The following JSC stress test failures have been introduced recently: jsc-layout-tests.yaml/js/script-tests/dfg-osr-entry-hoisted-clobbered-structure-check.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/regress-141098.js.layout-no-llint I saw this when I tested with r192767.

With r196590, the following tests are also now failing: jsc-layout-tests.yaml/js/script-tests/dfg-float32array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-float64array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-int16array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-int32array-overflow-values.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-int32array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-int8array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-uint16array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-uint32array-overflow-values.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-uint32array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-uint8array.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-uint8clampedarray.js.layout-no-llint All of these tests are failing on the no LLINT configuration.

AFAICT, these tests are only failing because they are compiling too much with the LLINT disabled. As a result, they are using more JIT code heap space than is allowed by the OS. I'm looking into excluding these tests on the noLLINT configuration on ARMv7.

I've verified that this patch only excludes the noLLInt configuration on 32-bit arm. It still runs that configuration on arm64.
