cmd/vet's printf checker currently uses a hardcoded map of function names to expected positions of format strings. We can be a bit more precise than this by looking up the signature of the function, which helps when libraries implement functions like Errorf or Logf with extra arguments like log levels or error codes. Specifically, the format string param is assumed to be the last string parameter of the called function. Fixes #12294.

Also rewrite bexport.go to use nodeSeqIterate. The new setNodeSeq is a transitional generic function to set either a NodeList or a slice to either a NodeList or a slice. This should permit us to flip fields from *NodeList to []*Node, or Nodes, without changing other code. Passes toolstash -cmp.

The ssa compiler uses the duffcopy and duffzero functions, which rely on the MOVUPS instructions. However, this doesn't work on Plan 9, since floating point operations are not allowed in the note handler. This change disables the use of duffcopy and duffzero on Plan 9 in the ssa compiler.

I tried to write a program to convert *NodeList to Node, but ran into too many problem cases. I'm backing off and trying a more iterative approach using interfaces. This CL adds an interface for iteration over either a *NodeList or a Nodes. I changed typechecklist to use it, to show how it works. After NodeList is eliminated, we can change the typechecklist parameter type to Nodes. Passes toolstash -cmp.

The ODOTPTRs introduced in CL #19814 don't have field names, just offsets. The fieldtrack experiment crashes when examining them. Instead, just ignore them. We'll never track these fields anyway. It would be nice to have the runtime type struct build in the compiler (like we do sudog, for example) so we could use its fieldnames. Doesn't seem worth it just for this CL.

The new Minalign field sets the minimum alignment for all symbols. This is required for the upcoming s390x port which requires symbols be 2-byte aligned for efficient relative addressing. All preexisting architectures have Minalign set to 1 which means that this commit should have no effect. I tested values of 2, 4 and 8 on linux amd64 and the tests appear to pass. Increasing Minalign to 16 appears to break the runtime. I think this is due to assumptions made about the layout of module data. toolstash -cmp on linux amd64 shows no changes due to this commit.

Over the years as more bugs were discovered with the bzip2 library, new Tests were appended the unit tests and the tests became gnarly. Clean up the tests to be more consistent with modern Go style in addition to coalescing common tests into a general version that iterates over a list of input/output pairs. This has the advantage that the input, output, and test code are all in the same area, rather than being sprawled around the test file. There is no loss of test coverage.
