Now only cmd/asm and cmd/compile depend on cmd/internal/obj. Changing the assembler backends no longer requires reinstalling cmd/link or cmd/addr2line. There's also now one canonical definition of the object file format in cmd/internal/objabi/doc.go, with a warning to update all three implementations. objabi is still something of a grab bag of unrelated code (e.g., flag and environment variable handling probably belong in a separate "tool" package), but this is still progress. Fixes #15165. Fixes #20026.

TestMultiReaderFlatten determines the call depth by counting PCs returned by runtime.Callers. With inlining, this is incorrect because a PC can represent multiple calls. Furthermore, runtime.Callers might return an additional "skip" PC, which does not represent a real call. This modifies the test to use CallersFrames to determine the call depth. Now the test passes with -l=4. Change-Id: I284f3b1e0b2d194bd08c230c616914503e5a370d Reviewed-on: https://go-review.googlesource.com/40990 Run-TryBot: David Lazar <lazard@golang.org> Reviewed-by:

This is a more thorough and cleaner fix than doing dead code elimination separately during inlining, escape analysis, and export. Unfortunately, it does add another full walk of the AST. The performance impact is very small, but not non-zero. If a label or goto is present in the dead code, it is not eliminated. This restriction can be removed once label/goto checking occurs much earlier in the compiler. In practice, it probably doesn't matter much.

The compiler handled gcargs and gclocals LSyms unusually. It generated placeholder symbols (makefuncdatasym), filled them in, and then renamed them for content-addressability. This is an important binary size optimization; the same locals information occurs over and over. This CL continues to treat these LSyms unusually, but in a slightly more explicit way, and importantly for concurrent compilation, in a way that does not require concurrent modification of Ctxt.Hash. Instead of creating gcargs and gclocals in the usual way, by creating a types.Sym and then an obj.LSym, we add them directly to obj.FuncInfo, initialize them in obj.InitTextSym, and deduplicate and add them to ctxt.Data at the end. Then the backend's job is simply to fill them in and rename them appropriately.

The Frames API forces the PC slice to escape to the heap because it stores it in the Frames object. However, we'd like to use this API for call stack expansion internally in the runtime in places where it would be very good to avoid heap allocation. This commit makes this possible by pulling the bulk of the Frames implementation into an internal frameExpander API. The key difference between these APIs is that the frameExpander does not hold the PC slice; instead, the caller is responsible for threading the PC slice through the frameExpander API calls. This makes it possible to keep the PC slice on the stack. The Frames API then becomes a thin shim around the frameExpander that keeps the PC slice in the Frames object.

Previously the "ABI hash" for a package (used to determine if a loaded shared library has the ABI expected by its loader) was the hash of the entire __.PKGDEF file.

While debugging a recent regression it was discovered that the assembler for ppc64x was not always generating the correct instruction for DS form loads and stores. When an instruction is DS form then the offset must be a multiple of 4, and if it isn't then bits outside the offset field were being incorrectly set resulting in unexpected and incorrect instructions. This change adds a check to determine when the opcode is DS form and then verifies that the offset is a multiple of 4 before generating the instruction, otherwise logs an error. This also changes a few asm files that were using unaligned offsets for DS form loads and stores. In the runtime package these were instructions intended to cause a crash so using aligned or unaligned offsets doesn't change that behavior.

They do basically the same work. Setuintxx was only used in a single place, so eliminate it in favor of WriteInt. duintxxLSym's alignment rounding was not used in practice; change it into alignment assertion. Passes toolstash-check. No compiler performance changes.
