(Maybe on iOS too, but who knows, there is no public iOS JSC tester buildbot ...) JSCOnly ARM Thumb2 Linux bot: https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/141 (Note: These tests don't fail on the GTK ARM bot, but it's Thumb2, as far as I know.) New failures on ARM Thumb2 after r198981: stress/sink-arguments-past-invalid-check-int32-dfg.js.always-trigger-copy-phase stress/sink-arguments-past-invalid-check-int32-dfg.js.default stress/sink-arguments-past-invalid-check-int32-dfg.js.dfg-eager stress/sink-arguments-past-invalid-check-int32-dfg.js.dfg-eager-no-cjit-validate stress/sink-arguments-past-invalid-check-int32-dfg.js.dfg-maximal-flush-validate-no-cjit stress/sink-arguments-past-invalid-check-int32-dfg.js.no-cjit-validate-phases stress/sink-arguments-past-invalid-check-int32-dfg.js.no-llint stress/sink-arguments-past-invalid-check-int32.js.always-trigger-copy-phase stress/sink-arguments-past-invalid-check-int32.js.default stress/sink-arguments-past-invalid-check-int32.js.dfg-eager stress/sink-arguments-past-invalid-check-int32.js.dfg-eager-no-cjit-validate stress/sink-arguments-past-invalid-check-int32.js.dfg-maximal-flush-validate-no-cjit stress/sink-arguments-past-invalid-check-int32.js.no-cjit-validate-phases stress/sink-arguments-past-invalid-check-int32.js.no-llint stress/sink-object-past-invalid-check-int32.js.always-trigger-copy-phase stress/sink-object-past-invalid-check-int32.js.default stress/sink-object-past-invalid-check-int32.js.dfg-eager stress/sink-object-past-invalid-check-int32.js.dfg-eager-no-cjit-validate stress/sink-object-past-invalid-check-int32.js.dfg-maximal-flush-validate-no-cjit stress/sink-object-past-invalid-check-int32.js.no-cjit-validate-phases stress/sink-object-past-invalid-check-int32.js.no-llint 1180785 1 ysuzuki 2016-04-05 06:37:14 -0700 The patch is completely unrelated to stress/sink-arguments-past-invalid-check-int32-dfg.js tests. But I guessed that the incorrect build is done; sink-arguments-past-invalid-check-int32-dfg.js uses Int32 checking Intrinsic. And my patch adds new intrinsic. So the index of the Int32 checking intrinsic is changed. If the rebuild is not done correctly, we may misbehave here. To ensure that, I pressed force-rebuild button on the build-slave. And it seems that rebuilt one does not pose this problem. https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/153 Could you ensure that? 1180832 2 ossy 2016-04-05 09:32:27 -0700 It seesm it is a dup of bug155790. *** This bug has been marked as a duplicate of bug 155790 ***
