Sorry not to have followed up earlier. As I said, I want fixes for trivial cases -- cases where, for instance, a macro is used in an #if which has absolutely *no* definition in the whole codebase. I do not want fixes for all cases. OTOH, to find out which failures would be trivial to fix and which ones would not, you'd have to go through all of them, which could be time-consuming, depending on the number of targets. I thus suggest we use the typical U-Boot strategy: right at the beginning of the merge period, we apply the -Wundef patch onto all repos (or on the main repo and then pulled into others) and then wait for screams. Screams should come fst from custodians, who routinely build for all targets of their assigned architecture. They will see which boards fail due to undefined macros and will report those failures on the list, copying the board maintainers (or subsystem owners if the issue is not board-specific. All boards not fixed before merge window closure release will be declared dying; all those not fixed before 2014.01 will be declared dead, and orphaned and put in the scrapyard (and then, people who want them back can always resurrect *and fix* them). Subsystems... will have to be fixed some way or other. Of course, anyone with an interest can spontaneously provide fixes for boards or subsystems affected. Adding Tom and Wolfgang for advice, but of course comments are welcome from everyone. > Best Regards, > Masahiro Yamada Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
