The following two tests are constantly failing on iOS simulator when the host Mac architecture is x86_64:

webgl/1.0.x/conformance/glsl/bugs/sampler-array-using-loop-index.html
webgl/2.0.y/conformance/glsl/bugs/sampler-array-using-loop-index.html

HISTORY (it appears passing because none of our infra tests on x86_64):

https://results.webkit.org/?platform=ios&suite=layout-tests&suite=layout-tests&test=webgl%2F1.0.x%2Fconformance%2Fglsl%2Fbugs%2Fsampler-array-using-loop-index.html&test=webgl%2F2.0.y%2Fconformance%2Fglsl%2Fbugs%2Fsampler-array-using-loop-index.html

REPRODUCIBILITY:

I was able to reproduce this issue on iOS simulator (17.5, x86_64 machine) ToT using the following command:

run-webkit-tests -v --ios-simulator webgl/1.0.x/conformance/glsl/bugs/sampler-array-using-loop-index.html webgl/2.0.y/conformance/glsl/bugs/sampler-array-using-loop-index.html
