e-acsl-gcc.sh - Man Page
instrument and compile C files with E-ACSL
Synopsis
e-acsl-gcc.sh [ options ] files
Description
e-acsl-gcc.sh is a convenience wrapper for instrumentation of C programs using the E-ACSL Frama-C plugin and their subsequent compilation using the GNU compiler collection (GCC).
Options
- -h, --help
show a help page.
- -c, --compile
compile the generated and the original (supplied) sources. By default no compilation is performed.
- -D, --rt-debug
enable runtime debug features, i.e., compile unoptimized executable with assertions and extra checks.
- --no-trace
disable stack trace reporting in debug mode
- -V, --rt-verbose
output extra messages when executing generated code
- -X, --instrumented-only
do not compile original code. Has effect only in the presence of the -c flag.
- -C, --compile-only
compile the input files as if they were generated by E-ACSL.
- -d, --debug=<N>
pass a value to the Frama-C -debug option. By default the -debug flag is unused.
- -v, --verbose=<N>
pass a value to the Frama-C -verbose option. By default the -verbose flag is unused.
- --check
check integrity of the generated AST (mostly useful for developers).
- -o, --ocode=<FILE>
output the E-ACSL instrumented code to <FILE>. Defaults to a.out.frama.c.
- -O, --oexec=<FILE>
output the code compiled from the uninstrumented sources to <FILE>. The executable compiled from the files generated by E-ACSL is appended the .e.acsl suffix. Unless specified, the names of the executables generated from the original and the modified programs are a.out and a.out.e-acsl respectively.
- --oexec-e-acsl=<FILE>
name of the executable file generated from the E-ACSL-instrumented file. Unless specified, the executable is named as inidicated by the --oexec option.
- -f, --frama-c-only
run input source files through Frama-C without E-ACSL instrumentations.
- -E, --extra-cpp-args=<FLAGS>
pass additional arguments to the Frama-C preprocessor.
- -L, --frama-c-stdlib
use the Frama-C standard library instead of a system-wide one.
- -M, --full-mtracking
maximize memory-related instrumentation.
- --concurrency
enable concurrency support.
- --temporal
enable checking for temporal memory errors in \valid and \valid_read predicates.
- --weak-validity
enable notion of weak validity. By default expression (p+i), where p is a pointer and i is an integer offset is deemed valid if both addresses p and (p+i) belong to the same allocated block. With weak validity (p+i) is valid if the memory location which address is given by expression (p+i) is allocated.
- --validate-format-strings
enable built-in detection of format-string vulnerabilities.
- --libc-replacements
replace some of the unsafe LIBC functions (e.g., strcpy, memcpy) with RTL alternatives that include internal runtime error checking.
- -g, --gmp
always use GMP integers instead of C integral types. By default the GMP integers are used on as-needed basis.
- --mbits=<BITS>
architecture to compile to. Valid arguments are 16, 32 or 64. Default to the architecture of the current environment. This option is used to select the machdep when calling Frama-C, and to pass the corresponding -m16, -m32 or -m64 flag to the compiler.
- -l, --ld-flags=<FLAGS>
pass the specified flags to the linker.
- -e, --cpp-flags=<FLAGS>
pass the specified flags to the preprocessor at compile-time. For instrumentation-time preprocessor flags see --extra-cpp-args option.
- -q, --quiet
suppress any output except for errors and warnings.
- -s, --logfile=<FILE>
redirect all output to a given file.
- -F, --frama-c-extra=<FLAGS>
pass an extra option to a Frama-C invocation.
- -a, --rte=<OPTSTRING>
annotate a source program with assertions using a run of an RTE plugin prior to E-ACSL. OPTSTRING is a comma-separated string that specifies the types of generated assertions. Valid arguments are:
signed-overflow - signed integer overflows.
unsigned-overflow - unsigned integer overflows.
signed-downcast - signed downcast exceeding destination range.
unsigned-downcast - unsigned downcast exceeding destination range.
mem - pointer or array accesses.
float-to-int - casts from floating-point to integer.
div - division by zero.
shift - left and right shifts by a value out of bounds.
pointer-call - annotate functions calls through pointers.
all - all of the above.- -A, --rte-select=<OPTSTRING>
restrict annotations to a given list of functions. OPTSTRING is a comma-separated string comprising function names.
- --zone-sizes=<NAME1:SIZE1,...,NAMEN:SIZEN>
set the size (in MB) of the given zones.
Valid zone names are:
stack - stack shadow space
heap - heap shadow space
tls - TLS shadow space
thread-stack - thread stack shadow space- -k, --keep-going
continue execution after an assertion failure
- --free-valid-address
trigger failure if a NULL-pointer is used as an input to free function
- --fail-with-code=<NUMBER>
on assertion failure exit with the given integer code intead of raising an abort signal
- --assert-print-data
print data contributing to the failed assertion along with the runtime error message
- --no-assert-print-data
do notprint data contributing to the failed assertion along with the runtime error message
- --external-assert=<FILE>
the filename that contains your own implementation of __e_acsl_assert
- --external-print-value=<FILE>
the filename that contains your own implementation of __e_acsl_print_value
- -m, --memory-model=<model>
memory model (i.e., a runtime library for checking memory related annotations) to be linked against the instrumented file.
Valid arguments are:
bittree - memory modelling using a Patricia trie.
segment - shadow based segment model.By default the Patricia trie memory model is used.
- --print-mmodels
print the names of the supported memory models
- -I, --frama-c=<FILE>
the name of the Frama-C executable. By default the first frama-c executable found in the system path is used.
- --e-acsl-share=<DIR>
the name of the E-ACSL share directory. If not provided, it is computed from your setting.
- -G, --gcc=<FILE>
the name of the GCC executable. By default the first gcc executable found in the system path is used.
- --then
separate with a -then the first Frama-C options from the actual launch of the E-ACSL plugin.
- --then-last
separate with a -then-last the first Frama-C options from the actual launch of the E-ACSL plugin.
- --e-acsl-extra=<OPTS>
add <OPTS> to the list of options that will be given to the E-ACSL analysis. Only useful when --then is in use, in which case <OPTS> will be placed after the -then on Frama-C's command-line. Otherwise, equivalent to --frama-c-extra.
- --ar=<FILE>
the name of the AR executable. Only relevant with --dlmalloc-from-sources. By default the first ar executable found in the system path is used.
- --ranlib=<FILE>
the name of the RANLIB executable. Only relevant with --dlmalloc-from-sources. By default the first ranlib executable found in the system path is used.
- --with-dlmalloc=<FILE>
use <FILE> instead of distributed dlmalloc library.
- --dlmalloc-from-sources
compile and use dlmalloc library from sources instead of using the distributed library. Incompatible with --with-dlmalloc.
- --dlmalloc-compile-only
do not instrument or compile code, only compile dlmalloc library from sources. Implies --dlmalloc-from-sources and incompatible with --with-dlmalloc.
- --dlmalloc-compile-flags=<FLAGS>
compile dlmalloc library with <FLAGS> compile flags. Default to -O2 -g3. Unused if --dlmalloc-from-sources or --dlmalloc-compile-only isn't used.
- --odlmalloc=<FILE>
output compiled dlmalloc library to <FILE>. Unused if --dlmalloc-from-sources or --dlmalloc-compile-only isn't used.

e-acsl-gcc.sh --memory-model=bittree -C gen_foo.c
