Cherry Zhang 89bf297b24 cmd/internal/objfile: emit better error for Go object of a different version ... The Go object file format can change from version to version. Tools like cmd/objdump and cmd/nm only onderstand the current version of the object file. Currently, when it encounters an object built with a different version of the toolchain, it emits a generic error "unrecognized object file", which is not very helpful for users. This CL makes it emit a clearer error. Now it emits objdump: open go116.o: go object of a different version: go116ld Change-Id: I063c6078ed1da78f97cea65796779ae093a1a8cb Reviewed-on: https://go-review.googlesource.com/c/go/+/315609 Trust: Cherry Zhang <cherryyz@google.com> Run-TryBot: Cherry Zhang <cherryyz@google.com> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Than McIntosh <thanm@google.com>		2021-04-30 16:53:35 +00:00
