The SymChk.exe utility can be used to verify symbols and to build a local symbol cache in a convenient, supposedly non-invasive way. This utility is included with the Debugging Tools for Windows. Visual Studio 2005 and later can be set up to use the Microsoft Symbol Server. [1] The symbol server technology is built into Debugging Tools for Windows.
The term dead code has multiple definitions. Some use the term to refer to code (i.e. instructions in memory) which can never be executed at run-time. [1] [2] [3] In some areas of computer programming, dead code is a section in the source code of a program which is executed but whose result is never used in any other computation.
Program database (PDB) is a file format (developed by Microsoft) for storing debugging information about a program (or, commonly, program modules such as a DLL or EXE).PDB files commonly have a .pdb extension.
In the C language, the POSIX function chdir() effects the system call which changes the working directory. [11] Its argument is a text string with a path to the new directory, either absolute or relative to the old one. Where available, it can be called by a process to set its working directory. There are similar functions in other languages.
Construction of pruned SSA form uses live-variable information in the Φ function insertion phase to decide whether a given Φ function is needed. If the original variable name isn't live at the Φ function insertion point, the Φ function isn't inserted. Another possibility is to treat pruning as a dead-code elimination problem. Then, a Φ ...
An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been declared by that code. [1] In some programming languages, an implicit declaration is provided the first time such a variable is encountered at compile time. In other languages such a usage is considered to be sufficiently ...
Several macros affect the definitions made by windows.h and the files it includes. UNICODE – when defined, this causes the generic text datatype TCHAR to be a synonym of WCHAR instead of CHAR, and all type-generic API functions and messages that work with text will be defined to the -W versions instead of the -A versions.
Several compilers support variable-argument macros when compiling C and C++ code: the GNU Compiler Collection 3.0, [4] Clang (all versions), [8] Visual Studio 2005, [6] C++Builder 2006, and Oracle Solaris Studio (formerly Sun Studio) Forte Developer 6 update 2 (C++ version 5.3). [9] GCC also supports such macros when compiling Objective-C.
