Hello Richard, The patch you sent in rust-common.bbclass fixing the ' oe-selftest -r sstatetests.SStateTests.test_sstate_allarch_samesigs' test issue but the regression test shows that the 'sstatetests.SStateTests.test_sstate_32_64_same_hash' is getting failed. So, I think this change is not correct. With this patch, the diffsigs shows 'rust-native' sigdata is changed based on the changed value for RUST_TARGET_SYS variable (in x86_64 :: x86_64-unknown-linux-gnu & in i686 :: i686-unknown-linux-gnu). I tried several attempts to fix it but nothing worked out yet. @Alex. Did you get sometime to look into this 'arm' issue introduced with your commit? Thanks, Sundeep K.
