Normally META_MODE ignores host files for "meta mode" decisions on whether a file should be rebuilt or not. This is because a simple installworld can update timestamps and cause the next build to rebuild all host tools, when the previous ones may not have any changes in the source tree. These tools are normally still ABI compatible. They are only rebuilt if NO_META_IGNORE_HOST is set from the workaround/hack in r301467. One of the major problems with this is when a host tool has objects spread across many revisions that have mixed-ABI. For example, if struct stat were to change on the host, some objects for a tool may have different ideas of that struct's definition. If just 1 source file were modified and rebuilt and linked into the tool, then that toll will have mixed-ABI objects and crash. This exact thing happened with the ino64 commit in r301467 followed by a trivial update to libbfd in r318750. The resulting binary would crash in buildworld. Sponsored by: Dell EMC Isilon |
