      gc: optimize interface ==, != · f91cc3bd
      Russ Cox authored 
      If the values being compared have different concrete types,
then they're clearly unequal without needing to invoke the
actual interface compare routine.  This speeds tests for
specific values, like if err == io.EOF, by about 3x.

benchmark                  old ns/op    new ns/op    delta
BenchmarkIfaceCmp100             843          287  -65.95%
BenchmarkIfaceCmpNil100          184          182   -1.09%

Fixes #2591.

      gc: fix order of evaluation · ee9bfb02
      Russ Cox authored 
      Pulling function calls out to happen before the
expression being evaluated was causing illegal
reorderings even without inlining; with inlining
it got worse.  This CL adds a separate ordering pass
to move things with a fixed order out of expressions
and into the statement sequence, where they will
not be reordered by walk.

Replaces lvd's CL 5534079.

Fixes #2740.

      gc: implement == on structs and arrays · 196b6630
      Russ Cox authored 
      To allow these types as map keys, we must fill in
equal and hash functions in their algorithm tables.
Structs or arrays that are "just memory", like [2]int,
can and do continue to use the AMEM algorithm.
Structs or arrays that contain special values like
strings or interface values use generated functions
for both equal and hash.

The runtime helper func runtime.equal(t, x, y) bool handles
the general equality case for x == y and calls out to
the equal implementation in the algorithm table.

For short values (<= 4 struct fields or array elements),
the sequence of elementwise comparisons is inlined
instead of calling runtime.equal.

      runtime: prep for type-specific algorithms · b9ccd077
      Russ Cox authored 
      Equality on structs will require arbitrary code for type equality,
so change algorithm in type data from uint8 to table pointer.
In the process, trim top-level map structure from
104/80 bytes (64-bit/32-bit) to 24/12.

Equality on structs will require being able to call code generated
by the Go compiler, and C code has no way to access Go return
values, so change the hash and equal algorithm functions to take
a pointer to a result instead of returning the result.

      gc: clean up printing. · 50110c9f
      Luuk van Dijk authored 
      Got rid of all the magic mystery globals. Now
for %N, %T, and %S, the flags +,- and # set a sticky
debug, sym and export mode, only visible in the new fmt.c.
Default is error mode. Handle h and l flags consistently with
the least side effects, so we can now change
things without worrying about unrelated things
breaking.

fixes #2361

      gc: tweak and enable escape analysis · db5f9da4
      Russ Cox authored 
      -s now means *disable* escape analysis.

Fix escape leaks for struct/slice/map literals.
Add ... tracking.
Rewrite new(T) and slice literal into stack allocation when safe.

Add annotations to reflect.
Reflect is too chummy with the compiler,
so changes like these affect it more than they should.
