Bug 7414 – Vector literal assignment doesn't work in global scope

This causes the same error with or without 'immutable', but works fine within functions. // create some global constants private { immutable ulong2 signMask2 = 0x8000_0000_0000_0000; immutable uint4 signMask4 = 0x8000_0000; immutable ushort8 signMask8 = 0x8000; immutable ubyte16 signMask16 = 0x80; } $ /opt/gdc/bin/gdc test.d -O2 -S -msse2 test.d:101: Error: non-constant expression cast(immutable(__vector(ulong[2u])))9223372036854775808LU test.d:102: Error: non-constant expression cast(immutable(__vector(uint[4u])))-2147483648u test.d:103: Error: non-constant expression cast(immutable(__vector(ushort[8u])))32768 test.d:104: Error: non-constant expression cast(immutable(__vector(ubyte[16u])))128
