This is a framework for docs on the subject more than it is actual docs. The section header in go/doc.go just says "C", not "C/C++," because otherwise godoc doesn't recognize the line as a section header. Fixes #5473. R=golang-dev, r CC=golang-dev https://golang.org/cl/13280050

This eliminates ~75% of the nil checks being emitted, on all architectures. We can do better, but we need a bit more general support from the compiler, and I don't want to do that so close to Go 1.2. What's here is simple but effective and safe. A few small code generation cleanups were required to make the analysis consistent on all systems about which nil checks are omitted, at least in the test. Fixes #6019.

47ec7a68b1a2 added support for ECDSA ciphersuites but didn't alter the cipher suite selection to take that into account. Thus Go servers could try and select an ECDSA cipher suite while only having an RSA certificate, leading to connection failures. R=golang-dev, rsc CC=golang-dev https://golang.org/cl/13239053

The root cause of the panic reported in https://code.google.com/p/go/issues/detail?id=5980 is that parse's Tree.Text wasn't being copied during the clone. Fix this by adding and using a Copy method for parse.Tree. Fixes #5980. R=golang-dev, r CC=golang-dev https://golang.org/cl/12420044

This interface is required to use the PCDATA interface implemented in Go 1.2. While initially entirely private, the FUNCDATA side of the interface has been made public. This change completes the FUNCDATA/PCDATA interface. R=golang-dev, rsc CC=golang-dev https://golang.org/cl/13735043

Hide container symbols like text and etext so that the individual pieces inside are shown instead. For example, if text and main.init have the same address, it was a toss-up which name was printed. R=golang-dev, iant CC=golang-dev https://golang.org/cl/13722046

The code for call site-specific pointer bitmaps was not ready in time, but the zeroing required without it is too expensive to use by default. We will have to wait for precise collection of stack frames until Go 1.3. The precise collection can be re-enabled by GOEXPERIMENT=precisestack ./all.bash but that will not be the default for a Go 1.2 build. Fixes #6087.

The uint64 divide function calls _mul64x32 to do a 64x32-bit multiply and then compares the result against the 64-bit numerator. If the result is bigger than the numerator, must use the slow path. Unfortunately, the 64x32 produces a 96-bit product, and only the low 64 bits were being used in the comparison. Return all 96 bits, the bottom 64 via the original uint64* pointer, and the top 32 as the function's return value. Fixes 386 build (broken by ARM division tests).

This CL is required for all.bat to work out of the box on my Windows 8 laptop. These tests either require the firewall to be turned off or require the user to be in the Administrators group. I don't know which. Alex may follow up with a refinement of the test to allow them to run if the user is in the Administrators group. Fixes #6392.

The kernel implementation of the fast system call path, the one invoked by the SYSCALL instruction, is broken for restarting system calls. A C program demonstrating this is below. Change the system calls to use INT $0x80 instead, because that (perhaps slightly slower) system call path actually works. I filed http://www.freebsd.org/cgi/query-pr.cgi?pr=182161. The C program demonstrating that it is FreeBSD's fault is below. It reports the same "Bad address" failures from wait. #include <sys/time.h> #include <sys/signal.h> #include <pthread.h> #include <unistd.h> #include <stdlib.h> #include <stdio.h> #include <string.h> static void handler(int); static void* looper(void*); int main(void) { int i; struct sigaction sa; pthread_cond_t cond; pthread_mutex_t mu; memset(&sa, 0, sizeof sa); sa.sa_handler = handler; sa.sa_flags = SA_RESTART; memset(&sa.sa_mask, 0xff, sizeof sa.sa_mask); sigaction(SIGCHLD, &sa, 0); for(i=0; i<2; i++) pthread_create(0, 0, looper, 0); pthread_mutex_init(&mu, 0); pthread_mutex_lock(&mu); pthread_cond_init(&cond, 0); for(;;) pthread_cond_wait(&cond, &mu); return 0; } static void handler(int sig) { } int mywait4(int pid, int *stat, int options, struct rusage *rusage) { int result; asm("movq %%rcx, %%r10; syscall" : "=a" (result) : "a" (7), "D" (pid), "S" (stat), "d" (options), "c" (rusage)); } static void* looper(void *v) { int pid, stat, out; struct rusage rusage; for(;;) { if((pid = fork()) == 0) _exit(0); out = mywait4(pid, &stat, 0, &rusage); if(out != pid) { printf("wait4 returned %d\n", out); } } } Fixes #6372.
