Summary

On this page we are collecting the current state of the TCG Interpreter (= TCI) implementation for Qemu.

TCG (Tiny Code Generator) is a code generator which translates code fragments (basic blocks) from target code (any of the targets supported by QEMU) to a code representation which can be run on a host. This allows running QEMU on any 32 or 64 bit host (while the QEMU without TGC only supports the most important host architectures like x86, arm, mips, ppc, s390, sparc).

See http://repo.or.cz/w/qemu/ar7.git/blob_plain/HEAD:/tcg/bytecode/README for more details.

Status

Old versions of the TCG interpreter were already published on the mailing list (qemu-devel). The latest version which includes many fixes and improvements still has to be published before it can be committed to the official QEMU release.

Tested on x86 (32 and 64 bit), arm, mips (emulated) and ppc (emulated) hosts running Debian GNU Linux or MS Windows.
Tested with i386, x86_64, mips and other emulations in system and user mode.

TODOs

Publish and discuss latest code on qemu-devel.
Add better disassembler.
Run more tests (especially with new hosts).
Commit code to official QEMU.

Code

We are currently keeping the code in a separate git repository.
