This directory holds the core of the BoringCrypto implementation
as well as the build scripts for the module itself: syso/*.syso.

syso/goboringcrypto_linux_amd64.syso is built with:

	GOARCH=amd64 ./build.sh

syso/goboringcrypto_linux_arm64.syso is built with:

	GOARCH=arm64 ./build.sh

Both run on an x86 Debian Linux system using Docker.
For the arm64 build to run on an x86 system, you need

objcopy --redefine-syms=renames.txt goboringcrypto1.o goboringcrypto2.o
objcopy --keep-global-symbols=globals.txt --strip-unneeded goboringcrypto2.o goboringcrypto_linux_$GOARCH.syso

# Done!

// This header file describes the BoringCrypto ABI as built for use in Go.
// The BoringCrypto build for Go (which generates goboringcrypto_*.syso)
// takes the standard libcrypto.a from BoringCrypto and adds the prefix
// _goboringcrypto_ to every symbol, to avoid possible conflicts with
// code wrapping a different BoringCrypto or OpenSSL.
