2020-11-20compiler, libgo: change mangling schemeIan Lance Taylor1-1/+1
Overhaul the mangling scheme to avoid ambiguities if the package path contains a dot. Instead of using dot both to separate components and to mangle characters, use dot only to separate components and use underscore to mangle characters. For golang/go#41862 Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/271726

2015-01-15libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.Ian Lance Taylor1-0/+54
This upgrades all of libgo other than the runtime package to the Go 1.4 release. In Go 1.4 much of the runtime was rewritten into Go. Merging that code will take more time and will not change the API, so I'm putting it off for now. 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. There is another error check in the compiler since I ran across it during testing. gotools/: * Makefile.am (go_cmd_go_files): Sort entries. Add generate.go. * Makefile.in: Rebuild. From-SVN: r219627
