[PATCH] D120327: compiler-rt: Add udivmodei5 to builtins and add bitint library

[Matthias Gehre via Phabricator via llvm-commits]

mgehre-amd updated this revision to Diff 418663.
mgehre-amd added a comment.

Implement a basic long division
Make it work on big endian machines
Only provide

  void __divmodei5(su_int *quo, su_int *rem, su_int *a, su_int *b,
                                 unsigned int words)

and

  void __udivmodei5(su_int *quo, su_int *rem, const su_int *a,
                                  const su_int *b, unsigned int words)

to avoid allocations.
