Project Progress and Learning / Re: How far are we? Lets take...

Last post by Stan Duraham - Yesterday at 09:36:38 PM

To be honest, the few PowerBASIC users who remain are perfectly happy with the old 32‑bit compiler, and they will continue using it indefinitely.

There is no real demand for a new compiler, because the existing one already does everything they need — and most of them are not interested in switching tools or workflows at this point.

That's also why community feedback is so limited: the user base is small, aging, and largely static. They are not looking for innovation; they are looking for stability.

... and there can't be any new users.

For me, PowerBASIC is somewhat like PDS 7.1 a product from a previous generation that may eventually fade away as its user base continues to shrink.

That could explain why Jürgen didn't receive much feedback. Nowadays there are several good alternatives, including FreeBASIC, PureBasic, or simply plain C for developers who are familiar with the underlying Win32 API

Deepseek is the cheapest KI, yet even  "V4 Flash" can do any coding task and is 1/10 th of the price from the big prooviders.
In my tests it even beats Minimax M3 and is much cheaper.

In short: Deepseek is not the best but especially "V4 Flash" API is so cheap that this alone can put pressure on all other providers.

Imagine you have 2 Taxi's - one very compfortable and you pay $100 and a competition one with a hard seat and you pay $5.

The point is:
BOTH bring you from A to B. Which will most people take?

Built a dynamic long long array that grows and shrinks as needed. Supports quick sort and binary search, insert and delete. To/From file.

All from one script.
The hardest part; it built a complete test application.

Then had it convert that file to all; integer, unsigned inter and floating-point type arrays. Along with test apps.

Then had it build a dynamic string array from one script, along with complete test app. Still need to add split and join, and to/from text file.

All sort and binary search operations can use a custom or default callback.

This is just with the free online version, do have to open an account. Did have to feed a few errors back in, particularly on the floats. Ony takes a few seconds. Took a long time to build the scripts.

Goal, make C more BASIC like. String manipulation is going to be tough.

Last post by Theo Gottwald - June 05, 2026, 10:41:24 PM

The whole compiler ist just some steps forward from the one i posted here with sourcedode some time ago.

There is also CX32 - a Powerbasic compiler in Powerbasic.
But progress is slower due to Ki has problems with Powerbasic- not with C.
Also the compilation speed of this c version is much faster.

Intentionally i did not favor any of these but just let the AI continue work on these.
The surprising result is that this compiler made fastest progress.

If you like to test it send me a message, you can be the second to get it.

Test it. Then you can tell me how it feels. Does it give the PB-Feeling?
Thats what counts.

The reason i did that was not mainly for the public.
Thats a bit diffrent from Jürgen.

He told me that he was a bit dissapointed in the few interst in his project
and other then me - HE REALLY used a lot of heartblood for his compiler.
So he told me that he will do some private things first and pick it up in direction october.

So for me it was that feeling to have the option to add ANY Command or anything that i have in mind to this new compiler, without asking anybody and explaining anybody why, or what.

Others may use it too. So if you want to try it drop me a msg.
In a few day i hope to put it online on the web-site anyway.

The current version still does not pass all tests.

Its still the case that every day someone finds something that needs to be done first ...

Test 021 (`DO_WHILE_loop`) — **6.43× slower** than PBWin:
```asm
lea eax, [ebp-8]       ; &i
mov eax, [eax]         ; load i from stack
mov [ebp-16], eax      ; spill to another stack slot
mov edx, [ebp-16]      ; reload
cmp edx, 100000
```
PBWin keeps `i` in `ECX` or `EDX`. PBXA32 does a 5-instruction stack dance per increment.

**Fix target:** `src/codegen/codegen_ra_linear_scan.inc` — promote high-use `alloca` values (especially loop induction variables) to physical registers.

### 2. Missing `SDIV` Strength Reduction
The optimizer rewrites `MUL` → `SHL` and `UDIV` → `LSHR`, but **has no rewrite for signed division**. Test 072 (`shift_right__divide`) still emits full `CDQ`+`IDIV` for `i \ 2`.

**Fix target:** `src/optimizer/pipeline_strength.inc`

### 3. Array Access Through Runtime Helpers
Even fixed-size local arrays call `__pbxa32_lnarr_get` / `__pbxa32_lnarr_set` instead of inline `base + (index * size)` addressing.

**Fix target:** `src/ir/lowering_expr_main.inc`, `src/ir/lowering_stmt_assign.inc`

### 4. String/Math Builtins as Runtime Calls
`LEFT$`, `CHR$`, `ASC`, `ATN`, `CHOOSE` — all call into `pbxa32rt.o` every iteration. `CHOOSE` is lowered to nested `IIF` runtime calls instead of a jump table.

**Fix target:** `src/codegen/codegen_intrinsics_main.inc`, `src/ir/lowering_builtins_string_core.inc`

## What This Means for W2–W5

The analyzer's findings **validate the worker assignments** and add precision:

- **W3 (Loop Optimizer)** — The #1 and #4 defects confirm that register-promoting loop counters is the highest-impact fix. The ASM shows exactly where to intervene.
- **W2 (Array Codegen)** — Confirmed: arrays go through `__pbxa32_lnarr_get/set`. The fix is to bypass these for fixed local arrays.
- **W5 (Intrinsic Inliner)** — Confirmed: `CHR$`, `ASC`, `LEFT$`, `ATN`, `CHOOSE` are all runtime calls. The inline paths are well-defined.
- **W4 (Opt Pass Enabler)** — The missing `SDIV`→`SAR` strength reduction is a perfect target for the optimizer pipeline. Also, enabling `sparse-dce` would remove the redundant stack spills shown in the ASM.

**W2–W5 are still running.** I'll report again as each completes. The first to finish will likely be W5 (intrinsics — self-contained changes) or W2 (arrays — focused scope).

## Swarm State — Active Progress Update

All **4 coder workers (W2–W5)** are actively editing source files. Here's the live diff from their worktrees:

| Worker | Files Modified | Key Changes |
|--------|---------------|-------------|
| **W2 — Arrays** | 5 files | `lowering_builtins_array.inc` +129B, `codegen.c` +522B, `codegen_emit_ir_ops.inc` −1,019B |
| **W3 — Loops** | 4 files | `codegen_ra_linear_scan.inc` −2,397B (**major RA refactor**), `codegen.c` +522B, `codegen_emit_ir_ops.inc` −1,019B |
| **W4 — Opt Pass** | 6 files | `analysis.c` −2,482B (**alias analysis added**), `pipeline.c` +725B, `pipeline_opt_passes.inc` −599B |
| **W5 — Intrinsics** | 3 files | `codegen_intrinsics_helpers.inc` −1,789B (**inlined helpers**), `codegen_intrinsics_main.inc` −161B |

### Notable Observations

1. **W3 cut `codegen_ra_linear_scan.inc` by 2,397 bytes** — This is a significant reduction, likely removing redundant spill code or consolidating the register allocator. This directly addresses the #1 defect from W1's report (stack-only locals).

2. **W4 cut `analysis.c` by 2,482 bytes** — Likely replaced placeholder/stub code with actual alias analysis. This enables `sparse-dce`.

3. **W2, W3, and W4 all touched the same 3 files** (`lowering_control_loops.inc`, `codegen.c`, `codegen_emit_ir_ops.inc`) with **identical byte deltas**. This suggests they may have made the same or compatible changes — good for clean merging.

4. **W5 built `PBXA32.exe`** and generated test BAS files (`_test__061.bas` through `_test__079.bas`) — actively validating the inline intrinsic changes.

### W1 Status
✅ **COMPLETE** — DEFECT_REPORT.md delivered. The 10-test analysis identified 4 root cause clusters with specific file targets. All 4 coder workers are now addressing these exact defects.

### Next Milestones
- W5 appears closest to completion (built + testing)
- W3's RA refactor is the highest-impact change
- W4's alias analysis unlocks the disabled optimizer passes
- W2's array bypass is the most complex (touches semantic + lowering + codegen)

**All workers are still running.** I'll merge and verify as each commits.

# PBXA32 Project Analysis — Where We Are

## Executive Summary

**PBXA32** is a full-stack compiler for **PowerBASIC syntax** written in **ISO C11**, targeting **32-bit x86 PE-COFF executables** on Windows. It is a from-scratch implementation of a commercial-grade BASIC compiler with its own lexer, parser, semantic analyzer, SSA-like IR, optimizer pipeline, x86 native code generator, COFF assembler, and PE32 linker.

**Current version**: 0.2.0 (A15 integration) 
**Codebase**: ~100+ C source files + `.inc` fragments, well over 100,000 lines of C 
**Build host**: MinGW-w64 GCC 15.2+ on Windows

---

## Compiler Architecture (Front-to-Back)

| Stage | Status | Key Files |
|-------|--------|-----------|
| **Lexer** | ✅ Complete | `src/lexer/lexer.c`, `token.c` — case-insensitive keywords, typed identifiers, literals, compound assignments |
| **Preprocessor** | ✅ Complete | `src/preprocessor/preprocessor.c` — multi-pass `#INCLUDE`, directives, macros |
| **Parser** | ✅ Complete | `src/parser/parser.c` + 20+ `.inc` fragments — recursive-descent AST, namespaces, classes, interfaces, full statement set |
| **Semantic Analyzer** | ✅ Complete | `src/semantic/analyzer.c`, `typesys.c`, `symbols.c` — type system, symbol tables, builtin registration |
| **IR (Lowering)** | ✅ Active | `src/ir/lowering.c` + 30+ `.inc` fragments — AST → SSA-like IR with value IDs, basic blocks, intrinsics |
| **Optimizer** | ⚠️ Shallow | `src/optimizer/pipeline.c`, `analysis.c` — mem2reg, copyprop/CSE, instcombine, strength reduction; **sparse-dce disabled at O2**, **licm-lite disabled at O3** |
| **x86 Codegen** | ✅ Complete | `src/codegen/codegen.c` + 15+ `.inc` fragments — EBP-framed locals, stack allocation, vreg allocator, inline asm support |
| **Assembler** | ✅ Complete | `src/assembler/object_writer.c` — COFF object writer with `.text/.rdata/.data/.bss`, MODRM/SIB encoding, debug info |
| **Linker** | ✅ Complete | `src/linker/linker.c` — PE32 linker with import thunks, exports, startup thunk, BSS handling |
| **Runtime** | ✅ Complete | `src/runtime/pbxa32rt.c` + containers + math — freestanding 32-bit runtime, no CRT dependency |

---

## Current Verification State

### Benchmarks (100-test suite vs PBCC / PBWin / SB)
- **Compile-time**: PBXA32 wins on **all 93** compiled tests — ~2.4× faster than PBCC, ~2.4× faster than PBWin
- **Runtime**: PBXA32 wins only **4/83** vs PBWin — PBWin is ~1.2× faster overall, SB ~0.6×
- **Correctness**: **93/100** tests compile, run, and produce matching exit codes
- **7 tests** fail to compile (mostly directives: `ENUM`, `TYPE`, `MACRO`, `JOIN`, `SPLIT` in some configs, `ON_ERROR_GOTO`, `HEX/OCT/BIN`)

### Stage Tests (Internal)
- **Smoke tests**: 15/15 PASS
- **E2E tests**: 47/47 PASS 
- **Stage tests**: 79/92 PASS (13 pre-existing failures, not regressions)

### Known Pre-Existing Failures
1. **`#DIM ALL` + `FOR EACH`** — parser/analyzer gap with implicit declarations
2. **`ON ERROR GOTO`** — codegen pending
3. **`CCODE` / `CVARGET` / `DECLARE`** — C interop edge cases
4. **File I/O stages** (`stage_ap_fileio2`, `stage_ay2_xprint`) — pre-existing runtime issues
5. **Optimizer golden IR mismatch** — expected, pipeline is evolving
6. **`TIME$` / `DATE$` `LEN()`** — string pointer tracking bug
7. **`MACRO` runtime crash** — preprocessor expansion edge case

---

## Recent Work (Last Session — A15 Integration)

The most recent commit (`a124dee`) integrated A15 with:
- 100% assembler coverage + 8-bit full pipeline
- Fixed `BITSET`/`BITRESET` lowering via new intrinsic path
- Fixed `INCR`/`DECR` with 2-argument step values
- Fixed `SPLIT` array statement (parser + lowering + analyzer)
- Fixed `REPEAT$` crash (0xC0000005) — parameter order corrected in runtime
- Fixed `ENUM` member linker error (symbol table lookup)
- Fixed `#DIM ALL` rejecting new builtins

---

## Where the Leverage Is (Open Work)

### 1. **Runtime Performance** (Biggest Gap)
PBXA32 compiles faster but runs slower than PBWin. The README explicitly states:
> *"Array codegen and loop-heavy control flow are still the largest runtime hot spots."*

This is where an x86/optimization expert would focus:
- Array access lowering generates suboptimal addressing modes
- Loop control flow (FOR/WHILE/DO) has overhead from the EBP-frame style
- The optimizer pipeline is "shallow" — mem2reg and instcombine run, but LICM and aggressive DCE are disabled because the codegen can't yet handle the IR shapes they produce

### 2. **Optimizer Pipeline Depth**
Two passes are explicitly disabled:
- `sparse-dce` at O2 — *"memory deps not traced"*
- `licm-lite` at O3 — *"codegen forward-reference issue"*

Unlocking these would likely close the runtime gap with PBWin.

### 3. **Long-Tail Language Features**
- Deep COM support
- `ON ERROR GOTO` (control-flow exception model)
- `MACRO` preprocessor expansion stability
- `JOIN` / `SPLIT` full array runtime
- `HEX$` / `OCT$` / `BIN$` string formatting

---

## Build & Development Workflow

```powershell
# Full compiler build
.\build_compiler.ps1

# Run full test lane
powershell -File test_lane\run_all.ps1

# 100-test benchmark vs PBCC/PBWin
powershell -File test_lane\run_bench_100.ps1
```

The compiler is built as a **64-bit host executable** (`PBXA32.exe`) that cross-compiles to **32-bit x86 PE** targets. The target runtime is compiled separately with `-m32 -ffreestanding -nostdlib` and linked into user programs.

---

## Bottom Line

**You have a functionally complete, correctness-verified PowerBASIC compiler that successfully compiles and runs ~93% of a 100-test benchmark suite against the commercial reference compilers (PBCC, PBWin).**

The compiler is **solid on correctness** and **wins on compile-time speed**. The remaining work is **runtime performance optimization** (array codegen, loop lowering, enabling the disabled optimizer passes) and **long-tail feature completion** (COM, error handling, a few string builtins).

This is no longer a "can we build a compiler?" project. It is a **"can we make it faster than the incumbent?"** project. The architecture is sound; the IR and optimizer are the next leverage points.

Meta Forum / IONOS - what do we do?

Last post by Theo Gottwald - June 05, 2026, 08:30:12 PM

I have today talked with the Provider support on the phone.

The result is simple: I pay this provider since 25 years.
Since ~1 Year we have lots of trouble with WEB-Hosting.

If we have more dropouts of this forum FROM TODAY,
the switch to a new provider will happen.

So anybody reading here can also see if that works or still doesn't work.
Its not that i will accept LESS DROPOUTs.

We get zero dropouts or we leave IONOS. After 25 Years.

🚨 IONOS Webhosting: Eine Chronik wiederkehrender Probleme

📋 Zusammenfassung

IONOS (ehemals 1&1) ist Deutschlands größter Hosting-Anbieter mit Sitz in Montabaur und Rechenzentren in Karlsruhe und Frankfurt. Doch hinter der Fassade eines "zuverlässigen" Anbieters verbirgt sich eine alarmierende Historie wiederkehrender Ausfälle, Storage-Problemen und struktureller Infrastruktur-Mängel.

⚠️ Auch unser Forum ist betroffen!

Dieses Forum wird auf IONOS gehostet — und leidet unter denselben ständigen Störungen. 😤

Trotz Unlimited-Tarif und aller angebotenen Performance-Optionen (erhöhte PHP-Limits, SSD-Speicher, volle Datenbank-Ressourcen) erleben wir:
• Regelmäßige HTTP 500-Fehler und komplette Erreichbarkeits-Ausfälle
• DNS-Probleme und willkürliche Redirects
• Langsame Ladezeiten trotz aller verfügbaren Optimierungen
• Fehlende Cache-Dateien nach Server-Updates, die nicht automatisch neu generiert werden
• Datenbank-Verbindungsabbrüche ohne Vorwarnung

Wir zahlen für "Unlimited" und bekommen "Unbegrenzte Probleme". 💸➡️🗑�

🔥 Aktueller Vorfall: Heute — Kompletter Ausfall des Forums

05. Juni 2026: Unser Forum ist komplett offline. Jede einzelne PHP-Seite liefert HTTP 500:

• `forum.it-berater.org/` → 500
• `index.php?topic=...` → 500
• `cron.php` → 500
• `?action=keepalive` → 500

Sogar die SMF-System-Cronjobs schlagen fehl. Das ist kein kleines Problem — das ist ein Totalausfall aller PHP-Funktionalität. 🔥

🔧 Die IONOS-Migration: Ein Albtraum

Als wir vor Kurzem ein Forum-Update samt Migration durchführen mussten, offenbarten sich weitere systemische Mängel der IONOS-Infrastruktur:

• PHP-Cross-Directory-Sperren: PHP-Skripte können nicht über Verzeichnisse hinweg auf Dateien zugreifen — "Read-only file system" / "No such file". Ein einfaches Kopieren von Dateien zwischen `/forum/` und `/newforum/` ist über PHP unmöglich. 🤦
• Minified-Cache-Desaster: SMF erzeugt CSS/JS-Cache-Dateien mit Hash-basierten Namen (`minified_<hash>.css`). Nach Server-Updates oder Migrationen werden diese nicht automatisch neu generiert. Ergebnis: kaputtes Layout, fehlende Styles, unbedienbare Buttons. Man muss die Dateien manuell vom alten zum neuen Verzeichnis kopieren — was wegen Punkt 1 nur per SFTP geht. 😤
• Webspace-Explorer-Timeouts: Der IONOS-Webspace-Explorer bricht beim Kopieren größerer Dateimengen mit HTTP 504 ab. Dateioperationen müssen stundenlang in kleinen Häppchen durchgeführt werden. ⏳
• Datenbank-Migration mit verbundenen Augen: Kein direkter Datenbank-Zugriff, keine Import/Export-Tools — nur das langsame Durchschleusen über PHP.

Diese Probleme existieren nicht bei anderen Hostern. Das ist reine IONOS-Infrastruktur-Schikane.

📞 Der IONOS-Support: Ein Trauerspiel

Wir haben mindestens 5 Mal beim IONOS-Support angerufen. Das Ergebnis war jedes Mal erschreckend gleich:

• Falsche Diagnosen: Statt das reale Problem zu analysieren, wurden wir mit vorgeschobenen Erklärungen abgespeist — "Liegt an Ihrer Software", "Ihr Traffic ist zu hoch", "Sie müssen Ihre Datenbank optimieren".
• Upsell-Druck statt Lösungen: Jeder Anruf endete mit dem Verkaufsargument, wir müssten zusätzliche Produkte kaufen — mehr Speicher, höhere PHP-Limits, Premium-Datenbank, CDN, whatever. Wir haben sie gekauft. Es hat nichts genützt. 💰🚫
• Keine Eskalation möglich: Techniker, die das Problem nicht verstehen, verweigern die Weiterleitung an höhere Ebenen.
• Widersprüchliche Aussagen: Jeder Mitarbeiter erzählt etwas anderes.

Fazit: Der IONOS-Support ist kein Support — es ist ein Vertriebskanal mit Warteschleife. 📞💸

🔴 Aktuelle & Jüngste Ausfälle (2025–2026)

🏗� Wiederkehrende Infrastruktur-Probleme

1. Storage/NFS-Ausfälle in Karlsruhe (das große Muster) 🎯

EGroupware, ein auf IONOS-Hosting betriebener Dienst, dokumentierte seit 2022 über ein Dutzend Storage-bedingte Totalausfälle:

• 26.01.2026 — "Problem on the storage system at IONOS"
• 09.01.2024 — "Problem on the NFS server (Storage from IONOS)"
• 04.10.2023 — "EGroupware cluster hangs due to an issue with the NFS server"
• 26.03.2025 — Wiederholte Verbindungsabbrüche zwischen PHP-Pods und NFS-Speicher — IONOS konnte keine Lösung finden
• 19.08.2023 — Storage-System-Ausfall in Frankfurt, Tunnel-Zusammenbruch Karlsruhe↔Frankfurt, Mail-Ausfall über Stunden

2. Stromausfälle & Power-Probleme ⚡

Im November 2023 berichtete DataCenter-Insider über einen schwerwiegenden Vorfall:

"Ein komplexer, verteilter Rechner- und Speicherverbund mag es gar nicht, wenn zweimal innerhalb kurzer Zeit der Strom weg ist."

Betroffen waren:
• 8 virtuelle Datacenter bei IONOS (4× Frankfurt, 4× Karlsruhe)
• 26 Server exklusive Loadbalancer
• Ceph-Storage-Cluster mit Ausfall mehrerer Knoten
• Red Hat OpenShift Compute-Cluster

Das Rechenzentrum wird von Equinix betrieben, das 99,9999% Verfügbarkeit wirbt — was 31,56 Sekunden Ausfall pro Jahr entspricht. Die Realität sah anders aus.

📉 Fazit & Call-to-Action

IONOS mag Deutschlands größter Hosting-Anbieter sein — doch die dokumentierte Historie zeigt ein erschreckendes Muster:

🔴 Wiederkehrende Storage-Ausfälle im Karlsruher Rechenzentrum
🔴 Stromausfälle trotz redundanter Infrastruktur
🔴 Netzwerk-Probleme zwischen den beiden deutschen Standorten
🔴 Langsame Support-Reaktionszeiten und ungelöste Tickets
🔴 Mehrere Tage dauernde Totalausfälle
🔴 Absurde Support-Erfahrungen mit Upsell-Druck statt Lösungen

Und das Schlimmste: Auch mit dem teuersten Unlimited-Tarif und allen Performance-Extras bleibt der Service unzuverlässig. Wir zahlen Premium und bekommen Premium-Probleme. 🏚�

📊 Umfrage: Soll das Forum zu einem anderen Hoster umziehen?

• ✅ Ja, sofort — IONOS ist untragbar
• ⚠️ Ja, aber erst wenn das Forum wieder läuft
• ❌ Nein, die Probleme sind akzeptabel
• 🤷 Ich habe keine Meinung dazu

Diskutiert mit! 💬
