goto-cc - Man Page
C/C++ to goto compiler
Synopsis
goto-cc [options]
goto-gcc [options]
goto-ld [options]
goto-as [options]
goto-bcc [options]
goto-armcc [options]
goto-cw [options]
Description
goto-cc reads source code, and generates a GOTO binary. Its command-line interface is designed to mimic that of gcc(1). Note in particular that goto-cc distinguishes between compiling and linking phases, just as gcc(1) does. cbmc(1) expects a GOTO binary for which linking has been completed.
The basename of the file that is used to invoke goto-cc controls which behavior will be emulated. This is typically accomplished by using symbolic links.
goto-cc: invokes the default system compiler as preprocessor and just builds a GOTO binary.
goto-gcc: invokes gcc(1) as preprocessor and builds an elf(5) object file including an additional goto-cc section that holds the GOTO binary.
goto-ld: only performs linking, and also builds an elf(5) object as above.
goto-as: invokes the system assembler as(1) and includes the original assembly source as a string in the output file.
goto-bcc: invokes bcc(1) as preprocessor.
goto-armcc: invokes armcc as preprocessor and enables support for the ARM's C dialect and command-line options.
goto-cw: invokes mwcceppc as preprocessor and enables support for CodeWarrior's C dialect and command-line options.
Options
goto-cc understands the options of gcc(1) plus the following.
- --verbosity N
Set verbosity level to N, which defaults to 1 (only errors are printed). A verbosity of 0 disables all output. Using a verbosity of 2 or greater, or using -Wall enables warnings. Verbosity levels 4, 6, 8, 9, or 10 add increasing amounts of debug information.
- --function name
Set entry point to name.
- --native-compiler cmd
Invoke cmd as preprocessor or compiler.
- --native-linker cmd
Invoke cmd as linker.
- --native-assembler cmd
Invoke cmd as assembler (goto-as only).
- --export-file-local-symbols
Name-mangle and export file-local (aka static) functions. Name mangling prefixes each symbol name by __CPROVER_file_local and the basename of the file. For example,
// foo.c static int bar();
yields a globally visible __CPROVER_file_local_foo_c_bar function. Note that this approach mangles all functions contained in a translation unit. We recommend using crangler(1) as a more configurable alternative.
- --mangle-suffix suffix
Append suffix to exported file-local symbols. Use this option together with --export-file-local-symbols when multiple files of the same base name contain a static function of the same name. If so, use a unique suffix in at least one of the goto-cc invocations used in compiling those files.
- --print-rejected-preprocessed-source file
Copy failing (preprocessed) source to file.
Backward Compatibility
goto-cc will warn and ignore the use of --object-bits, which previous versions processed. This option now instead needs to be passed to cbmc(1).
Environment
All tools honor the TMPDIR environment variable when generating temporary files and directories. goto-cc aims to accept all environment variables that gcc(1) does.
