Author: David Blaikie Date: 2021-09-13T19:17:05-07:00 New Revision: 2bd84938470bf2e337801faafb8a67710f46429d
URL: https://github.com/llvm/llvm-project/commit/2bd84938470bf2e337801faafb8a67710f46429d DIFF: https://github.com/llvm/llvm-project/commit/2bd84938470bf2e337801faafb8a67710f46429d.diff LOG: Improve type printing of const arrays to normalize array-of-const and const-array Since these map to the same effective type - render them the same/in the more legible way (const x[n]).
