In typecheckclosure, a xfunc node will be put to xtop. But that node can be shared between multiple closures, like in a const declaration group: const ( x = unsafe.Sizeof(func() {}) y ) It makes a xfunc node appears multiple times in xtop, causing duplicate initLSym run. To fix this issue, we only do typecheck for xfunc one time, and setup closure node earlier in typecheckclosure process.

When we construct the build list by loading packages (e.g., in "go build", "go list", or "go test"), we may load additional modules not mentioned in the original build list. If we encounter an error loading one of these modules, mvs.BuildList currently returns a BuildListError with a chain of requirments. Unfortunately, this is not helpful, since the graph is structured such that these missing modules are direct requirements of the main module. With this change, loader.load keeps track of the package that caused each "missing" module to be added. If an error occurs in a missing module, the chain of package imports is printed instead of the module requirements.

mvs.BuildList reports errors with a chain of modules to make it clear why the module where the error occurred was part of the build. This is a little confusing with "go get -u" since there are edges in the module graph for requirements and for updates. With this change, we now print "requires" or "updates to" between each module version in the chain.

RELNOTE=yes The new escape analysis pass is more precise, which for most Go code should be an improvement. However, it may also break code that happened to work before (e.g., code that violated the unsafe.Pointer safety rules). The old escape analysis pass can be re-enabled with "go build -gcflags=all=-newescape=false". N.B., it's NOT recommended to mix the old and new escape analysis passes such as by omitting "all=". While the old and new escape analysis passes use similar and mostly compatible metadata, there are cases (e.g., closure handling) where they semantically differ and could lead to memory corruption errors in compiled programs. Fixes #23109.

The existing implementation has poor performance for inserting large number of keys because it chooses to append the new key to the sorted keys array and then sort the new array again (time complexity is O(nlogn)). The improvement tries to utilize the sorted keys array by searching the index and doing an insertion if any (time complexity is O(logn)).

The new escape analysis implementation tries to emit debugging diagnostics that are compatible with the existing implementation, but there's a handful of cases that are easier to handle by updating the test expectations instead. For regress tests that need updating, the original file is copied to oldescapeXXX.go.go with -newescape=false added to the //errorcheck line, while the file is updated in place with -newescape=true and new test requirements. Notable test changes: 1) escape_because.go looks for a lot of detailed internal debugging messages that are fairly particular to how esc.go works and that I haven't attempted to port over to escape.go yet. 2) There are a lot of "leaking param: x to result ~r1 level=-1" messages for code like func(p *int) *T { return &T{p} } that were simply wrong. Here &T must be heap allocated unconditionally (because it's being returned); and since p is stored into it, p escapes unconditionally too. esc.go incorrectly reports that p escapes conditionally only if the returned pointer escaped. 3) esc.go used to print each "leaking param" analysis result as it discovered them, which could lead to redundant messages (e.g., that a param leaks at level=0 and level=1). escape.go instead prints everything at the end, once it knows the shortest path to each sink. 4) esc.go didn't precisely model direct-interface types, resulting in some values unnecessarily escaping to the heap when stored into non-escaping interface values. 5) For functions written in assembly, esc.go only printed "does not escape" messages, whereas escape.go prints "does not escape" or "leaking param" as appropriate, consistent with the behavior for functions written in Go. 6) 12 tests included "BAD" annotations identifying cases where esc.go was unnecessarily heap allocating something. These are all fixed by escape.go. Updates #23109.

A handful of packages were reimplementing IsExported, so use token.IsExported instead. This caused the deps test to fail for net/rpc. However, net/rpc deals with Go types, and go/token is light and fairly low-level in terms of Go tooling packages, so that's okay. While at it, replace all uses of ast.IsExported with token.IsExported. This is more consistent, and also means that the import graphs are leaner. A couple of files no longer need to import go/ast, for example. We can't get rid of cmd/compile/internal/types.IsExported, as the compiler can only depend on go/token as of Go 1.4. However, gc used different implementations in a couple of places, so consolidate the use of types.IsExported there. Finally, we can't get rid of the copied IsExported implementation in encoding/gob, as go/token depends on it as part of a test. That test can't be an external test either, so there's no easy way to break the import cycle. Overall, this removes about forty lines of unnecessary code.

This CL adds the following instructions, useful for shifting/rotating and masking operations: * RNSBG - rotate then and selected bits * ROSBG - rotate then or selected bits * RXSBG - rotate then exclusive or selected bits * RISBG - rotate then insert selected bits It also adds the 'T' (test), 'Z' (zero), 'H' (high), 'L' (low) and 'N' (no test) variants of these instructions as appropriate. Operands are ordered as: I₃, I₄, I₅, R₂, R₁. Key: I₃=start, I₄=end, I₅=amount, R₂=source, R₁=destination Change-Id: I200d12287e1df7447f37f4919da5e9a93d27c792 Reviewed-on: https://go-review.googlesource.com/c/go/+/159357 Run-TryBot: Michael Munday <mike.munday@ibm.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

Allow up to 3 RestArgs arguments to be specified. This is needed to for us to add the 'rotate and ... bits' instructions, which require 5 arguments, cleanly.

The existing pclntab construction took care to re-use strings: filenames and fully qualified function names. It did not try to deduplicate pctab information, perhaps because the author assumed that there wouldn't be much duplication. This change introduces that deduplication. The cache gets a 33% hit rate during make.bash. This doesn't require any changes to the file format, and shrinks binaries by about 1%.
