| | | | | | | | | | | | | | | | | | | | | | | | PR go/66904 cmd/go: fix "#cgo pkg-config:" comments with gccgo Copy of https://golang.org/cl/18790 by Michael Hudson-Doyle. The unique difficulty of #cgo pkg-config is that the linker flags are recorded when the package is compiled but (obviously) must be used when the package is linked into an executable -- so the flags need to be stored on disk somewhere. As it happens cgo already writes out a _cgo_flags file: nothing uses it currently, but this change adds it to the lib$pkg.a file when compiling a package, reads it out when linking (and passes a version of the .a file with _cgo_flags stripped out of it to the linker). It's all fairly ugly but it works and I can't really think of any way of reducing the essential level of ugliness. Update golang/go#11739. GCC PR 66904.

There are a few runtime changes anyhow, to accomodate other packages that rely on minor modifications to the runtime support. The compiler changes slightly to add a one-bit flag to each type descriptor kind that is stored directly in an interface, which for gccgo is currently only pointer types. Another one-bit flag (gcprog) is reserved because it is used by the gc compiler, but gccgo does not currently use it.
