CL 65071 enabled inlining for local closures with no captures. To determine safety of inlining a call sites, we check whether the variable holding the closure has any assignments after its original definition. Unfortunately, that check did not catch OAS2MAPR and OAS2DOTTYPE, leading to incorrect inlining when a variable holding a closure was subsequently reassigned through a type conversion or a 2-valued map access. There was another more subtle issue wherein reassignment check would always return a false positive for closure calls inside other closures. This was caused by the Name.Curfn field of local variables pointing to the OCLOSURE node instead of the corresponding ODCLFUNC, which resulted in reassigned walking an empty Nbody and thus never seeing any reassignments. This CL fixes these oversights and adds many more tests for closure inlining which ensure not only that inlining triggers but also the correctness of the resulting code.

This adds new rules to recognize consecutive byte loads and stores and lowers them to loads and stores such as lhz, lwz, ld, sth, stw, std. This change only covers the little endian cases on little endian machines, such as is found in encoding/binary UintXX or PutUintXX for little endian. Big endian will be done later. Updates were also made to binary_test.go to allow the benchmark for Uint and PutUint to actually use those functions because the way they were written, those functions were being optimized out. Testcases were also added to cmd/compile/internal/gc/asm_test.go.

This CL adds caching of built package files in $GOCACHE, so that a second build with a particular configuration will be able to reuse the work done in the first build of that configuration, even if the first build was only "go build" and not "go install", or even if there was an intervening "go install" that wiped out the installed copy of the first build.

The README is there to help people who stumble across the directory. The access log is there to help us evaluate potential algorithms for managing and pruning cache directories. For now the management is manual: users have to run "go clean -cache" if they want the cache to get smaller. As a low-resolution version of the access log, we also update the mtime on each cache file as they are used by the go command. A simple refinement of go clean -cache would be to delete (perhaps automatically) cache files that have not been used in more than one day, or some suitable time period.

The current code can potentially return a smaller processor count on a linux kernel when its cpumask_size (controlled by both kernel config and boot parameter) is not a multiple of the pointer size, because r/sys.PtrSize will be rounded down. Since sched_getaffinity returns the size in bytes, we can just allocate the buf as a byte array to avoid the extra calculation with the pointer size and roundups.

Usage of atomic.Value has a subtle requirement that the value be of the same concrete type. In prior usage, the intention was to consistently store a value of the error type. Since error is an interface, the underlying concrete can differ. Fix this by creating a type-safe abstraction over atomic.Value that wraps errors in a struct{error} type to ensure consistent types.

The only file that really changed is x/net/idna (upstream 8253218a). See CL 73730: avoid memory leak in validation codes The rest is just a small change in the generation line at the top.

Handle make(map[any]any) and make(map[any]any, hint) where hint <= BUCKETSIZE special to allow for faster map initialization and to improve binary size by using runtime calls with fewer arguments. Given hint is smaller or equal to BUCKETSIZE in which case overLoadFactor(hint, 0) is false and no buckets would be allocated by makemap: * If hmap needs to be allocated on the stack then only hmap's hash0 field needs to be initialized and no call to makemap is needed. * If hmap needs to be allocated on the heap then a new special makehmap function will allocate hmap and intialize hmap's hash0 field. Reduces size of the godoc by ~36kb.

Current AllowedOpCodes is 1024, which is not enough for modern x86. Changed limit to 2048 (though AVX512 will exceed this). Additional Z-cases and ytab tables are added to make it possible to handle missing AVX1 and AVX2 instructions. This CL is required by x86avxgen to work properly: https://go-review.googlesource.com/c/arch/+/66972 Change-Id: I290214bbda554d2cba53349f50dcd34014fe4cee Reviewed-on: https://go-review.googlesource.com/70650 Run-TryBot: Iskander Sharipov <iskander.sharipov@intel.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

Add support for ADX cpuid bit detection and all instructions, implied by that bit (ADOX/ADCX). They are useful for rsa and math/big in general.
