The FP load/store on arm64 have register indexed forms. And this CL implements this optimization. 1. The total size of pkg/android_arm64 (excluding cmd/compile) decreases about 400 bytes. 2.

In the compiler frontend, walkinrange indiscriminately calls Int64() on const CTINT nodes, even though Int64's return value is undefined for anything over 2⁶³ (in practise, it'll return a negative number). This causes the introduction of bad constants during rewrites of unsigned expressions, which make the compiler reject valid Go programs. This change introduces a preliminary check that Int64() is safe to call on the consts on hand. If it isn't, walkinrange exits without doing any rewrite.

Given the following types: type S2 struct{ Field string } type S struct{ *S2 } Marshalling a value of type T1 should result in "{}", as there's no way to access any value of T2.Field. This is how Go 1.10 and earlier versions behave. However, in the recent refactor golang.org/cl/125417 I broke this logic. When the encoder found an anonymous struct pointer field that was nil, it no longer skipped the embedded fields underneath it. This can be seen in the added test: --- FAIL: TestAnonymousFields/EmbeddedFieldBehindNilPointer (0.00s) encode_test.go:430: Marshal() = "{\"Field\":\"\\u003c*json.S2 Value\\u003e\"}", want "{}" The human error was a misplaced label, meaning we weren't actually skipping the right loop iteration. Fix that.

TestRawMessage now passes without the need for the RawMessage field to be a pointer. The TODO dates all the way back to 2010, so I presume the issue has since been fixed. TestNullRawMessage tested the decoding of a JSON null into a *RawMessage. The existing behavior was correct, but for the sake of completeness a non-pointer RawMessage field has been added too. The non-pointer field behaves differently, as one can read in the docs: To unmarshal JSON into a value implementing the Unmarshaler interface, Unmarshal calls that value's UnmarshalJSON method, including when the input is a JSON null.

Encoders like map and array can use the much cheaper "i > 0" check to see if we're not writing the first element. However, since struct fields support omitempty, we need to keep track of that separately. This is much more expensive - after calling the field encoder itself, and retrieving the field via reflection, this branch was the third most expensive piece of this field loop. Instead, hoist the branch logic outside of the loop. The code doesn't get much more complex, since we just delay the writing of each byte until the next iteration. Yet the performance improvement is noticeable, even when the struct types in CodeEncoder only have 2 and 7 fields, respectively. name old time/op new time/op delta CodeEncoder-4 5.39ms ± 0% 5.31ms ± 0% -1.37% (p=0.010 n=4+6) name old speed new speed delta CodeEncoder-4 360MB/s ± 0% 365MB/s ± 0% +1.39% (p=0.010 n=4+6) Updates #5683.

A few encoder struct types, such as map and slice, only encapsulate other prepared encoder funcs. Using pointer receivers has no advantage, and makes calling these methods slightly more expensive. Not a huge performance win, but certainly an easy one.

FLDPI pushes the constant pi to 387's register stack, which is more efficient than MOVSSconst/MOVSDconst. 1. This optimization reduces 0.3KB of the total size of pkg/linux_386 (exlcuding cmd/compile). 2.

Before this CL we would build&run each test file individually. Building the test takes most of the time, a significant fraction of a second. Running the tests are really fast. After this CL, we build all the tests at once, then run each individually. We only have to run the compiler&linker once (or twice, for softfloat architectures) instead of once per test. While we're here, organize these tests to fit a bit more into the standard testing framework. This is just the organizational CL that changes the testing framework and migrates 2 tests. Future tests will follow.
