            Bug ID: 49962
           Summary: riscv intrinsic tests increased check-clang times by
                    over 22%
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: LLVM Codegen
          Assignee: unassignedclangbugs at nondot.org
          Reporter: nicolasweber at gmx.de

Before https://github.com/llvm/llvm-project/compare/a3bfddbb6a27...59d5b8c27b43
, check-clang took around 4.5min on this bot:
http://45.33.8.238/macm1/7223/summary.html

After, it takes around 5.4min: http://45.33.8.238/macm1/7224/summary.html

Not sure what exactly is happening, but that seems like an unacceptably large
slowdown. We should probably revert for now, since clawing back test time
regressions after the fact is very difficult.
