[Minios-devel] [UNIKRAFT PATCH v5 0/4] isolate symbols inside libraries

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Provide per lib/app namespaces

Changes since v1:
1) Remove --globalize-symbols (patch 1/3)
2) Complete (I hope) list of symbols needed to be exported to support
   current codebase. Except arm and linux userpace, which are brocken
   currently.
3) Update doccumentation

Changes since v2:
1) Export uk_sched_thread_sleep
2) Add option to specify per-lib suffix for export.syms

Changes since v3:
1) export.syms is renamed to exportsyms.uk in order to point out
   that this is a Unikraft-specific file
2) Output a warning whenever the exportsyms.uk file is missing but
   continue building. This way we can subsequently introduce required
   symbol files for each library afterwards and independently.
3) Give user the option to specify a alternative filename and path
   instead of just a suffix. This makes this scheme more flexible
   including supporting the case when symbol files are part of
   fetched archives from remote.
5) Add further missing symbols in symbol files
4) Removed symbol files from platform libs. They will get
   introduced separately after the long patch series for ARM
   
(https://lists.xenproject.org/archives/html/minios-devel/2018-08/msg00044.html)
   and linux userspace
   
(https://lists.xenproject.org/archives/html/minios-devel/2018-08/msg00120.html)
   are integrated.

Changes since v4:
1) Updated documentation
2) Added new symbols to exportsyms.uk of libnolibc

Simon Kuenzer (2):
  build: Introduce symbols exporting for each library
  lib/*: Add missing exportsyms.uk for libraries in `/lib`

Yuri Volchkov (2):
  doc: Add section about symbol exporting
  lib/*: Integrate existing lists of exported symbols
