Add extensive test coverage, demo program, and CI integration for
//export with different names feature:
Unit Tests (cl/builtin_test.go):
- TestHandleExportDiffName: core functionality with 4 scenarios
* Different names with enableExportRename
* Same names with enableExportRename
* Different names with spaces in export directive
* Matching names without enableExportRename
- TestInitLinknameByDocExportDiffNames: flag behavior verification
* Export with different names when enabled
* Export with same name when enabled
* Normal linkname directives
- TestInitLinkExportDiffNames: edge case handling
* Symbol not found in decl packages (silent handling)
Demo (_demo/embed/export/):
- Example program demonstrating various export patterns
- Verification script testing both embedded and non-embedded targets
- Documents expected behavior and error cases
CI Integration (.github/workflows/llgo.yml):
- Add export demo to embedded target tests
- Ensure feature works correctly across platforms
- Catch regressions in future changes
The tests verify:
✓ Different names work with -target flag
✓ Same names work in all cases
✓ Different names fail without -target flag
✓ Proper error messages for invalid exports
✓ Silent handling for decl packages
