Using weak symbols in static libraries has other semantics than in shared ones, i.e. with a static library the symbol lookup stops at the first symbol – even if it is just weak and an object file with a strong symbol is also included in the library archive. On Linux, the linker option --whole-archive changes that behavior. [10]
Although this will not work in all cases, for example when calling the wrong subroutine, it is the easiest way to find the problem if the program uses the incorrect results of a bad mathematical calculation.
This is a list of operators in the C and C++ programming languages.. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.
The Objective-C runtime maintains information about the argument and return types of methods. However, this information is not part of the name of the method, and can vary from class to class. Since Objective-C does not support namespaces, there is no need for the mangling of class names (that do appear as symbols in generated binaries).
Each symbol type is represented by a single character. For example, symbol table entries representing initialized data are denoted by the character "d" and symbol table entries for functions have the symbol type "t" (because executable code is located in the text section of an object file). Additionally, the capitalization of the symbol type ...
The Global Offset Table is represented as the .got and .got.plt sections in an ELF file [5] which are loaded into the program's memory at startup. [5] [6] The operating system's dynamic linker updates the global offset table relocations (symbol to absolute memory addresses) at program startup or as symbols are accessed. [7]
Symbolic execution is used to reason about a program path-by-path which is an advantage over reasoning about a program input-by-input as other testing paradigms use (e.g. dynamic program analysis). However, if few inputs take the same path through the program, there is little savings over testing each of the inputs separately.
