# A fairly average Go build, importing some std libraries.

# We always build for a foreign GOOS.
|
|
# GOOS=windows, unless the host is also windows; then linux.
|
|
# GOARCH=arm, unless the host is also arm; then amd64.
|
|
# Windows and ARM are both interesting,
|
|
# and it helps with coverage as we mainly test on linux/amd64.
|
|
#
|
|
# We also ensure that intrinsics work as expected.
|
|
# The compiler replaces calls to some functions with intrinsics in its ssa stage,
|
|
# and it recognizes which functions via the package path and func name.
|
|
# If we obfuscate those package paths without adjusting the compiler,
|
|
# intrinsics aren't applied, causing performance loss or build errors.
|
|
# We use the math/bits package, as its Len64 intrinsic is present in both arm
|
|
# and arm64, and it is not part of the runtime nor its dependencies.
