- 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 Change-Id: If66a7157f46b5b66230ef91e15826b910cf979a2 Reviewed-on: https://boringssl-review.googlesource.com/31364 Commit-Queue: David Benjamin <davidben@google.com> CQ-Verified: CQ bot account: commit-bot@chromium.org <commit-bot@chromium.org> Reviewed-by: David Benjamin <davidben@google.com>
