The FSMs that drive the encryption logic are not performance critical, but they are very large. Build BearSSL using -Os on them, leaving -O2 everywhere else (i.e. encryption) for speed. Saves 1-2KB of flash for SSL applications.
Updating SDK libraries
- Copy .a files from SDK
libdirectory to this directory - Run
fix_sdk_libs.sh
Updating libstdc++
After building gcc using crosstool-NG, get compiled libstdc++ and remove some objects:
xtensa-lx106-elf-ar d libstdc++.a pure.o
xtensa-lx106-elf-ar d libstdc++.a vterminate.o
xtensa-lx106-elf-ar d libstdc++.a guard.o
xtensa-lx106-elf-ar d libstdc++.a functexcept.o
xtensa-lx106-elf-ar d libstdc++.a del_op.o
xtensa-lx106-elf-ar d libstdc++.a del_opv.o
xtensa-lx106-elf-ar d libstdc++.a new_op.o
xtensa-lx106-elf-ar d libstdc++.a new_opv.o
