A pair of a word address and an offset within the word is called a wide address (also known as a fat address or fat pointer). (This should not be confused with other uses of wide addresses for storing other kinds of supplemental data, such as the bounds of an array.) The stored offset may be either a bit offset or a byte offset.
Internally, BFD translates the data from the abstract view into the details of the bit/byte layout required by the target processor and file format. Its key services include handling byte order differences, such as between a little-endian host and big-endian target, correct conversion between 32-bit and 64-bit data, and details of address ...
GCC has been ported to more platforms and instruction set architectures than any other compiler, and is widely deployed as a tool in the development of both free and proprietary software. GCC is also available for many embedded systems, including ARM-based and Power ISA-based chips.
POD return values 33–64 bits in size are returned via the EAX:EDX registers. Non-POD return values or values larger than 64-bits, the calling code will allocate space and passes a pointer to this space via a hidden parameter on the stack. The called function writes the return value to this address. Stack aligned on 4-byte boundary. stdcall ...
In the case of the NOP instruction, the second value in the second byte is the "base" register of a combined base register, displacement register and offset address. If the base register is also 0, the branch is not taken regardless of the value of the displacement register or displacement address. NOPR: 2
Branch-and-link instructions store the return address in a special link register separate from the general-purpose registers; a routine returns to its caller with a branch instruction that uses the link register as the destination address. Leaf routines do not need to save or restore the link register; non-leaf routines must save the return ...
On modern Linuxes, information on shell built-in commands can be found by executing help, help [built-in name] or man builtins at a terminal prompt where bash is installed. Some commands, such as echo , false , kill , printf , test or true , depending on your system and on your locally installed version of bash, can refer to either a shell ...
In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a type of intermediate representation (IR) where each variable is assigned exactly once. SSA is used in most high-quality optimizing compilers for imperative languages, including LLVM , the GNU Compiler Collection , and many commercial compilers.
