--- Comment #3 from ian at gcc dot gnu.org <ian at gcc dot gnu.org> --- Author: ian Date: Tue Nov 10 20:31:11 2015 New Revision: 230120 URL: https://gcc.gnu.org/viewcvs?rev=230120&root=gcc&view=rev Log: PR go/68255 cmd/go: always use --whole-archive for gccgo packages This is a backport of https://golang.org/cl/16775. This is, in effect, what the gc toolchain does. It fixes cases where Go code refers to a C global variable; without this, if the global variable was the only thing visible in the C code, the generated cgo file might not get pulled in from the archive, leaving the Go variable uninitialized. This was reported against gccgo as https://gcc.gnu.org/PR68255 . Reviewed-on: https://go-review.googlesource.com/16778 Modified: trunk/gcc/go/gofrontend/MERGE trunk/libgo/go/cmd/go/build.go
