Bug ID: 77910
Summary: [7 Regression] go: open zversion.go: no such file or
directory
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: trippels at gcc dot gnu.org
CC: cmang at google dot com
Target Milestone: ---
I cannot use "go build" anymore on trunk, e.g.:
markus@x4 demangle % go build -gccgoflags "-O2" -x c++filt.go
WORK=/tmp/go-build321763336
go: open zversion.go: no such file or directory
If I comment out the code in libgo/go/cmd/go/pkg.go in computeBuildID() I get:
markus@x4 demangle % go build -gccgoflags "-O2" -x c++filt.go
WORK=/tmp/go-build762259913

gcc-6 works fine.
