--- Comment #1 from Hu Lin <lin1.hu at intel dot com> --- According to the results from https://godbolt.org/z/eKnvraP8T and https://godbolt.org/z/G6MTWKf4P, certain options such as -march=armv8-m.base and -mtune=cortex-m23 influence the structure of the code in the ccp1 pass, rendering the optimization invalid in the forwprop1 pass. Since the patch is intended for general optimization, I would prefer not to impose an architecture-specific restriction for this test. Do you have any ideas for resolving this issue, or could you include this test case in the list of stable failures?
