bit_size_type - a data type?

[Mohamed Shafi]

Hello all,

During debugging in gimple dumps i found a term that is used along
with other data types - bit_size_type.

I am getting ICEs when size of int is 32 bit and no errors when the
size of int is 16. This is for a back-end whose native size is 16bit.

Is this any internal data type used to for representation?
What is the size of this data type? Will i be able to control the size
of this like we can for other data types?

Regards,
Shafi
