2017-09-12cmd/compile: improve single blank variable handling in walkrangeMartin Möhrmann
Refactor walkrange to treat "for _ = range a" as "for range a". This avoids generating some later discarded nodes in the compiler. Passes toolstash -cmp.

2016-10-28cmd/compile: move stringtoslicebytetmp to the backendMartin Möhrmann
- removes the runtime function stringtoslicebytetmp - removes the generation of calls to stringtoslicebytetmp from the frontend - adds handling of OSTRARRAYBYTETMP in the backend This reduces binary sizes and avoids function call overhead.

2013-02-11test: a number of fixes.Alan Donovan
Details: - reorder.go: delete p8. (Once expectation is changed per b/4627 it is identical to p1.) - switch.go: added some more (degenerate) switches. - range.go: improved error messages in a few cases. - method.go: added tests of calls to promoted methods.

2012-05-24cmd/gc: fix parallel assignment in rangeRuss Cox
for expr1, expr2 = range slice was assigning to expr1 and expr2 in sequence instead of in parallel. Now it assigns in parallel, as it should. This matters for things like for i, x[i] = range slice. Fixes #3464. R=ken2 CC=golang-dev https://golang.org/cl/6252048
