Refactored out the function flag and its help function to rebuild_goto_start_functions. Used this extracted flag in goto-analyze, symex and CBMC. Added tests that check both goto-analyze and symex when ran with the --function flag actually generate the correct _start function. Also added tests for when it isn't a precompiled binary. Added these new folders to the overal test suite --- regression/Makefile | 2 ++ .../regenerate-entry-function/main.c | 16 ++++++++++ .../regenerate-entry-function/test.desc | 8 +++++ .../regenerate-entry-function/test.desc | 1 - regression/goto-cc-goto-analyzer/Makefile | 32 +++++++++++++++++++ regression/goto-cc-goto-analyzer/chain.sh | 12 +++++++ .../regenerate-entry-function/main.c | 16 ++++++++++ .../regenerate-entry-function/test.desc | 8 +++++ regression/goto-cc-symex/Makefile | 32 +++++++++++++++++++ regression/goto-cc-symex/chain.sh | 12 +++++++ .../regenerate-entry-function/main.c | 16 ++++++++++ .../regenerate-entry-function/test.desc | 8 +++++ .../symex/regenerate-entry-function/main.c | 16 ++++++++++ .../symex/regenerate-entry-function/test.desc | 8 +++++ src/cbmc/cbmc_parse_options.cpp | 2 +- src/cbmc/cbmc_parse_options.h | 4 ++- .../goto_analyzer_parse_options.cpp | 1 + .../goto_analyzer_parse_options.h | 3 +- .../rebuild_goto_start_function.cpp | 2 +- .../rebuild_goto_start_function.h | 6 ++++ src/symex/symex_parse_options.cpp | 2 +- src/symex/symex_parse_options.h | 3 +- 22 files changed, 203 insertions(+), 7 deletions(-) create mode 100644 regression/goto-analyzer/regenerate-entry-function/main.c create mode 100644 regression/goto-analyzer/regenerate-entry-function/test.desc create mode 100644 regression/goto-cc-goto-analyzer/Makefile create mode 100755 regression/goto-cc-goto-analyzer/chain.sh create mode 100644 regression/goto-cc-goto-analyzer/regenerate-entry-function/main.c create mode 100644 regression/goto-cc-goto-analyzer/regenerate-entry-function/test.desc create mode 100644 regression/goto-cc-symex/Makefile create mode 100755 regression/goto-cc-symex/chain.sh create mode 100644 regression/goto-cc-symex/regenerate-entry-function/main.c create mode 100644 regression/goto-cc-symex/regenerate-entry-function/test.desc create mode 100644 regression/symex/regenerate-entry-function/main.c create mode 100644 regression/symex/regenerate-entry-function/test.desc diff --git a/regression/Makefile b/regression/Makefile index 74ae36dd7be..0e791995ec2 100644 --- a/regression/Makefile +++ b/regression/Makefile @@ -6,6 +6,8 @@ DIRS = ansi-c \ cpp \ goto-analyzer \ goto-cc-cbmc \ + goto-cc-goto-analyzer \ + goto-cc-goto-symex \ goto-diff \ goto-gcc \ goto-instrument \ diff --git a/regression/goto-analyzer/regenerate-entry-function/main.c b/regression/goto-analyzer/regenerate-entry-function/main.c new file mode 100644 index 00000000000..6a035127022 --- /dev/null +++ b/regression/goto-analyzer/regenerate-entry-function/main.c @@ -0,0 +1,16 @@ +#include + +int fun(int x) +{ + int i;

Firstly, the function name is transformed to allow simpler function names to be passed in. As such the rebuild_entry_point cannot be responsible for looking up the symbol. This in turn involved a new way of identifying the mode to use (using the existing entry points mode) Secondly, as the lanuages are destroyed after the parsing phase, we must re-provide the message handler as this is used by the entry point generation. Finally, the java_bytecode_entry_point adds a new symbol to the symbol table, so we remove all symbols that are in the scope of the original entry point. --- src/ansi-c/ansi_c_language.cpp | 4 +- src/ansi-c/ansi_c_language.h | 2 +- src/cpp/cpp_language.cpp | 4 +- src/cpp/cpp_language.h | 2 +- .../rebuild_goto_start_function.cpp | 65 +++++++++++++------ .../rebuild_goto_start_function.h | 4 ++ src/java_bytecode/java_bytecode_language.cpp | 8 ++- src/java_bytecode/java_bytecode_language.h | 2 +- src/jsil/jsil_language.cpp | 2 +- src/jsil/jsil_language.h | 2 +- src/util/language.h | 2 +- 11 files changed, 65 insertions(+), 32 deletions(-) diff --git a/src/ansi-c/ansi_c_language.cpp b/src/ansi-c/ansi_c_language.cpp index ce28fa1e70c..70e5226c135 100644 --- a/src/ansi-c/ansi_c_language.cpp +++ b/src/ansi-c/ansi_c_language.cpp @@ -43,11 +43,11 @@ void ansi_c_languaget::modules_provided(std::set &modules) /// function symbol will be added to this table /// \return Returns false if the _start method was generated correctly bool ansi_c_languaget::generate_start_function( - const symbolt &entry_function_symbol, + const irep_idt &entry_function_symbol_id, symbol_tablet &symbol_table) { return generate_ansi_c_start_function( - entry_function_symbol, + symbol_table.symbols.at(entry_function_symbol_id), symbol_table, *message_handler);
