NAME¶

patscc - ATS2 compiler frontend

SYNOPSIS¶

patscc [options] files...

DESCRIPTION¶

patscc is a frontend to the Postiats compiler patsopt for the ATS2 language.

OPTIONS¶

patscc has a command-line option syntax in the style of gcc and accepts all the same options, many of them being passed directly to the gcc backend. Here are summarized the non-gcc options.

-atsccomp <command>

Specify the name of the C compiler on the command line. Otherwise, use environment variable ATSCCOMP or the default. See further details on environment variables.

-cleanaft

Clean up incidental generated C files after compilation finishes.

--compile, -ccats

Only compile the given ATS source files into C files.

-DATS <name>[=<value>], -DDATS <name>[=<value>]

Define a name/value macro toplevel value in ATS. -DDATS also passes this option to the C compiler.

-IATS <path>, -IIATS <path>

Add a path to search for ATS files when doing static and dynamic loads. -IIATS also passes this path to the C compiler.

-fsats <file>, -fdats <file>

These indicate that the following file is a SATS or a DATS file. Unnecessary if standard filename extensions .sats or .dats are used.

--gline

Place line pragma information based on ATS source in the generated C code.

--typecheck, -tcats

Typecheck the given ATS source files, but go no further.

--version, -vats

Show ATS2/Postiats version and gcc version.

ENVIRONMENT VARIABLES¶

PATSCCOMP, ATSCCOMP

Use the value of this environment variable as the command name of the C compiler. The default is gcc -D_XOPEN_SOURCE -I${ATSHOME} -I${ATSHOME}/ccomp/runtime -L${ATSHOME}/ccomp/atslib/lib

PATSHOME, ATSHOME

Use the value of this environment variable as the path to the ATS library installation. The default is distribution-specific.

PATSOPT, ATSOPT

Use the value of this environment variable as the command name of the ATS compiler. The default is patsopt.

EXAMPLES¶

patscc -o test -O3 test.dats

Compile test.dats to an executable named test. Tell gcc to use the third level of optimization.

patscc -tcats test.dats

Typecheck test.dats only.

patscc -ccats test.dats

Compile to C file test_dats.c only.

patscc -o test.o -c test.dats -cleanaft

Compile test.dats to an object file named test.o, and delete intermediate C file.
