Originally posted by: billo In a previous post I showed how to use the operand syntax of inline asm to eliminate the need for explicit loads and stores in the asm code. I wound up with an asm like this... asm ( "addi %0,%0, 88 \n" : " +r" (x) : ); ...
Originally posted by: billo The basic premise of inline asm is to be able to write assembly code within your C or C++ program (using asm operands to connect the asm code to the parent program), delegate the translation of that assembly to the compiler and/or the system assembler, and...

Originally posted by: billo This posting concerns outputs which are assigned registers that may overlap with inputs. Consider this inline asm that uses addc and adde in order to accomplish 128 bit arithmetic... asm ("addc %0, %2, %3 \n" "adde %1, %4, %5 \n" : "=r"(xl)...
Originally posted by: billo Hi. This is the first posting in what I hope to be a continuing blog on tips and tricks for inline assembly – a.k.a. asm – which is a way of inserting assembly language into your C and C++ programs. In this blog I won’t be covering basic syntax and semantics ...
Originally posted by: melaniejs 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,...
