Int64 functions?

[ghost]

Here is new ARB int64 functions.

Also AMD have:
https://khronos.org/registry/OpenGL/extensions/AMD/AMD_gpu_shader_int16.txt
https://khronos.org/registry/OpenGL/extensions/AMD/AMD_gpu_shader_half_float.txt

I want to propose to add packing functions, and operations for int64 vectors and numbers.

Sounds like a great idea!

Add:
| Returns an unsigned 32- or 64-bit integer obtained |
| int packInt2x16 (i16vec2 v) | by packing the components of a two- or |
| int64_t packInt4x16 (i16vec4 v) | four-component 16-bit signed or unsigned integer |
| uint packUint2x16(u16vec2 v) | vector, respectively. The first vector component |
| uint64_t packUint4x16(u16vec4 v) | specifies the 16 least significant bits; the |
| | last component specifies the 16 most significant |
| | bits. |
+-----------------------------------+------------------------------------------------------+
| | Returns a signed or unsigned integer vector built |
| i16vec2 unpackInt2x16 (int v)| from a 32- or 64-bit signed or unsigned integer |
| i16vec4 unpackInt4x16 (int64_t v)| scalar, respectively. The first component of the |
| u16vec2 unpackUint2x16(uint v)| vector contains the 16 least significant bits of the |
| u16vec4 unpackUint4x16(uint64_t v)| input; the last component specifies the 16 most |
| | significant bits. |

This issue is fixed in master branch for GLM 0.9.9 release.

I added also packing function for all primitive integer types.

Thanks,

Have in CUDA support?
