refactor(ssa): rename namedIntf to originType and simplify interface type handling

- Renamed parameter from `namedIntf` to `originType` for clarity
- Removed redundant nil check since `b.abiType()` can handle both Named and Interface types
- Simplified logic by always passing the origin type directly to `b.abiType()`

 **Important:** The `LLGO_ROOT` environment variable must be set to the repository root when running llgo commands during development.
 
-### Update out.ll files after modifying compiler IR generation
-
-**CRITICAL:** When you modify the compiler's IR generation logic (especially in `ssa/` or `cl/` packages), you MUST update all out.ll test files under the `cl/` directory.
-
-#### Understanding out.ll files
-
-The `out.ll` files under the `cl/` directory are comparison IR files that serve as reference outputs for the test suite:
-- They are generated by `llgen` from the corresponding `in.go` files in the same directory
-- They reflect the current compiler's LLVM IR representation of the Go source code
-- They are used by tests to verify that the compiler generates correct and consistent IR output
-
-#### Required steps after modifying IR generation logic
-
-1. **Reinstall the tools** to apply your compiler changes:
-   ```bash
-   go install -v ./chore/gentests
-   go install -v ./chore/llgen
-   ```
-
-2. **Regenerate out.ll files**:
-   
-   **For batch updates (recommended)** - Use `gentests` to regenerate all test files:
-   ```bash
-   gentests
-   ```
-   This will automatically regenerate all out.ll files in these directories:
-   - `cl/_testlibc`
-   - `cl/_testlibgo`
-   - `cl/_testrt`
-   - `cl/_testgo`
-   - `cl/_testpy`
-   - `cl/_testdata`
-   
-   **For individual test inspection** - Use `llgen` to regenerate specific test directories:
-   ```bash
-   llgen cl/_testgo/interface
-   llgen cl/_testrt/tpmethod
-   ```
-
-3. **Verify the changes** make sense by reviewing the diff in the out.ll files
-
-4. **Commit the updated out.ll files** along with your compiler changes
-
-#### Why this matters
-
-This process ensures that:
-- The test suite reflects the current compiler behavior
-- Changes to IR generation are properly documented and reviewed
-- Future regressions can be detected by comparing against the reference output
-
 ## Code Quality
 
 Before submitting any code updates, you must run the following formatting and validation commands:

 ### Defer
 
-LLGo now supports `defer` within loops, matching Go's semantics of executing defers in LIFO order for every iteration. The usual caveat from Go still applies: be mindful of loop-heavy defer usage because it allocates per iteration.
+LLGo `defer` does not support usage in loops. This is not a bug but a feature, because we think that using `defer` in a loop is a very unrecommended practice.

-# Defer Loop GC Integration
-
-## Background
-
-`defer` chains are stored in a per-thread TLS slot so that unwind paths can locate the active `*runtime.Defer`. With the default allocator (`AllocU`) backed by Boehm GC (bdwgc), those TLS-resident pointers were invisible to the collector. In stress scenarios—e.g. `TestDeferLoopStress` with 1,000,000 defers—the collector reclaimed the defer nodes, leaving dangling pointers and causing crashes inside the deferred closures.
-
-Prior experiments (`test-defer-dont-free` branch) confirmed the crash disappeared when allocations bypassed GC (plain `malloc` without `free`), pointing to a root-registration gap rather than logical corruption.
-
-## Solution Overview
-
-1. **GC-aware TLS slot helper** *(from PR [#1347](https://github.com/goplus/llgo/pull/1347))*
-   - Added `runtime/internal/clite/tls`, which exposes `tls.Alloc` to create per-thread storage that is automatically registered as a Boehm GC root.
-   - `SetThreadDefer` delegates to this helper so every thread reuses the same GC-safe slot without bespoke plumbing.
-   - The package handles TLS key creation, root registration/removal, and invokes an optional destructor when a thread exits.
-
-2. **SSA codegen synchronization**
-   - `ssa/eh.go` now calls `runtime.SetThreadDefer` whenever it updates the TLS pointer (on first allocation and when restoring the previous link during unwind).
-   - Defer argument nodes and the `runtime.Defer` struct itself are allocated with `aggregateAllocU`, ensuring new memory comes from GC-managed heaps, and nodes are released via `runtime.FreeDeferNode`.
-
-3. **Non-GC builds**
-   - The `tls` helper falls back to a malloc-backed TLS slot without GC registration, while `FreeDeferNode` continues to release nodes via `c.Free` when building with `-tags nogc`.
-
-## Testing
-
-Run the stress and regression suites to validate the integration:
-
-```sh
-./llgo.sh test ./test -run TestDeferLoopStress
-./llgo.sh test ./test
-```
-
-The updated `TestDeferLoopStress` now asserts 1,000,000 loop defers execute without failure, catching regressions in GC root tracking.

-# Size Report Options
-
-The `llgo build -size` flag emits a TinyGo-style table showing how much code,
-rodata, data, and BSS each component contributes to the final binary. This
-document captures the parsing strategy and new aggregation controls.
-
-## Parsing Strategy
-
-- We invoke `llvm-readelf --elf-output-style=LLVM --all <binary>` and parse the textual output with an
-  indentation-sensitive state machine (no JSON). Only the `Sections` and
-  `Symbols` blocks are inspected.
-- Section metadata records the index, address, size, name, and segment. Each
-  section is classified into text/rodata/data/bss buckets.
-- Symbols are attached to their containing sections with start addresses. By
-  sorting symbols and walking their ranges, we compute byte spans that can be
-  attributed to packages/modules.
-- Sections with no symbols fall back to `(unknown <section>)`, and gaps become
-  `(padding <section>)` entries so totals still add up.
-
-## Aggregation Levels
-
-`-size:level` controls how symbol names are grouped prior to reporting:
-
-| Level     | Behavior                                                                 |
-|-----------|---------------------------------------------------------------------------|
-| `full`    | Keeps the raw owner from the symbol name (previous behavior).             |
-| `package` | Uses the list of packages built in `build.Do` and groups by `pkg.PkgPath`. |
-| `module`* | Default. Groups by `pkg.Module.Path` (or `pkg.PkgPath` if the module is nil). |
-
-Matching is performed by checking whether the demangled symbol name begins with
-`pkg.PkgPath + "."`. Symbols that do not match any package and contain `llgo` are
-bucketed into `llgo-stubs`; other unmatched entries keep their original owner
-names so we can inspect them later.
-
-Examples:
-
-```sh
-llgo build -size .                     # module-level aggregation (default)
-llgo build -size -size:level=package . # collapse by package ID
-llgo build -size -size:level=full .    # show raw symbol owners
-llgo build -size -size:format=json .   # JSON output (works with all levels)
-```
-
-## Validation
-
-1. Unit tests: `go test ./internal/build -run TestParseReadelfOutput -count=1`.
-2. Real binary test:
-   ```sh
-   cd cl/_testgo/rewrite
-   ../../../llgo.sh build .
-   LLGO_SIZE_REPORT_BIN=$(pwd)/rewrite \
-     go test ./internal/build -run TestParseReadelfRealBinary -count=1
-   ```
-3. Manual smoke test: `../../../llgo.sh build -size -size:level=module .` (or
-   `package`/`full` as desired).
-
-The parser works across Mach-O and ELF targets as long as `llvm-readelf` is in
-`PATH`.

-// Package tinygogc implements a conservative mark-and-sweep garbage collector

-//
-// This implementation is based on TinyGo's GC and is designed for resource-constrained
-// embedded systems. It uses a block-based allocator with conservative pointer scanning.
-//
-// Build tags:
-//   - baremetal: Enables this GC for baremetal targets
-//   - testGC: Enables testing mode with mock implementations
-//
-// Memory Layout:
-// The heap is divided into fixed-size blocks (32 bytes on 64-bit). Metadata is stored
-// at the end of the heap, using 2 bits per block to track state (free/head/tail/mark).
