VM rejects tuples containing uint64 with high bit set #11084
Description
Compilation fails when tuples containing high-bit uint64 are assigned to consts. This is the case with literals and also with calculation (which is how I ran into it). It's not true of smaller integer sizes.
Example
var ok1: (uint64, array[1 .. 2, int]) = block:
var b: array[1 .. 2, int]
(0x8000_0000_0000_0000'u64, b)
var ok2: (seq[uint64], uint64) = block:
var x: seq[uint64]
x.add 0x8000_0000_0000_0000'u64
(x, 0'u64)
var ok3: (char, uint64) = block:
('.', 1'u64 + 0x7FFF_FFFF_FFFF_FFFF'u64)
const ok4: array[1, uint64] = block:
var b: array[1, uint64]
b[0] = 1'u64 + 0x7FFF_FFFF_FFFF_FFFF'u64
b
const ok5: seq[uint64] = block:
@[0x8000_0000_0000_0000'u64]
