gc-cc

NAME

gc-cc - the Graf-based C compiler

SYNOPSIS

gc-cc [input] [-s <standard>] [-p] [-e] [-i <include>] [-o <output>] [options]

DESCRIPTION

gc-cc compiles C code using the Aro C compiler frontend and the Graf compiler infrastructure. C89 through C23 are supported.

Note that gc-cc is primarily used as a way to field-test the Graf compiler infrastructure; it is not a production-quality C compiler in the same capacity as e.g. GCC or Clang. As such, its option spellings are slightly different than those compilers.

If the input file name is omitted or set to -, then input is read from standard input.

If the -o option is not specified, then the output method is selected according to these rules:

• If the input is read from standard input, then the output is written to standard output.

• If the input is a file name, then the output is written to the same file name but with the extension changed to .gcm.

OPTIONS

• -h, --help: Print usage information and exit.

• -v, --version: Print version information and exit.

• -s, --standard <standard>: Set the C language standard (c23 (default), c17, c11, c99, c89).

• -p, --pedantic: Disable C language extensions.

• -e, --error: Enable treating warnings as errors.

• -d, --define <name[=value]>: Define a macro as if #define was used.

• -u, --undefine <name>: Undefine a macro as if #undef was used.

• -i, --include <include>: Add a preprocessor include search path.

• --isystem <include>: Add a preprocessor include search path and consider it to contain system headers.

• -t, --target <triple>: Set the target triple. Defaults to the host machine's detected triple.

• -c, --cpu <cpu>: Set the target CPU model and features. Defaults to either baseline or native depending on the usage of -t.

• -o, --output <output>: Set the output file name. If set to -, then output is written to standard output.

EXIT STATUS

On success, the exit code will be 0. If an error occurs, the exit code will be non-zero.

ENVIRONMENT

• NO_COLOR: If set to a non-empty value, disables colored diagnostic messages.
