Subject: Expose template parameters of endian specific types as class members
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c00c9f3c84398fb6c98432b99075aa25cf796a0c;p=llvm

Expose template parameters of endian specific types as class members

Summary:
This allows generic code to query these parameters, and is a common
practice in a lot of other template classes.
