Bug ID: 86331
Summary: the gccgo's "go" tool looks like failing to invoke any
sub go command
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: stephen.kim at oracle dot com
CC: cmang at google dot com
Target Milestone: ---
It seems that putting back a new version of go to gcc8 triggers the issue I
would describe here.
Invoking any go command randomly fails in aarch64:
[aion1223@localhost gcc_upstream]$ go run /home/aion1223/hello.go
hello!
[aion1223@localhost gcc_upstream]$ go run /home/aion1223/hello.go
hello!
[aion1223@localhost gcc_upstream]$ go run /home/aion1223/hello.go

Please, note that there has been no change in the hello.go.
Go run is not the only command to fail.
[aion1223@localhost gcc_upstream]$ go build -x ~/ce.go

Also, please note that the two commands issued were the same although the
output is different.
Here are some information about my system:

Basically, this is a VM running on an arm64 machine. This problem goes away if
the failed command/subtool is invoked with Google's gc's go tool with
-compiler=gccgo.
