- Create separate swift_begin.o/swift_end.o for lib/swift and
lib/swift_static. The static swift_begin.o does not call
swift_addNewDSOImage() at startup.
- Update ToolChains.cpp to use the correct swift_begin.o/swift_end.o
files for the `-static-stdlib` and `-static-executable` options.
- For ELF targets, keep track of shared objects as they are
dynamically loaded so that section data can be added to
the protocol conformance and type metadata caches after
initialisation (rdar://problem/19045112).
- Revert the use of SWIFT_RUNTIME_EXPORT in ImageInspectionELF.cpp and
fix the unittests by explicitly adding the file to the list
- Revert the change of section data names
- Add ImageInspectionStatic.cpp to lookup protocol conformance
and metadata sections in static binaries
- For Linux, build libswiftImageInspectionShared.a and
libswiftImageInspectionStatic.a for linking with libswiftCore.a.
This allows static binaries to be built without linking to
libdl. libswiftImageInspectionShared (ImageInspectionELF.cpp) is
automatically compiled into libswiftCore.so
- Adds -static-executable option to swiftc to use along with
-emit-executable that uses linker arguments in
static-executable-args.lnk. This also requires a libicu
to be compiled using the --libicu which has configure options
that dont require libdl for accessing ICU datafiles
- Static binaries only work on Linux at this time
