- In base.h, if BORINGSSL_PREFIX is defined, include
boringssl_prefix_symbols.h
- In all .S files, if BORINGSSL_PREFIX is defined, include
boringssl_prefix_symbols_asm.h
- In base.h, BSSL_NAMESPACE_BEGIN and BSSL_NAMESPACE_END are
defined with appropriate values depending on whether
BORINGSSL_PREFIX is defined; these macros are used in place
of 'namespace bssl {' and '}'
- Add util/make_prefix_headers.go, which takes a list of symbols
and auto-generates the header files mentioned above
- In CMakeLists.txt, if BORINGSSL_PREFIX and BORINGSSL_PREFIX_SYMBOLS
are defined, run util/make_prefix_headers.go to generate header
files
- In various CMakeLists.txt files, add "global_target" that all
targets depend on to give us a place to hook logic that must run
before all other targets (in particular, the header file generation
logic)
- Document this in BUILDING.md, including the fact that it is
the caller's responsibility to provide the symbol list and keep it
up to date
- Note that this scheme has not been tested on Windows, and likely
does not work on it; Windows support will need to be added in a
future commit
