[PATCH] D128144: [AArch64] Known bits for AArch64ISD::DUP

[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo added a comment.

This breaks compilation for me, causing hangs when compiling some source files. Repro with https://martin.st/temp/rdopt-preproc.c, built with `clang -target aarch64-w64-mingw32 -w -c -O3 rdopt-preproc.c`. Previously this completed in ~5 seconds, now it doesn't terminate.
