Xgo v1.2.0

This release upgrades xgo from v1.1.14 to v1.2.0

Major feature:

• Support Go 1.25
• New DSL Patching Syntax That Is More AI Friendly

To install xgo v1.2.0:

# upgrade xgo
go install github.com/xhd2015/xgo/cmd/xgo@v1.2.0

# update runtime
go get github.com/xhd2015/xgo/runtime@v1.2.0

Additional Notes

CLI Update:

• --use-file-patches — force file-based patches
• --patch-goroot-in-place — skip GOROOT copy (used by xgo setup)

Patch DSL:
Declarative, AST-aware patch language (instrument/patch/apply_engine.go) for
.xgo.patch files. Commands: goto, match, find_for_replace,
insert_before, insert_after, insert_after_line, replace,
replace_directive, copy_func, newline. Patches are idempotent: named
blocks clear previous edits before re-applying.

Other Improvements

• Per-version CI workflows (go1.17–go1.25)
• script/go-patch-diff, script/run-github-workflow-via-act utility scripts
• Extensible test scanning with go-max version constraint
• New func_names test suite for overlay stub naming across file counts
• Development docs for overlay restriction, compiler debugging, patch checklists

Known Side Effects

• Closure numbering in func_names shifts on Go 1.25 due to additional
  compiler-autogen stubs from because go1.25 forbids overlay in GOCACHE

Issues Resolved

1. Runtime self-require: needLocalRuntime injected self-require when CI
   tests xgo/runtime itself. Fixed by skipping self-require when main module IS
   the runtime.

2. Windows: stale .exe shadows new compiler: After GOROOT rebuild,
   compile.exe (old) shadowed compile (new) due to Windows PATHEXT priority.
   Fixed by adding .exe suffix to -o outputs on Windows.

3. Windows: raw string position bug: \r bytes in raw string literals (from
   git core.autocrlf) caused ast.BasicLit.End() to return incorrect positions.
   Fixed by normalizing \r\n → \n at file load.

4. Windows: git core.autocrlf injects \r: Documented root cause and
   reproduction.

5. go/scanner inconsistency (upstream): scanRawString() strips \r from
   value but not file position. xgo's \r\n normalization is the workaround.

6. SelectorExpr panic: ParseReceiverType panicked on *otherpkg.Type
   receivers. Fixed by unwrapping *ast.SelectorExpr.

7. LC_UUID on macOS 26+: Go <1.23 binaries lack LC_UUID, rejected by dyld.
   Fixed with -linkmode=external for darwin/arm64 hosts on Go <1.23.
