Rob Pike authored
For historical reasons, the go/doc package does not include the methods within an interface as part of the documented methods for that type. Thus, go doc ast.Node.Pos gives an incorrect and confusing error message: doc: no method Node.Pos in package go/ast This CL does some dirty work to dig down to the methods so interface methods now present their documentation: % go doc ast.node.pos func Pos() token.Pos // position of first character belonging to the node % It must largely sidestep the doc package to do this, which is a shame. Perhaps things will improve there one day. The change does not handle embeddings, and in principle the same approach could be done for struct fields, but that is also not here yet. But this CL fixes the thing that was bugging me. Change-Id: Ic10a91936da96f54ee0b2f4a4fe4a8c9b93a5b4a Reviewed-on: https://go-review.googlesource.com/31852Reviewed-by:

Some original shift opcodes for ppc64x expected an operand to be a mask instead of a shift count, preventing some valid shift counts from being written. This adds new opcodes for shifts where needed, using mnemonics that match the ppc64 asm and allowing the assembler to accept the full set of valid shift counts.

The old code leaves garbages in a temporary directory because it cannot remove the current working directory on windows. The new code changes the directory before calling os.Remove. Furthermore, the old code assumes that ioutil.TempDir (os.TempDir) doesn't return a relative path nor an UNC path. If it isn't the case, the new code calls t.Fatal earlier for preventing ambiguous errors. Finally, the old code reassigns the variable which is used by the defer function. It could cause unexpected results, so avoid that.
