Note the AT&T syntax used by default, which has outputs on the right of the asm instructions. Intel format can be used, which swaps things around. However, most gcc inline asm you will see will stick to AT&T format, so you should get used to seeing it.The above compiles into:.p2align...
Inline Assembly is different in VC++ and gcc. VC uses Intel syntax while gcc uses AT&T syntax. Here we define the difference in syntax of AT&T and Intel's assembly. Source and Destination Ordering In AT&T syntax the source is always on the left, and the destination is always on the right...
In gcc you can use extended asm for telling the compiler what you did in your inline asm code. Like what registers you made dirty. You can even ask compiler to put the value of some variables into some resgisters for you. The Extended Inline Assembly The syntax of extended inline asm is...

A lot of inline assembly in BPF programs uses the pseudo-C syntax, however, so GCC has to support it.这并不是使 GCC 的输出更接近 LLVM 输出的唯一变化;当启用调试信息时,GCC 现在默认产生 BPF 类型格式(BTF)调试信息。它还默认发出伪 C BPF 代码,对此 Marchesi 表示“我整个灵魂都很厌恶”。然而,...
