Explicit Arithmetic Types Errors

[Karpov-Ruslan]

1. Can you add integer and float suffixes according to GL_EXT_shader_explicit_arithmetic_types extension:

   • Integer suffixes (299 line):

     Change "integer-suffix" definition:
     
      "integer-suffix:
          unsigned-suffix long-suffixopt
          unsigned-suffix short-suffixopt
          long-suffix
          short-suffix
     
       unsigned-suffix: one of
           u U
       long-suffix: one of
           l L
       short-suffix: one of
           s S"

   • Float suffixes (354 line):

     Modify the second paragraph to say:
      "floating-suffix:
           half-suffix single-suffix
           double-suffix single-suffix
           single-suffix
     
       single-suffix: one of
           f F
       half-suffix: one of
           h H
       double-suffix: one of
           L L"

   The list of additional suffixes (I use only uppercase letters, but lowercase options need to be considered):

   • L, S, UL, US for integer types.
   • HF for float types.

2. float32_t var = 1.0F; - an error occurs: "Incompatible types in initialization (and no available implicit conversion).", but float32_t var = 1.0LF; code line does not cause any errors. However, LF suffix relates to float64_t/double types.

3. Also, can you allow implicit conversion:

   • int <-> int32_t
   • uint <-> uint32_t
   • float <-> float32_t
   • double <-> float64_t

   and derivative vec cases:

   • ivecn <-> i32vecn
   • uvecn <-> u32vecn
   • vecn <-> f32vecn
   • dvecn <-> f64vecn

Hi @Karpov-Ruslan Sorry for the late replay. I'm sure about implementing extensions. I didn't get into it but it's not straightforward at all.
