests:
---
enum int[4] A = [1,2,3,4];
enum int[4] B = [1,2,3,4];
// Internal Compiler Error: non-constant value [1, 2, 3, 4]
enum int[4] C = A[] + B[];

import core.simd;
enum int4 D = [1,2,3,4];
enum int4 E = [1,2,3,4];
// Internal Compiler Error: non-constant value [1, 2, 3, 4]
enum int4 F = D + E;

Add a proper error message at least:

https://github.com/dlang/dmd/pull/5706

until a fix can be devised.

ICE are gone since 2.072
Comment 7 Iain Buclaw 2019-07-11 04:51:00 UTC 
Replacing an ICE with an error is not a fix.

Updating tags from ice to rejects-valid.
Comment 8 basile-z 2019-07-11 07:05:35 UTC 
You should change the title as well. (this is why I closed : the issue was about the ICE. Change the title and it's a complete different thing)
