  "message": "[VM] Generalize generic bounds check elimination\n\nWhen eliminating bounds checks using loop information the length of\nGenericBoundsCheckInstr is directly compared to the loop bound.\n\nInstead we should compare the original definitions, ignoring any\nboxing/unboxing. This allows the elimination of more bounds checks.\n\nIssue https://github.com/dart-lang/sdk/issues/35154\n\nCq-Include-Trybots: luci.dart.try:vm-canary-linux-debug-try, vm-dartkb-linux-debug-x64-try, vm-dartkb-linux-release-x64-try, vm-kernel-asan-linux-release-x64-try, vm-kernel-checked-linux-release-x64-try, vm-kernel-linux-debug-ia32-try, vm-kernel-linux-debug-simdbc64-try, vm-kernel-linux-debug-x64-try, vm-kernel-linux-product-x64-try, vm-kernel-linux-release-ia32-try, vm-kernel-linux-release-simarm-try, vm-kernel-linux-release-simarm64-try, vm-kernel-linux-release-simdbc64-try, vm-kernel-linux-release-x64-try, vm-kernel-optcounter-threshold-linux-release-ia32-try, vm-kernel-optcounter-threshold-linux-release-x64-try, vm-kernel-precomp-android-release-arm-try, vm-kernel-precomp-bare-linux-release-simarm-try, vm-kernel-precomp-bare-linux-release-simarm64-try, vm-kernel-precomp-bare-linux-release-x64-try, vm-kernel-precomp-linux-debug-x64-try, vm-kernel-precomp-linux-product-x64-try, vm-kernel-precomp-linux-release-simarm-try, vm-kernel-precomp-linux-release-simarm64-try, vm-kernel-precomp-linux-release-x64-try, vm-kernel-precomp-obfuscate-linux-release-x64-try, vm-kernel-precomp-win-release-simarm64-try, vm-kernel-precomp-win-release-x64-try, vm-kernel-reload-linux-debug-x64-try, vm-kernel-reload-linux-release-x64-try, vm-kernel-reload-rollback-linux-debug-x64-try, vm-kernel-reload-rollback-linux-release-x64-try, vm-kernel-win-debug-ia32-try, vm-kernel-win-debug-x64-try, vm-kernel-win-product-x64-try, vm-kernel-win-release-ia32-try, vm-kernel-win-release-x64-try\nChange-Id: Ie10880f833f3b55d0804a03c4be9bd9d1ad52f66\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/97331\nCommit-Queue: Martin Kustermann \u003ckustermann@google.com\u003e\nReviewed-by: Aart Bik \u003cajcbik@google.com\u003e\nReviewed-by: Vyacheslav Egorov \u003cvegorov@google.com\u003e\n",
