The T Programming Language version 0.2.0

T is a C-like, module based programming language designed to be a fresh start, incorporating the good features from C and C++.

This repo is the source code for the T Language Compiler, tlc.

Invoking

tlc accepts up to 2^31 - 2 arguments, which can be either a file name or an option. File names are extension-sensitive. Depending on the options, the compiler may produce an error if it encounters a file it does not recognize, or it may ignore the files it does not recognize with a warning. A list of the options follows.

Options

Note that if a later option conflicts with an earlier option, the later option will apply to all files, even those before the earlier option. Additionally, all arguments after -- are treated as files.

Informational Options

• --help, -h, -?: overrides all other options, displays usage information, and causes the compiler to immediately exit normally.

• --version: overrides all other options, except for --help and its abbreviations, displays version and copyright information, and causes the compiler to immediately exit normally.

Architecture

• --arch=x86_64-linux: sets the target architecture to x86_64 Linux (ELF, System V ABI, SSE2 required, nasm assembly syntax). Default.

Warnings

All warning options have three forms, a -W...=error form, a -W...=warn form, and a -W...=ignore form. These forms instruct the compiler to either produce an error if this particular event is encountered (stopping compilation), produce a warning, or ignore the issue. So, for example, -Wfoo=error makes foo into an error, -Wfoo=warn makes foo into a warning, and -Wfoo=ignore ignores foo.

• duplicate-file: duplicated files given. Defaults to error. If not an error, later files have no effect.

• duplicate-import: duplicated imports in a module. Defaults to ignore. If not an error, later imports have no effect.

• unrecognized-file: unrecognized file extensions. Defaults to error. If not an error, unrecognized files are skipped.

Debug Options

The option --debug-dump can be set to one of the following values:

• --debug-dump=none: default, turns off the data dump

• --debug-dump=lex: dumps the results of the lex phase

• --debug-dump=parse: dumps the results of the parse phase

• --debug-dump=translation: dumps the results of the translate to IR phase

• --debug-dump=blocked-optimization: dumps the results of the blocked IR optimization phase

• --debug-dump=trace-scheduling: dumps the results of the trace scheduling phase

• --debug-dump=scheduled-optimization: dumps the results of the scheduled IR optimization phase

Additionally, the following options can be used:

• --debug-validate-ir: validates IR after any step that changes it

• --no-debug-validate-ir: default, turns off IR validation

Limits

The T compiler will memory map all referenced files. As such, the system must have enough address space to handle the memory mappings.
