--- Comment #5 from Nick Clifton <nickc at redhat dot com> --- (In reply to Guillermo E.

Basically the idea is, (I think...), we define a new section flag, eg: SHF_GNU_CAN_BE_STRIPPED which would be set by the linker on any section that it believes is not necessary for proper execution of the binary. (ie debug info sections, notes that are not needed by the loader, etc). In addition tools like objcopy should be able to add or remove this flag from specific sections at the behest of the user. The purpose of the flag is to tell tools like strip and eu-strip that the section can and should be removed or preserved when stripping or creating a debuginfo file. (At the moment this decision is made by heuristics built into these tools, and the heuristics differ...) In order to support backwards compatibility with files that do not use this scheme, it will probably also be necessary to define a second flag: SHF_GNU_DO_NOT_STRIP Then the tools can detect sections which have not been annotated with this new feature and fall back on their old heuristics instead. ------------------------------------------------------------------------- Does that sound about right ? If so then I think that the proper way to proceed with this idea is to present it on the GNU gABI list (gnu-g...@sourceware.org) rather than discussing it inside a binutils PR. Do you agree ?
