digitalmars.D.bugs - [Issue 12769] New: ICE returning array


          Issue ID: 12769
           Summary: ICE returning array
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com

float[] f(float[] a)
    return -a[];

Internal error: e2ir.c 1834

DMD 2.065 w/ -m64

Here's what I was actually trying to do at the time:

float[4] f(float[4] a)
    return (-a[])[0..4];

Here's another permutation. It'd be nice if it could work out what '$' was at
compile time:

float[4] f(float[4] a)
    return (-a[])[0..$]; // use dollar instead of explicit '4'

Error: cannot implicitly convert expression ((-a[])[0..__dollar]) of type
float[] to float[4]

Ideally, this should work with static arrays:

float[4] f(float[4] a)
    return -a;

requiring a[] causes a to become a dynamic array, and then it can't be assigned
back to a static array anymore. It all goes south for array operations on
static arrays with [].
