* | | cmd/cc, cmd/ld, runtime: disallow conservative data/bss objectsRuss Cox2014-09-241-1/+3

In the linker, attach the Go type to an already-read C declaration during dedup. This gives us Go types for C globals for free as long as the cmd/dist-generated Go code contains the declaration. (Most runtime C declarations have a corresponding Go declaration. Both are bss declarations and so the linker dedups them.) In cmd/dist, add a few more C files to the auto-Go-declaration list in order to get Go type information for the C declarations into the linker. In C compiler, mark all non-pointer-containing global declarations and all string data as NOPTR. This allows them to exist in C files without any corresponding Go declaration. Count C function pointers as "non-pointer-containing", since we have no heap-allocated C functions. In runtime, add NOPTR to the remaining pointer-containing declarations, none of which refer to Go heap objects. In runtime, also move os.Args and syscall.envs data into runtime-owned variables. Otherwise, in programs that do not import os or syscall, the runtime variables named os.Args and syscall.envs will be missing type information. I believe that this CL eliminates the final source of conservative GC scanning in non-SWIG Go programs, and therefore... Fixes issue 909.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there is a leading ?, assume there is a Go prototype and attach the Go prototype information to the function. If the function is not called from Go and does not need a Go prototype, it can be made file-local instead (using name<>(SB)). This fixes the current BSD build failures, by giving functions like sync/atomic.StoreUint32 argument stack map information. Fixes issue 8753.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary because syscall.Syscall blocks, and the garbage collector needs to be able to scan that frame while it is blocked, and C frames have no garbage collection information.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, Syscall and friends were having their arguments treated conservatively. Now they will use the Go prototype, which will mean the arguments are not considered pointers at all. This is safe because of CL 139360044. The fact that all these non-Solaris systems were using conservative scanning of the Syscall arguments is why the failure that prompted CL 139360044 was only observed on Solaris, which does something completely different. If we'd done this earlier, we'd have seen the Solaris failure in more places. LGTM=khr R=khr CC=golang-codereviews https://codereview.appspot.com/144730043

* | | syscall: keep allocated C string live across call to SyscallRuss Cox2014-09-0829-23/+607
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given: p := alloc() fn_taking_ptr(p) p is NOT recorded as live at the call to fn_taking_ptr: it's not needed by the code following the call. p was passed to fn_taking_ptr, and fn_taking_ptr must keep it alive as long as it needs it. In practice, fn_taking_ptr will keep its own arguments live for as long as the function is executing. But if instead you have: p := alloc() i := uintptr(unsafe.Pointer(p)) fn_taking_int(i) p is STILL NOT recorded as live at the call to fn_taking_int: it's not needed by the code following the call. fn_taking_int is responsible for keeping its own arguments live, but fn_taking_int is written to take an integer, so even though fn_taking_int does keep its argument live, that argument does not keep the allocated memory live, because the garbage collector does not dereference integers. The shorter form: p := alloc() fn_taking_int(uintptr(unsafe.Pointer(p))) and the even shorter form: fn_taking_int(uintptr(unsafe.Pointer(alloc()))) are both the same as the 3-line form above. syscall.Syscall is like fn_taking_int: it is written to take a list of integers, and yet those integers are sometimes pointers. If there is no other copy of those pointers being kept live, the memory they point at may be garbage collected during the call to syscall.Syscall. This is happening on Solaris: for whatever reason, the timing is such that the garbage collector manages to free the string argument to the open(2) system call before the system call has been invoked. Change the system call wrappers to insert explicit references that will keep the allocations alive in the original frame (and therefore preserve the memory) until after syscall.Syscall has returned. Should fix Solaris flakiness. This is not a problem for cgo, because cgo wrappers have correctly typed arguments.
