* libgo: Update to October 24 version of master library.ian2013-11-061-7/+12
| | | | git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@204466 138bc75d-0d04-0410-961f-82ee72b054a4
* compiler, runtime: Use function descriptors.ian2013-06-181-4/+4
| | | | | | | | | | | | | | | | 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
