  2. How can i get inline assembly to work in dev-cpp in can get it to work in msvcpp but not in dev-cpp. Any help would be greatly appreciated.

I am trying to find a very basic C inline x86-64 assembly example, similar to this: a Simple 'Hello World' Inline Assembly language Program in C/C. First, the authors describe basic usage syntax for inline assembly (inline asm) embedded within C and C programs. Then they explain intermediate concepts, such as addressing modes, the clobbers list, and branching stanzas, as well as more advanced topics, such as memory clobbers, the volatile attribute, and locks are discussed for those who want to use inline asm in multithreaded applications. Assembly speed = C as C is compiled into assembly code. With handwritten assembly, you might be able to make the routine more efficient than the C compiler does. On most modern systems though, the results aren't noticeable. The difference is that C is much faster development time while assembly is much better for custom processors. Inline assembly is used for speed, and you ought to believe me that it is frequently used in system programming. We can mix the assembly statements within C/C programs using keyword asm. Inline assembly is important because of its ability to operate and make its output visible on C/C variables. GCC Inline Assembly Syntax.

asm-declaration gives the ability to embed assembly language source code within a C++ program. This declaration is conditionally-supported and implementation defined, meaning that it may not be present and, even when provided by the implementation, it does not have a fixed meaning.

[edit]Syntax

asm (string_literal);

[edit]Explanation

The string_literal is typically a short program written in assembly language, which is executed whenever this declaration is executed. Different C++ compilers have wildly varying rules for asm-declarations, and different conventions for the interaction with the surrounding C++ code.

As other block declarations, this declaration can appear inside a block (a function body or another compound statement), and, as all other declarations, this declaration can also appear outside a block.

[edit]Examples

Demonstrates two kinds of inline assembly syntax offered by the GCC compiler. This program will only work correctly on x86_64 platform under Linux.

Output: Hello kitty cooking games free download.
