Make absolute-zero pure virtual fallbacks local and compute runtime archive
interfaces from normalized objects so ORC definitions match JITLink.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
|
|
Resolve the known weak __cxa_pure_virtual reference through the host ABI
instead of JITLink's unsupported absolute-zero fallback. Share the host's
initialized stack guard and failure handler, and map write to _write.

Parse MinGWCOFF.h before windows.h so IMAGE_* macros do not replace LLVM
COFF enum declarations or their uses in the normalization helper.

Associate symbol-less MinGW unwind sections with their code before graph
construction, including objects loaded from runtime archives. Handle suffixed
unwind sections in personality stubs and SEH table registration.

Route external direct CALL/JMP PCRel32 references through nearby JITLink
stubs so user objects can reach distant Windows CRT functions. Reuse the
personality stub tables and preserve data references.

Process-wide lookup can bind EXTERN functions such as puts to ucrtbase.dll,
whose stdout buffer is separate from the host msvcrt used by OUTPUT, so
redirected output can come out of order.

Each EXTERN symbol must be defined by an INCLUDE_OBJ object file or by
the embedded C library selected with INCLUDE_OBJ "__libc". Objects are
linked natively, loaded by the embedded JIT and passed to lli.

Without -o, cpsc saved test.out on every OS, which Windows cannot run
directly. Use .exe under _WIN32 and keep .out elsewhere; update the
manual and architecture notes accordingly.

Replace snprintf+write(2) with a single fprintf call on the platform's
stderr: the C library's stderr / __stderrp, or __acrt_iob_func(2) on
Windows, which the embedded runner binds to the host shim.

Reject builds without an entry program and duplicate cross-file definitions.
Preserve source order for each unit's own constants and import visible exports.

Move ObjectLinkingLayer creation, COFF flags, and SEH plugin install
into one file-local factory used before LLJIT owns the layer. Drop the
repeated dyn_cast checks from the main flow.
Linux verified: build, normal and large-frame runs, exception cases.
Windows layer/plugin behavior still needs CI verification.

Replace the IR personality forwarding layer with graph-local pointer
jump stubs for the three GNU personality symbols in .xdata.
Linux verified: build, nested THROW, cross-procedure unwind, CATCH
with RETURN, uncaught exception. Windows execution still needs CI
verification; the stub pass passed a local LLVM 23 syntax check only.

Drop the hand-written chkstk assembly and bind the toolchain-provided
___chkstk_ms on MinGW x86-64 instead. Other targets register no probe.
Linux verified: build, normal run, large-frame run, exception cases.
Windows/MinGW execution still needs CI verification.

Module and platform graphs each need their own base for 32-bit
image-relative unwind addresses. A graph-local alias keeps the shared
name from colliding at materialization time.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
|
|
Platform-support graphs carry __lljit.platform_support_instance and
manage their own base; aliasing it there duplicates the symbol at
materialization time and spoils the exit code.

getPersonalityFn on a function without the personality operand reads out
of bounds. The newly created stub hit this in the reroute scan.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
|

LLJIT platform-support graphs define their own __ImageBase; aliasing it
again duplicates the symbol and corrupts materialization. Skip those.

COFF unwind tables use 32-bit image-relative addresses. Alias the
external __ImageBase to the lowest defined block once addresses are
final, and route the personality through a JIT-local stub so both stay
within range of the JIT tables.

The weak ___chkstk_ms reference marked the host import weak on COFF and
segfaulted the compiler itself. Provide a JIT-only probe under a unique
name with the same page-touching behavior instead.

Windows runner failed with missing ___chkstk_ms. Reference it weakly so
platforms without it see null while MinGW exposes its host address.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
|
|
Windows runner failed with PCRel32 out of range to __main because the
host executable sits far from the JIT heap under the small code model.

Windows execution awaits CI verification.

Keep JIT sections contiguous and use RuntimeDyld's image base for SEH
registration. Unregister tables before freeing memory and stop execution
when registration fails.

Build LLD from the installed LLVM version's official source release and
install static archives into the local build prefix. Include the Mach-O
unwind headers, preserve static library checks and document the setup.

Save native executables by default and LLVM IR with -S, using source-adjacent
.out and .ll names. Keep -r independent of output selection and update the
manuals and three-platform nightly smoke checks.
BREAKING CHANGE: plain compilation and -o now save native executables.
Use -S to save textual LLVM IR.

Link LLVM, the Clang driver and LLD statically, and embed native link inputs
so executable generation needs no installed development toolchain.
Keep glibc dynamically linked on Linux.

Size REAL buffers for the full fixed-point double range and bound writes with snprintf. Register MinGW CRT aliases for embedded execution.

Check the selected lli only when PATH mode uses -r. Reject missing,
mismatched or unreadable versions before compiling or writing IR, and
limit version detection to five seconds. Keep unused tools unchecked.

Reject other compiler and LLVM major versions and remove GCC compiler
fallbacks. Adapt string globals, block termination checks and the embedded
target triple to LLVM 23 without changing pseudocode behavior.

Add TRY/CATCH/ENDTRY and anonymous THROW statements. Use LLVM exception
handling and the C++ ABI to propagate exceptions across function calls,
clean up catch state, and handle uncaught exceptions at the program boundary.
Register exception runtime symbols for the statically linked embedded runner.
Verify runtime checks, nested catches, returns, loops, and invalid syntax
with smoke programs; exercise unwinding with MCJIT, lli, and native binaries.
BREAKING CHANGE: Runtime check failures now throw anonymous exceptions and
print only a generic message when uncaught. Native binaries require linking
the C++ runtime.

Add EMBEDDED mode to run generated modules in-process without lli or PATH
lookup. Link LLVM and support archives plus the C++ runtime statically,
while retaining the system C runtime on Linux.

Require PATH or NONE at configure time. Reject -r before writing output
when lli is unavailable or execution is disabled.

- MID/RIGHT/LEFT integer args now coerced at call sites (RIGHT(s, n/2)
no longer emits invalid IR); drop emitLeft's private conversion
- FOR loop direction decided at run time via select on STEP sign;
descending FOR works, STEP evaluated once per iteration
- ArrayHandler: extract emitCheckedIndices/loadElement; index count is
validated before emission, fixing a compiler-crash (vector OOB UB) on
OUTPUT with too many indices
- Error contract: Lexer/Parser/CodeGen track errors; all silent failure
paths now print Error: diagnostics with line numbers; unterminated
char literal no longer truncates the rest of the program; module is
verified with verifyModule; driver exits non-zero on any error
