Remove all uses of Node.Val outside of the gc package. A subsequent, automated commit in the Go 1.6 cycle will unexport Node.Val. No functional changes. Passes toolstash -cmp. Change-Id: Ia92ae6a7766c83ab3e45c69edab24a9581c824f9 Reviewed-on: https://go-review.googlesource.com/9267Reviewed-by:

Preallocating them in reflect means that (1) if you say _ = PtrTo(ArrayOf(1000000000, reflect.TypeOf(byte(0)))), you just allocated 1GB of data (2) if you say it again, that's *another* GB of data. The only use of t.zero in the runtime is for map elements. Delay the allocation until the creation of a map with that element type, and share the zeros. The one downside of the shared zero is that it's not garbage collected, but it's also never written, so the OS should be able to handle it fairly efficiently.

According to MSDN RegQueryValueEx page: If the data has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, the string may not have been stored with the proper terminating null characters. Therefore, even if the function returns ERROR_SUCCESS, the application should ensure that the string is properly terminated before using it; otherwise, it may overwrite a buffer. (Note that REG_MULTI_SZ strings should have two terminating null characters.)

It's dumb to clear them in initSpan, set them in heapBitsSetType, clear them in heapBitsSweepSpan, set them again in heapBitsSetType, clear them again in heapBitsSweepSpan, and so on. Set them in initSpan and be done with it (until the span is reused for objects of a different size). This avoids an atomic operation in a common case (one-word allocation).

This reduces the depth of the inlining at a particular call site. The inliner introduces many temporary variables, and the compiler can do a better job with fewer. Being verbose in the bodies of these helper functions seems like a reasonable tradeoff: the uses are still just as readable, and they run faster in some important cases.

The Transport's writer to the remote server is wrapped in a bufio.Writer to suppress many small writes while writing headers and trailers. However, when writing the request body, the buffering may get in the way if the request body is arriving slowly. Because the io.Copy from the Request.Body to the writer is already buffered, the outer bufio.Writer is unnecessary and prevents small Request.Body.Reads from going to the server right away. (and the io.Reader contract does say to return when you've got something, instead of blocking waiting for more). After the body is finished, the Transport's bufio.Writer is still used for any trailers following. A previous attempted fix for this made the chunk writer always flush if the underlying type was a bufio.Writer, but that is not quite correct. This CL instead makes it opt-in by using a private sentinel type (wrapping a *bufio.Writer) to the chunk writer that requests Flushes after each chunk body (the chunk header & chunk body are still buffered together into one write).

The code generated for a slice x[i:j] or x[i:j:k] computes the entire new slice (base, len, cap) and then uses it as the evaluation of the slice expression. If the slice is part of an update x = x[i:j] or x = x[i:j:k], there are opportunities to avoid computing some of these fields. For x = x[0:i], we know that only the len is changing; base can be ignored completely, and cap can be left unmodified. For x = x[0:i:j], we know that only len and cap are changing; base can be ignored completely. For x = x[i:i], we know that the resulting cap is zero, and we don't adjust the base during a slice producing a zero-cap result, so again base can be ignored completely. No write to base, no write barrier. The old slice code was trying to work at a Go syntax level, mainly because that was how you wrote code just once instead of once per architecture. Now the compiler is factored a bit better and we can implement slice during code generation but still have one copy of the code. So the new code is working at that lower level. (It must, to update only parts of the result.)

The spec explains later in the "Operator precedence" section that * has a higher precedence than +, but the current production rule requires that "1 + 2 * 3" be parsed as "(1 + 2) * 3", instead of the intended "1 + (2 * 3)". The new production rule better matches cmd/internal/gc/go.y's grammar: expr: uexpr | expr LOROR expr | expr LANDAND expr | ... Fixes #10151.
