Hi Greg, >> $ sed -i 's;scripts/dtc/dtc-lexer.l;scripts/dtc/dtc-lexer.lex.c_shipped;g' \ >> queue-{4.4,4.9,4.14}/scripts-dtc-remove-redundant-yyloc-global-declaration.patch >> If you would prefer a set of patches, let me know. > Should I just drop the patch from 4.4, 4.9, and 4.14 instead? as the original author of the patch, I am not sure why it was backported to the LTS releases (unless enablement for gcc 10.x or other new toolchains is a requirement, which I'm not aware of). However I think the sed above on the *patch* means that the patch will *only* modify the generated sources, not the input sources. I think it would be better to patch both *input* and *generated* sources, or backport the generate-at-runtime patch as well (which might be even further outside the stable policy). Not knowing why it was backported, I would suggest to just dequeue the patch from the older trees. Greetings, Dirk
