When the func value is needed (e.g. with\nValue.Interface), it is lazily converted to the func Value\nrepresentation. The lazy conversion has a bad escape behavior: it\nflows the Value to the a heap-allocated methodValue structure,\nwhich causes the Value to escape. This in turn causes operations\nlike Value.Interface or Value.Convert escape its receiver to heap,\nas they have a code path to handle the lazy conversion of method\nValue, even if this code path is not taken.\n\nTo avoid the unnecessary escape, this CL changes the method Value\nrepresentation to eagerly creating the func Value. This eliminates\nthe code path with bad escape behavior in operations like\nValue.Interface.\n\nThe lazy representation does have an advantage: Call on the method\nValue is simple, as the method\u0027s code expects the receiver as the\nfirst parameter, instead of a closure with the receiver pre-bound.\nKeeping the receiver and the method index in the Value allows Call\nto find the code pointer and pass the receiver directly. With the\nfunc Value representation, Call has to unmarshal and re-marshal\nthe arguments in order to shift them by one. To avoid this problem,\nwe save the receiver and the method index in the closure structure\n(i.e. methodValue structure), and set a special flag, so Call on\nsuch a Value can still take the fast path, instead of going\nthrough the closure. Benchmark result shows that Call on such a\nValue is as fast as before, but creating the method Value is\nslower as it involes an allocation. Creating a method Value and\nthen doing operations like Interface/Convert/Set is mostly\nunchanged, as it just moves a lazy operation earlier.\n\nChange-Id: I70beab0b816c8b0587a1b414e804ec3061c39e43\nReviewed-on: https://go-review.googlesource.com/c/go/+/799760\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: David Chase \u003cdrchase@google.com\u003e\n" }, { "commit": "fb60d8cdb2fd2d21008e24ade1ade2caeae86ab5", "tree": "d72a1ed801b68448fdd087ff533716a031ac3b45", "parents": [ "1c3a1bac8b14c866d70b330e0229e5555670f577" ], "author": { "name": "Filippo Valsorda", "email": "filippo@golang.org", "time": "Wed Jul 15 10:36:24 2026 +0200" }, "committer": { "name": "Gopher Robot", "email": "gobot@golang.org", "time": "Tue Jul 21 04:24:11 2026 -0700" }, "message": "crypto/mldsa: handle some uninitialized and nil values more gracefully\n\nFixes #79959\nFixes #80339\nFixes #80344\n\nChange-Id: Id1b7d1a726e138b9b3f4df91c00259586a6a6964\nReviewed-on: https://go-review.googlesource.com/c/go/+/800860\nReviewed-by: Daniel McCarney \u003cdaniel@binaryparadox.net\u003e\nReviewed-by: Roland Shoemaker \u003croland@golang.org\u003e\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nAuto-Submit: Filippo Valsorda \u003cfilippo@golang.org\u003e\nReviewed-by: Dmitri Shuralyov \u003cdmitshur@google.com\u003e\n" }, { "commit": "1c3a1bac8b14c866d70b330e0229e5555670f577", "tree": "618d4805e2b049e3715d873c43bce637bb50f168", "parents": [ "0c0dacdf0b84a675b51b9ddfe61d9e331356fe8b" ], "author": { "name": "Nicholas S.

But the analysis doesn\u0027t\nhandle the case where a use of the address is itself just a copy or\npointer arithmetic, and the result of that use is then subsequently\nused outside the lifetime we currently compute.\n\nMaybe we could track down uses of uses, etc. But we do the safer thing\nhere which is just to consider only uses that we know aren\u0027t propagating\nthe address anywhere. Any other uses are considered bad and abort\nmerging for the affected local. This is conservative but easy to reason\nabout. In practice, these address copies don\u0027t come up all that often,\nas they are usually folded into load/store ops. The only typical use\nof an explicit address is initial zeroing (which this CL handles).\n\nFixes #80127\n\nChange-Id: Ia722a8314c1ace1b883ecedec1a3e06a2957a6b6\nReviewed-on: https://go-review.googlesource.com/c/go/+/796001\nReviewed-by: Junyang Shao \u003cshaojunyang@google.com\u003e\nReviewed-by: Keith Randall \u003ckhr@google.com\u003e\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\n" }, { "commit": "088195b6fbddf2860949c79af530260eb172c268", "tree": "ef66fbe8730aea3671ac09e81154613ad99d6117", "parents": [ "5128514a6bf790e82827f3b3130f6b8abb1285c2" ], "author": { "name": "Michael Matloob", "email": "matloob@golang.org", "time": "Mon Jul 13 18:04:34 2026 -0400" }, "committer": { "name": "Gopher Robot", "email": "gobot@golang.org", "time": "Mon Jul 20 11:09:54 2026 -0700" }, "message": "cmd/compile/internal/ssa: move Register to ssabase package and BlockKind to block subpackage\n\nThis is the first step in a refactoring to break the ssa package into smaller\npackages.

"message": "cmd/compile: add align128 compiler marker for 128-bit struct alignment\n\nAdd an align128 sentinel type to sync/atomic and\ninternal/runtime/atomic, analogous to align64. Embedding `_ align128`\nin a struct causes the compiler to enforce 16-byte alignment on the\ncontaining struct.\n\nThis is required for 128-bit atomic operations (CMPXCHG16B on amd64,\nCASP on arm64), which require a 16-byte-aligned memory operand. A\nstruct containing two uint64 fields has natural alignment of 8 bytes,\nso it may otherwise be placed at a non-16-byte-aligned offset within a\nlarger struct, causing faults or incorrect behavior.\n\nNo test: align128 is unexported in sync/atomic, and testing it in internal\nwould create cyclic dependencies with reflect.\n\nFor #61236.\n\nChange-Id: Iab0502776141aed309457b462f2fdb60ec0d5245\nGitHub-Last-Rev: 8cf379404d04c1fbe2b011975d5932eb9d9225da\nGitHub-Pull-Request: golang/go#79991\nReviewed-on: https://go-review.googlesource.com/c/go/+/790320\nReviewed-by: Robert Griesemer \u003cgri@google.com\u003e\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Keith Randall \u003ckhr@google.com\u003e\nReviewed-by: Dmitri Shuralyov \u003cdmitshur@google.com\u003e\n" }, { "commit": "61b0b6dd8419c44ad8e7575bf72c569715088e35", "tree": "6243146d097ff3fbf304555d95c4b56bc1147d4c", "parents": [ "339fd9cf0a40a336df0ea4839db543a6e26f4c20" ], "author": { "name": "Meng Zhuo", "email": "mengzhuo@iscas.ac.cn", "time": "Thu Jul 02 10:00:30 2026 +0800" }, "committer": { "name": "Meng Zhuo", "email": "mengzhuo@iscas.ac.cn", "time": "Thu Jul 16 02:31:20 2026 -0700" }, "message": "runtime: use sigaction syscalls when cgo is enabled on riscv64\n\nThis ensures that runtime\u0027s signal handlers pass through the TSAN and\nMSAN like arm64/loong64 does.\n\nChange-Id: I3f6ef61a96e5f1f4c5b68eb5703e77b2dba7dbe9\nReviewed-on: https://go-review.googlesource.com/c/go/+/796100\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Russ Cox \u003crsc@golang.org\u003e\nReviewed-by: Cherry Mui \u003ccherryyz@google.com\u003e\n" }, { "commit": "339fd9cf0a40a336df0ea4839db543a6e26f4c20", "tree": "bcfea2a1c02c2fb5b911ea351cd037e86406c725", "parents": [ "d888e9e41969cd4cbd5f1a54234704cc1f8cae0d" ], "author": { "name": "Alex Brainman", "email": "alex.brainman@gmail.com", "time": "Mon Jun 15 15:45:15 2026 +1000" }, "committer": { "name": "Alex Brainman", "email": "alex.brainman@gmail.com", "time": "Wed Jul 15 23:33:52 2026 -0700" }, "message": "cmd/internal/script: correct interrupt process implementation\n\nInterrupt process uses cmd.Process.Signal(os.Interrupt).\nBut that call is not implemented on Windows.\nUse cmd.Process.Kill() instead.\n\nThis CL also adds small test to test the code.\n\nUpdates #77485.\n\nChange-Id: Ie0e2326aa3c4c49a20c71e48caf1409c699c41c2\nReviewed-on: https://go-review.googlesource.com/c/go/+/796480\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Russ Cox \u003crsc@golang.org\u003e\nReviewed-by: Michael Pratt \u003cmpratt@google.com\u003e\nReviewed-by: Quim Muntal \u003cquimmuntal@gmail.com\u003e\n" }, { "commit": "d888e9e41969cd4cbd5f1a54234704cc1f8cae0d", "tree": "d456a0f38c25c05f9d848e7563248250b1edefc5", "parents": [ "831c5835d953e31e14eff4da267422ba15374d14" ], "author": { "name": "Dmitri Shuralyov", "email": "dmitshur@golang.org", "time": "Fri May 08 13:23:22 2026 -0400" }, "committer": { "name": "Gopher Robot", "email": "gobot@golang.org", "time": "Wed Jul 15 20:35:58 2026 -0700" }, "message": "cmd/go/internal/telemetrystats: drop go/platform/target/{goos,goarch}:*\n\nThey provide a subset of the information that the newer port:*-* counter\nprovides, making them generally redundant.
