cmd/internal/ld, runtime: record argument size for cgo_dynimport stdcall syscalls When external linking, we must link to implib provided by mingw, so we must use properly decorated names for stdcalls. Because the feature is only used in the runtime, I've designed a new decoration scheme so that we can use the same decorated name for both 386 and amd64. A stdcall function named FooEx from bar16.dll which takes 3 parameters will be imported like this: //go:cgo_import_dynamic runtime._FooEx FooEx%3 "bar16.dll" Depending on the size of uintptr, the linker will later transform it to _FooEx@12 or _FooEx@24. This is in prepration for the next CL that adds external linking support for windows/386.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
