Bug ID: 95389
Summary: Kubernetes build fails because of mangled PkgPath
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go

Hi,
while trying to build Kubernetes on sparc64 (yes, this is a currently
unsupported platform as far as Kubernetes is concerned), I stumbled over a
PkgPath issue. Kubernetes uses (among a multitude of others) a packages path
as:
vendor/k8s.io/code-generator/pkg/util
>From the path specifications of golang, I think that k8s.io is a legal package
part, as long as the dot is not used as first character in a path component.
gccgo is turning this into the PgkPath:
vendor/k8s.x2eio/code-generator/pkg/util
Which seems to be a result of a path mangling by the go frontend method
go_mangle_pkgpath in gcc/go/gofrontend/go-encode-id.cc, which encodes the dot
to the string ".x2e". This would be perfectly OK, if the PkgPath in golang
would be used unmangled, but the dot encoding slips through.
I admit that I didn't find the point where the dot unmangling should be
inserted, sorry.
