* runtime: Remove now unnecessary pad field from ParFor.ian2015-10-3190-11473/+2100

| | | | | | | | | | | | | | | | runtime/pprof: Assume function with no name is in runtime. GCC PR 65797 causes some of the runtime functions to be compiled with no name in the debug info. This in turn causes the runtime/pprof test to fail as reported in GCC PR 64683. There are no good choices when a function has no name in the debug info, but here we assume that if we see such a function while reading the runtime functions, we assume that it is also a runtime function. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@222200 138bc75d-0d04-0410-961f-82ee72b054a4

* libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.ian2015-01-1573-499/+11308
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@219627 138bc75d-0d04-0410-961f-82ee72b054a4

* compiler, runtime: Use function descriptors.ian2013-06-182-3/+9
| | | | | | | | | | | | | | | | 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
