2015-09-15libgo: If compiler can split-stack and linker can not, use -fno-split-stack.Ian Lance Taylor1-1/+2
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.

2015-09-15libgo: don't provide ustat on arm64 GNU/LinuxIan Lance Taylor1-159/+230
This avoids linker warnings when linking against glibc, as apparently arm64 GNU/Linux does not support the ustat system call. Also update to automake 1.11.6, as that is the new GCC standard. Reviewed-on: https://go-review.googlesource.com/14567 From-SVN: r227777
2015-09-10libgo: Use stat_atim.go on Solaris 12+Ian Lance Taylor1-1/+2
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. Reviewed-on: https://go-review.googlesource.com/14495 From-SVN: r227665
2015-08-03syscall: RawSockaddr fix for ppc64, ppc64leIan Lance Taylor1-0/+5
The struct RawSockaddr contains a field Data which should be uint8 on ppc64 and ppc64le, but is declared as int8 in gccgo. This change adds a two new files which contain the structure declaration for RawSockaddr, one with the correct types for for ppc64 and ppc64le, and the other for non-ppc64 platforms.

Generate the list of the standard GO package names based on what was built into libgo in the libgo Makefile. Change the var name from reqPkgSrc to reqStdPkgSrc to clarify it only affects standard GO packages. Skip the attempted loading of a package only if it is a standard GO package and the flag is set indicating its source is not required to be available. This requires a corresponding change to gotools to build and link in the new file containing the list of standard GO package names that was generated by the libgo Makefile. gotools/: PR go/65462 * Makefile.am (go_cmd_go_files): Add $(libgodir)/zstdpkglist.go. * Makefile.in: Rebuild.

Change from using __go_set_closure to passing the closure value in the static chain field. Uses new backend support for setting the closure chain in a call from C via __builtin_call_with_static_chain. Uses new support in libffi for Go closures. The old architecture specific support for reflect.MakeFunc is removed, replaced by the libffi support.

2015-01-15libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.Ian Lance Taylor1-27/+78
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. From-SVN: r219627

2014-11-14runtime: set library name based on compiler nameIan Lance Taylor1-37/+54
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. From-SVN: r217583

2013-06-18compiler, runtime: Use function descriptors.Ian Lance Taylor1-10/+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. From-SVN: r200181
