The `links` field in `ParsedAsmResultLine` and the `AsmResultLink` type
have been unused since 2019 when clickable address links were replaced
by the labels system. This just removes the dead code.
Closes#8251
Closes#6319Closes#6320
Adds two new opt-in filter checkboxes to the LLVM IR view's **Filters**
dropdown:
### Hide Declarations (off by default)
Filters external function declaration lines (lines starting with
`declare`). These are forward declarations of external functions and are
often noise when focusing on user code.
**Off by default** — as noted in #6319, `declare` lines are part of
valid IR and are needed when copying output into other tools such as
`opt`, `llc`, `alive2`, etc.
### Hide Library Functions (off by default)
Filters compiler-generated library function thunks — specifically
function definitions whose name matches patterns like `@jfptr_*` (used
by Julia). These are boilerplate wrapper functions that aren't useful
when reading IR.
**Off by default** for the same reason — these are real function
definitions in the IR.
Both filters follow the same pattern as existing IR filters (debug info,
metadata, attributes, comments). Unit tests added in
`llvm-ir-parser-tests.ts` covering filter-on, filter-off, and
preservation of unaffected lines.

## Summary
- When multiarch compilers (Rust, Zig, etc.) target a non-host
architecture (e.g. `--target=aarch64-unknown-linux-gnu`), GNU `objdump`
fails because it cannot disassemble foreign-arch binaries, producing
`<No output: objdump returned 1>`
- Adds a `llvmObjdumper` config property that switches to `llvm-objdump`
when the compilation targets a non-x86 instruction set, since
`llvm-objdump` can auto-detect the target architecture from the binary
itself
- All multiarch compilers benefit from this generically via
`BaseCompiler.getObjdumperForResult()` — no per-compiler special-casing
needed
## Changes
- **`types/compiler.interfaces.ts`** — Add `llvmObjdumper` to
`CompilerInfo`
- **`lib/compiler-finder.ts`** — Read `llvmObjdumper` from config
- **`lib/base-compiler.ts`** — Add `getObjdumperForResult()` method and
refactor `objdump()` to use it
- **`etc/config/rust.defaults.properties`** — Set
`llvmObjdumper=llvm-objdump`
- **`etc/config/zig.defaults.properties`** — Set
`llvmObjdumper=llvm-objdump`
- **`test/objdumper-tests.ts`** — Add 6 tests for cross-architecture
objdumper selection
## Test plan
- [x] `npm run ts-check` passes
- [x] `npm run lint` passes
- [x] All related tests pass (301 tests across 27 files)
- [x] Smoke test: configure a Rust compiler with
`--target=aarch64-unknown-linux-gnu` and verify `llvm-objdump` is used
instead of GNU `objdump`
Fixes#5593
## Summary
- Fix externalparser not working with prediscovered compilers (e.g.,
MicroPython)
- The `externalparser.props` function was lost during JSON
serialization, causing `exe` path to be undefined
- Now stores `exe` and `args` directly on the externalparser object
- Removes the unused `props` function pattern from externalparser
- Adds proper TypeScript typing for externalparser
- Improves error messages to include compiler ID
- Adds delay before process.exit to allow Loki logs to flush
## Test plan
- [x] TypeScript type check passes
- [x] Linter passes
- [x] Unit tests pass
- [ ] Deploy to staging and verify MicroPython compilers work

## What
Adds support for seeing Yul (Solidity IR) as intermediate output when
compiling Solidity.
This PR also enables that view for the Resolc compiler.
### Main Additions
- [x] Support viewing Yul in a supplementary view
- Solidity compilers can enable this by setting
`this.compiler.supportsYulView = true` in the compiler's constructor
- If custom processing of the Yul output or the Yul output filename is
needed, the compiler can override `processYulOutput()` or
`getYulOutputFilename()`
- [x] Enable the Yul view for Resolc
- [x] Implement a Yul backend option for filtering out debug info from
the output
### Notes
Source mappings are currently not handled for Yul -> Solidity.
## Overall Usage
### Steps
* Choose Solidity as the language
* Choose a Resolc compiler
* View intermediate results:
* Yul
* (Hide/show debug info by toggling "Hide Debug Info" in the Yul view
filters)

Close#5530. Infra:
https://github.com/compiler-explorer/infra/pull/1711. Previous work by
@siboehm at #5531
## Summary
This pull request introduces support for the
[Triton](https://github.com/triton-lang/triton) language, a Python-based
DSL for writing highly efficient GPU kernels.
- [x] **New Language Support**: I've added comprehensive support for the
Triton programming language, allowing users to compile and inspect
Triton kernels within Compiler Explorer. (c.f.,
`lib/compilers/triton.ts`)
- [x] **Python Wrapper for Compilation**: A new Python wrapper script
(`triton_wrapper.py`) has been introduced to manage Triton compilation,
patching its behavior to dump compiled kernels and intermediate
representations without requiring actual execution, and consolidating
the output for Compiler Explorer.
- [x] **Device Assembly View**: Enables viewing of generated device
assembly code (e.g., PTX, AMDGCN) and various intermediate
representations (MLIR, LLVM IR) produced by the Triton compiler.
- [x] **MLIR Parsing**: New parsers (`asm-parser-mlir.ts` and
`mlir-pass-dump-parser.ts`) have been added to correctly interpret and
display MLIR assembly and optimization pass dumps, including source
location information.
- [x] **Multi-Version & Multi-Backend Support**: Painstakingly includes
all 8 versions (from 2.2.0 to 3.3.1) of Triton that supports Python
3.12. Supports both CUDA and HIP backend for Triton 3.

/>
## Implementation Details (and Notes for Reviewers)
- For Device Assembly View, I Implemented `MlirAsmParser` for parsing
MLIR assembly. Technically MLIR is not an assembly language, but there
is no better choice to make the source line map work w/ device view.
- I Implemented `MlirPassDumpParser` for processing MLIR optimization
pass dumps. I tried to subclass `LlvmPassDumpParser`, but they turn out
to be too different to worth doing it.
- `LlvmPassDumpParser` made some assumptions that do not hold true for
MLIR passed. Some effort is put to make sure that the passes are
properly diff-ed, since some passes can run multiple times and also
sometimes pass can be nested (i.e., some number of `before`s followed by
some number of `after`s)
- A lot of effort is put into `patch_triton` to make sure that the we
only compile the kernel without actually running it, and that needs to
work across all the versions we support.
## Steps to Run Locally
1. Clone https://github.com/ShawnZhong/compiler-explorer-infra.git
2. Install Triton to `/opt/compiler-explorer/triton`:
```sh
$ cd compiler-explorer-infra
$ ./bin/ce_install install triton
$ ls /opt/compiler-explorer/triton
# v2.2.0 v2.3.0 v2.3.1 v3.0.0 v3.1.0 v3.2.0 v3.3.0 v3.3.1
```
3. Clone https://github.com/ShawnZhong/compiler-explorer.git and
checkout branch `triton`
4. Run Compiler Explorer
```sh
make EXTRA_ARGS='--language triton' dev
```
5. Enjoy

- latest biome, and fix its configuration
- fixes "static" content to be globally configured too (instead of
per-line)
- fixes issues:
- imports fixed up
- `Date.now()` vs `+new Date()`
- some unused things `_` prefixed
After discussion with the team, turned off the unused parameter warning.
- Removes `rootDirs` so all imports will be relative in the frontend
- Updates (and unifies) imports to be `../types/...` etc instead of
relying on "types" being in the rootDir for the frontend.
- Fixes one type that was being picked up from `lib` in the frontend.
- Adds a precommit hook to check in future
Paves the way to writing _unit_ tests for the frontend for the subset of
the frontend code we can import from `node` (which might be a lot of
it!)
This PR adds support for the Mojo programming language.
Explicitly tested viewing the generated assembly, LLVM IR, and running
the generated executable.
This adds support for the [Sail
language](https://github.com/rems-project/sail) - a DSL for defining
ISAs.
It's not quite ready but I need some help. These are the main remaining
issues:
1. When you "link to binary" it does disassemble the binary properly,
but the syntax highlighting and line numbers are broken.
2. If you try to execute the code without a `function main() -> unit =
...` then it gives this error in the compiler output:
```
Internal Compiler Explorer error: Error: spawn /tmp/compiler-explorer-compiler2025025-31052-c8gern.pf8t/model.c EACCES
at ChildProcess._handle.onexit (node:internal/child_process:285:19)
at onErrorNT (node:internal/child_process:483:16)
at process.processTicksAndRejections (node:internal/process/task_queues:82:21)
Compiler returned: -1
```
This is weird - it should give a linker with an undefined reference to
`zmain`.
3. Sail compiles to C, and then I added extra steps to compile that to
binary (if you select `Execute the code`), but as you can see I had to
move the binary back over the C file, so in this case `model.c` is
actually an ELF file. It works but that seems very weird. There is a
`getExecutableFilename()` method I could override, but doing that seems
to make it even more confused.
4. I also had to have a fake flag for `binary` because the `filters`
don't seem to get set correctly when passed to `runCompiler()`. E.g.
`buildExecutable()` doesn't pass them at all. Not sure what is going on
there. Seems to work though.
Any help appreciated!
PS: Sail is a cool language. It has lightweight dependent type for
integers and bit vectors, which I haven't demonstrated in the examples
yet, but they're neat.

This fork provides a rudimentary way of using Coccinelle within Compiler
Explorer.
In the left window one can edit either C or C++ code, and within
preprocessor ifdefs, one can write a semantic patch for Coccinelle.
The right window will display the transformed code.
A coccinelle on infra is not yet done.
Any distribution-based coccinelle would do, for the moment.
If you like it, this close#6999 .

- Add initial support for Numba compilation: asm, demangling, execution
Numba wraps Python functions in `Dispatcher` objects. Each dispatcher
contains zero or more compiled argument-type-indexed overloads of its
function. We import the user's code as a module, and emit the code from
all overloads of all dispatchers that the module publicly exposes.
Name mangling is odd in Numba. It uses a similar mangling syntax to C++,
but also encodes non-symbol (`r"[^a-z0-9_]"`) characters as `_%02x`.
This encoding yields valid identifier names, so it is not strictly
invertible. Here, I have hard-coded some replacements to decode some
common cases at the cost of possible clashes with ugly user-defined
names.
Screenshot captured via `make dev EXTRA_ARGS="--debug --language numba"`
## To do
- [x] Answer questions of #5591.
- [x] Acquire a python environment.
- [ ] Automatically run the python test?
Locally, I have installed a virtual environment with python 3.12.3 with
```shell
path/to/python -m venv venv_numba
path/to/venv_numba/bin/python -m pip install numba==0.61.0 scipy>=0.16
```
and configured its use with
```properties
# compiler-explorer/etc/config/numba.local.properties
compilers=&numba
defaultCompiler=numba_0_61_0
group.numba.compilers=numba_0_61_0
group.numba.baseName=Numba
compiler.numba_0_61_0.exe=/path/to/python3.13
compiler.numba_0_61_0.semver=0.61.0
```
I run this python-side test file with
```python
path/to/venv_numba/bin/python -m unittest etc/scripts/test_numba_wrapper.py
```

[ORCA/C](https://github.com/byteworksinc/ORCA-C) is a C compiler that
natively runs on and targets the Apple IIGS. ORCA/C and the programs it
generates can be run on modern Linux systems by using an emulation tool
called [Golden Gate](https://goldengate.gitlab.io).
This adds support for ORCA/C (run via Golden Gate) in Compiler Explorer.
It uses its own assembly format and objdumper (provided by Golden Gate),
so support for those is added. An extra configuration option was also
added to support execution via an emulator, bypassing the usual check
that executables can run natively. Asm docs for the WDC 65C816 processor
were also added.
ORCA/C and Golden Gate are not Free Software, but their rights holders
have given permission for them to be used on Compiler Explorer. Tarballs
for them can be supplied privately. See infra PR:

Libraries were being fetched from wrong URL (on startup);
`Fetching remote libraries from
https://godbolt.org:443/api/libraries/c++`
Ended up refactoring a bunch of things to get some unittesting going on
I did not test actual startup and compilation with CE, I might have
broken something. (but @mattgodbolt tested and it looked great)
- Uses strings across the board in the UI part (no functional change
here from before; all state is the same as it was before).
- Sends _arrays_ in the POST, using the same `splitArguments` code as
the backend.
- Backend _still supports_ strings (though doesn't advertise), also
using same `splitArguments`.
- Moves `splitArguments` into common utils, and rephrases to avoid
unnecessary use of underscore and ES2021+ code.
Tested locally:
- with both old and new client code (ran new backend and old webcode to
show sending strings still works)
- with creating and removing tool windows (checked with `ldd` locally)
- with various strings on the client `moo foo "this is bad" #moo` and
even "error" things like `this is "badger` (with a missing close quote).
All works as you'd expect
Happy to break the "move the splitArguments" code into a separate PR if
that'd be easier to review separately.
Fixes#7195
Does some winter cleaning on the site-template stuff :)
1. Migrated away from the custom conf format to plain old yaml
2. Made the images and image files match with the name from the yaml
file. (It's not a problem to have spaces in file paths, nor urls so I
don't see why we shouldn't)
3. Updated the relevant documentation
There is a small breakage in the api response for the meta field. It now
returns `{"screenshot_dimensions":{"width":1000,"height":800}}` which I
believe is a lot more useful than
`{"meta.screenshot_dimensions":"1000x800"}`
Besides, I don't believe this endpoint has any third-party consumers
that rely on the metadata since it's a rarely known feature anyways
This is the first PR in API consistency with more to come:
1. The source API urls have been properly defined with
`/source/:source/list` and `/source/:source/load/:language/:filename`
- These used to be two API endpoints mushed together into one `handle()`
function. They are now separate
- While it may appear from the tests that this is an API breakage,
there's currently no way to have the source API spit out responses for
stuff like `/source/moose/load/Grunkle`.
2. The frontend code calling the list api now has shared types
3. Code has been migrated to `/lib/handlers/api/source.ts`
- I've moved code here, because I would like to separate the stuff
that's under the API and the stuff that isn't (e.g., healthcheck)
- The source endpoint is currently not under /api, but I believe it
makes sense to move it.
4. GitHub is terrible at showing the diff, but the `browser.ts` file has
been removed, since it's never actually used. Our frontend only calls
`/source/builtin/...` and it never had any entries. Besides, the type
used on the frontend for the locally stored stuff is different...
Hello! I'm a big fan of Godbolt and use it regularly to test gas
optimizations in Solidity. However, to this day, there is no support for
Vyper, the second most popular language targeting the EVM, related issue
#4165. We at Statemind.io thought that adding Vyper support would
greatly benefit developers and security researchers, so here is our
attempt to get it working :)
This PR **is not ready** for merging, as `vyper.defaults.properties` and
`vyper.amazon.properties` are not yet defined. I have a few questions to
clarify how to integrate it on the public instance and infrastructure
repository:
Because Vyper compiler is basically a python module, I've found success
in testing multiple versions via separate `venv` environments. In my
local tests `vyper.local.properties` was the following:
```INI
compilers=vyper
compilerType=vyper
versionFlag=--version
compiler.vyper.exe=/opt/research/godbolt/venv/bin/vyper
compiler.vyper.isSemVer=true
compiler.vyper.instructionSet=evm
compiler.vyper.options=--optimize none
```
The versions tested are the latest major Vyper release 0.4.0, along with
0.3.10 and earlier 0.3.xx releases.
It appears that there is support for running python in a virtual
environment in the infra repository:
https://github.com/compiler-explorer/infra/blob/main/bin/lib/installable/python.py
However, I've had difficulties getting started with it and would greatly
appreciate any assistance. Thank you!
1. Gives a proper type to the metadata
2. Fixes a typo in `screenshot_dimentions`
3. Removes home-made partition function in favor of underscore
4. Reads file asynchronously (and consequently rest of API is async)
5. Strips the `https://godbolt.org/#` from each entry in the config file
As an added benefit this should also cut some startup time reading this
file before it's used :)
