[go-nuts] Re: which pass of SSA will transform a ssa.Value(op=OpPhi) phi operations to a normal(not phi operations)?

The regalloc pass does that. It ensures that all the inputs and the output of a phi are all in the same register (or memory location), so the phi becomes a no-op. The regalloc pass doesn't actually remove the phi, though. Removal is actually in genssa in cmd/compile/internal/gc/ssa.go. Look for

[go-nuts] obtaining the original type from a named alias type with go/types?

I would like to be able to obtain the original type for an alias given a source input. I can see in "go/types" that it's possible to know whether a named type is an alias by `typ.Obj().IsAlias()`, but I cannot see how to obtain the actual original type unless it is an alias for a basic type. Can

[go-nuts] Re: Windows 'Access is denied' for os.Remove after exec.Output()

Here's what I think is really going on: At the end of a process's execution, 2 things happen: - The process's code finishes its execution -- wait returns. - The OS closes the executable file. The second item always "comes after" the first. On Windows the delay might be a few milliseconds,

Oh, thanks. The very reason that I do that is to avoid the following situation: for i in `jot 12`; do echo $i > f; git commit -am "$i"; git tag v0.0.$i; done $ git tag -l v0.0.1 v0.0.10 v0.0.11 v0.0.12 v0.0.2 v0.0.3 v0.0.4 v0.0.5 v0.0.6 v0.0.7 v0.0.8 v0.0.9 If no leading 0s allowed, how do you

[go-nuts] which pass of SSA will transform a ssa.Value(op=OpPhi) phi operations to a normal(not phi operations)?

as we know, SSA has phi function, but the output of go tool compile -S xxx.go which do not contains a phi instruction. so i am trying to find out which SSA pass will transform a phi Op ssa.Value to normal ops? -- You received this message because you are subscribed to the Google Groups

that's an invalid semver, no leading 0s allowed https://semver.org/#spec-item-2 : A normal version number MUST take the form X.Y.Z where X, Y, and Z are non-negative integers, and MUST NOT contain leading zeroes. X is the major version, Y is the minor version, and Z is the patch version. Each
