* libgo: If compiler can split-stack and linker can not, use -fno-split-stack.ian2015-09-151-0/+9
| | | | | | | | | | | | | If the compiler supports split-stack but we are using a gold linker that does not, as happens on PPC with current GCC but old gold, then we need to compile the Go code with -fno-split-stack to avoid a linker error avoid the inability to call from split-stack code to non-split-stack code.

* libgo: test linking split-stack and non-split-stack togetherian2015-09-151-2/+26
| | | | | | | | | | | | PPC has split-stack support in current GCC, but old version of gold will reject attempts to link PPC split-stack and non-split-stack code together. Test for that, and don't compile the C code with -fsplit-stack if it doesn't work.

* libgo: Use stat_atim.go on Solaris 12+ian2015-09-101-0/+6
| | | | | | | | | | | | | | From Rainer Orth. Solaris 12 changes the stat_[amc]tim members of struct stat from timestruc_t to timespec_t for XPG7 compatiblity, thus breaking the libgo build. The following patch checks for this change and uses the common stat_atim.go if appropriate.

* libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.ian2015-01-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* runtime: set library name based on compiler nameian2014-11-141-0/+8
| | | | | | | | | | | | Different compilers may have different release cadences or ABI incompatibilities, so it does not make sense to use the same library name for runtime libraries intended for different compilers. This CL causes a libgo built by llgo to receive the name libgo-llgo. Likewise, libgobegin is named libgobegin-llgo. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@217583 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | This adds the --without-libatomic configure option, which is useful for building libgo with a non-gcc compiler. It disables libgo's dependency on libatomic. This is useful for platforms where it is known that the libatomic runtime functions are not required, or where the compiler automatically provides an implementation of them. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@211065 138bc75d-0d04-0410-961f-82ee72b054a4

* compiler, runtime: Use function descriptors.ian2013-06-181-1/+1
| | | | | | | | | | | | | | | | 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
