This is a project to develop a compiler for Tcl that produces native code. It does this by translating Tcl code into bytecode, then into quadcode (hence the project's name). That quadcode is analysed and optimized, then translated into LLVM Intermediate Representation, from which native code is issued.
This requires Tcl 8.6, and llvmtcl.
Write some procedures. Load the code in
codegen.tcl in this directory (note that this is not yet a proper
package). Now you have the LLVM command:
LLVM configure options...
Configures LLVM. Useful options are -debug, -opt and -time.
- -debug boolean -- Whether to print debugging information. Off by default.
- -opt int -- Number of optimization rounds to run.
- -time int -- The level to perform timing analysis at. Level 0 turns it off. Level 1 is coarse-grained. Level 2 is detailed.
LLVM optimise procs...
Compiles each of the listed procedures (each name is a separate argument). This is the core of this project. The collection of procedures will become a single package (in a Tcl load sense) that is compiled. Note that you can use command globs as well; internally, everything is passed through info commands.
Returns the LLVM IR generated from the most recent compilation, taken at the point where the IR was about to be fed into the optimizer.
Returns the LLVM IR generated from the most recent compilation, taken after the code was optimized. This is the code that is actually used to drive native code issuing.
If you want to just test-drive the code, check out the
script in this directory. It's our current driver and exercises most
of the currently-implemented features. There's also a
that is a cut-down version.
