This work-around is not needed anymore now that method signatures are type-checked separately from their receiver base types: no artificial cycles are introduced anymore and so there is no need to artificially cut them.

Remove assumption that methods associated to concrete (non-interface) types have a fully set up signature. Such methods are found through LookupFieldOrMethod or lookupMethod, or indexed method access from a Named type. Make sure that the method's signature is type-checked before use in those cases. (MethodSets also hold methods but the type checker is not using them but for internal verification. API clients will be using it after all methods have been type-checked.) Some functions such as MissingMethod may now have to type-check a method and for that they need a *Checker. Add helper functions as necessary to provide the additional (receiver) parameter but permit it to be nil if the respective functions are invoked through the API (at which point we know that all methods have a proper signature and thus we don't need the delayed type-check). Since all package-level objects eventually are type-checked through the top-level loop in Checker.packageObjects we are guaranteed that all methods will be type-checked as well. Updates #23203. Updates #26854. Change-Id: I6e48f0016cefd498aa70b776e84a48215a9042c5 Reviewed-on: https://go-review.googlesource.com/c/139425Reviewed-by:

The prior CL prepared go/types for the situation where methods might not have a type-checked signature when being looked up. The respective adjustments to recvPtr were not correct (but because so far method signatures are type-checked in time, the bug didn't manifest itself). Updates #23203. Updates #26854.

The alloc_m documentation refers to concepts that don't exist (and maybe never did?). alloc_m is also not the API entry point to span allocation. Hence, rewrite the documentation for alloc and alloc_m. While we're here, document why alloc_m must run on the system stack and replace alloc_m's hand-implemented system stack check with a go:systemstack annotation.

.rel symbol type is sym.SELFROSECT, and that makes .rel written into .rdata section. But .rel stores code - jump table used for external C functions. So we have to mark whole .rdata section as executable (IMAGE_SCN_MEM_EXECUTE), because of .rel presence in it. Move .rel into .text section, and make .rdata section non executable. I also had to move code that adjusted the size of .rel symbol before calling textaddress, otherwise textaddress would not calculate size of .text section correctly.

Currently "ADD $0x123456, Rs, Rd" will load pre-stored 0x123456 from the constant pool and use it for the addition. Total 12 bytes are cost. And so does SUB. This CL breaks it to "ADD 0x123000, Rs, Rd" + "ADD 0x000456, Rd, Rd". Both "0x123000" and "0x000456" can be directly encoded into the instruction binary code. So 4 bytes are saved. 1. The total size of pkg/android_arm64 decreases about 0.3KB. 2.

Currently the table of arena sizes mixes the number of entries in the L1 with the size of the L2. While the size of the L2 is important, this makes it hard to see what's actually going on because there's an implicit factor of sys.PtrSize. This changes the L2 column to say both the number of entries and the size that results in. This should hopefully make the relations between the columns of the table clearer, since they can now be plugged directly into the given formula.

LookupFieldOrMethod needs to know if a method receiver is a pointer type. Until now this was computed from the the method signature's receiver, which required the method signature to be type-checked. Furthermore, it required the receiver to be set before the method signature was fully type-checked in some cases (see issue #6638). This CL remembers this property during object resolution, when we know it from the source. With this CL, method signatures don't need to be type-checked before they can be looked up; this is a first step towards separating type checking of types and type-checking of associated methods.

In preparation for followup CL merging TPTR32 and TPTR64, move TPTR32 from the small-types fast path to the generic 64-bit fallback code so that it's in the same case clause as TPTR64. This should be safe, but theoretically it could change semantics because TPTR32 used to always be assumed to be "small", whereas now it will only be considered small for values less than 1<<31. This change is done in a separate CL so that it's more easily identified by git bisection in case it does introduce regressions.

When an invalid UTF-8 byte sequence is decoded in a range loop over a string a utf8.RuneError rune is returned. This is not distinguishable from decoding the valid '\uFFFD' sequence representing utf8.RuneError from a string without further checks within the range loop. The previous Map code did not do any extra checks and would thereby not map invalid UTF-8 byte sequences correctly when those were mapping to utf8.RuneError. Fix this by adding the extra checks necessary to distinguish the decoding of invalid utf8 byte sequences from decoding the sequence for utf8.RuneError when the mapping of a rune is utf8.RuneError. This fix does not result in a measureable performance regression: name old time/op new time/op delta ByteByteMap 1.05µs ± 3% 1.03µs ± 3% ~ (p=0.118 n=10+10) Map/identity/ASCII 169ns ± 2% 170ns ± 1% ~ (p=0.501 n=9+10) Map/identity/Greek 298ns ± 1% 303ns ± 4% ~ (p=0.338 n=10+10) Map/change/ASCII 323ns ± 3% 325ns ± 4% ~ (p=0.679 n=8+10) Map/change/Greek 628ns ± 5% 635ns ± 1% ~ (p=0.460 n=10+9) MapNoChanges 120ns ± 4% 119ns ± 1% ~ (p=0.496 n=10+9) Fixes #26305 Change-Id: I70e99fa244983c5040756fa4549ac1e8cb6022c3 Reviewed-on: https://go-review.googlesource.com/c/131495Reviewed-by:

Currently, the Windows profile loop isn't robust against racing with unminit. For example, T1 is running profileloop1, T2 is another thread T1: thread := atomic.Loaduintptr(&T2.thread) T2: calls unminit, which does CloseHandle(T2.thread) T1: attempts to suspends T2 In this case the SuspendThread will fail, but currently we ignore this failure and forge ahead, which will cause further failures and probably bad profile data. Handle this race by defending against SuspendThread failing. If SuspendThread succeeds, then we know the thread is no longer going anywhere.

The debug call injection tests will freeze when run under a debugger because they depend on catching SIGTRAP, which is usually swallowed by a debugger.

And start using it elsewhere in the standard library, removing the copies in the process. While at it, rewrite the io.WriteString godoc to be more clear, since it can now make reference to the defined interface. Fixes #27946.
