* compiler: don't export embedded builtins.ian2013-08-232-3/+28
| | | | | | | | | | | | | The panic in test/fixedbugs/bug461.go was caused by the fact that reflect expects unexported fields in a struct to have a valid package path. If a struct field is an embedded built-in type, it is now given the package name of the currently compiling package, so it remains unexported for purposes of reflect. Fixed Issue 25. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@201951 138bc75d-0d04-0410-961f-82ee72b054a4
* compiler: Don't generate value reference in range clause if receiver is a sink.ian2013-08-171-1/+2
| | | | | | | | | The panic in test/fixedbugs/bug454.go was caused by the generation of an unnecessary var reference when writing a range value into a sink. If the receiving variable is a sink, there's no need to dereference a possible NULL pointer. Fixes Issue 24. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@201815 138bc75d-0d04-0410-961f-82ee72b054a4

* compiler, runtime: Use function descriptors.ian2013-06-1811-286/+942
| | | | | | | | | | | | | | | | This changes the representation of a Go value of function type from being a pointer to function code (like a C function pointer) to being a pointer to a struct. The first field of the struct points to the function code. The remaining fields, if any, are the addresses of variables referenced in enclosing functions. For each call to a function, the address of the function descriptor is passed as the last argument. This lets us avoid generating trampolines, and removes the use of writable/executable sections of the heap. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@200181 138bc75d-0d04-0410-961f-82ee72b054a4
