WebThis is useful on x86 and not so much on ARM, because x86 overloads mnemonics with many operand types. For example, in this code: int add(int a, int b) { asm("addl%1, %0": "+r" (a): "rm" (b)); return a; } This is one way the compiler could choose to satisfy the rconstraint: add: // Per x86_64 System V calling convention: WebApr 8, 2024 · Jumping out of an inline asm needs special handling. There is extra syntax for it: asm goto. Briefly, your jump should look like this: __asm goto("B %l0" : : : : MYJUMP); Try on godbolt. This compiles to a simple b label. I didn't test it but the generated asm looks "obviously correct".

The GNU Assembler uses the same syntax for all of the many processor architectures that it supports. Webcached in registers across the assembler instruction. You can put multiple assembler instructions together in a single ‘asm’ template, sepa-rated either with newlines (written as ‘\n’) or with semicolons if the assembler allows such semicolons.
