Code Review
This pull request introduces several significant enhancements. A comprehensive test suite for gogen is added to validate llgo's compatibility. The build system is improved with a new -x flag to print commands and a more flexible build.sh script. A major part of this PR is the implementation of defer and panic support for baremetal targets using setjmp/longjmp. Additionally, interface assertion logic is made more robust to handle methods that might be stripped by dead code elimination. The changes are well-structured and include relevant tests. My review found one area for improvement in a shell script to reduce code duplication.

_demo/embed/targetsbuild/build.sh (101-178)
The ignore_list definitions for empty and defer share a large number of common targets. To improve maintainability and reduce duplication, you could define a common list of ignored targets and then append test-specific ones.
# Define common ignore list
common_ignore_list=(
"atmega1280"
"atmega2560"
"atmega328p"
"atmega32u4"

Code Review SummaryThis PR adds a comprehensive gogen package test suite demonstrating llgo's compatibility with gogen's code generation APIs. The changes include:
Critical Issue FoundCompilation Error: The Areas Reviewed
The baremetal defer support and interface method lookup changes are well-designed. The new jump buffer sizes for ARM, AVR, Cortex-M, RISC-V, and Xtensa architectures include proper source references to picolibc/newlib. See inline comments for specific issues. |

Critical: Compilation Error
This calls testTypeSwitch2() which is commented out (lines 858-885). This will cause a compilation error:
undefined: testTypeSwitch2
Since the test is marked as IGNORED due to a known bug (issue #1604), this call should be removed:
| testTypeSwitch2() | |
| // testTypeSwitch2() - IGNORED: see https://github.com/goplus/llgo/issues/1604 |

Outdated

Minor: Batch comment incomplete
The header says "Batch 1: tests 1-5, Batch 2: tests 6-15" but the file contains tests up to 29 (with test 29 ignored). Consider updating:
| // Converted from package_test.go for llgo testing | |
| // Batch 1: tests 1-5, Batch 2: tests 6-15 | |
| // Converted from package_test.go for llgo testing | |
| // Tests 1-28 active, Test 29 (testTypeSwitch2) ignored due to issue #1604 |

@xgopilot move to _demo/gogen/package, with this sturcture the test_demo.sh will correct process this test! and rename to package.go！

Completed: File moved and renamed ✅
- Created directory
_demo/gogen/package/ - Moved and renamed file to
_demo/gogen/package/package.go - Fixed compilation error (commented out call to
testTypeSwitch2()) - Committed and pushed changes
Changes pushed: Created PR #192 in your fork to merge the changes to this PR branch.
The test file is now at _demo/gogen/package/package.go which will be correctly processed by test_demo.sh.
