2.1.103 --remove_unneeded_entities, --no_remove_unneeded_entities
These options control whether debug information is generated for all source symbols,
or only for those symbols actually used.
Usage
Use --remove_unneeded_entities to reduce debug object and image file sizes. Faster
linkage times can also be achieved.
Caution
Although --remove_unneeded_entities can help to reduce the amount of debug
information generated per file, it has the disadvantage of reducing the number of debug
sections that are common to many files. This reduces the number of common debug
sections that the linker is able to remove at final link time, and can result in a final debug
image that is larger than necessary. For this reason, use --remove_unneeded_entities
only when necessary.
