Webb[llvm-dev] [RFC] 检查内联汇编的有效性. 228 // 内联 asm 操作数映射到多个 SDNode / MachineInstr 操作数。229 // 第一个操作数是描述 asm 操作数的立即数,低 230 // 位是那种:实际上,关于 asm!,很长时间以来就知道它不太可能按原样稳定 (最初是围绕 LLVM 的内联 asm 功能的一个非常薄的包装器)。 Webb18 jan. 2024 · On x64, (%rax, %edx, 4) is not a legal combination. Consult the processor manual for a list of valid addressing modes. My guess is that you meant (%rax, %rdx, 4). 其他推荐答案. Most likely cause of your problem is the use of an explicit 32bit integer type in the %3 operand. You haven't shown the constraints list for your inline assembly.

It can be used to embed handwritten assembly in the assembly output generated by the compiler. Generally this should not be necessary, but might be where the required performance or timing cannot be otherwise achieved. brainerd movies 10 at westgate

WebbClosed 5 years ago. The x86 assembler language has had to change as the x86 processor architecture has changed from 8bit to 16bit to 32bit and now 64bit. I know that in 32bit assembler register names (EAX, EBX, etc.), the E prefix for each of the names stands for Extended meaning the 32bit form of the register rather than the 16bit form … Webb24 nov. 2012 · Constraints are used when you tell GCC to allocate registers for insn operands, the constraints define the acceptable register class from which to draw registers. The clobbers, on the other hand, tell GCC about registers, which are modified by the insns, in the cases where it's not evident from the input/output constraints, for … Webb如果可能的话,我试图找到一种通用的方法来进行32位到64位的转换,这种转换可以在任何使用正则表达式的32位程序上完成(这样就可以实现自动化)。. 我知道不存在通用的解决方案(64位代码可能比32位代码占用更多的空间,消耗更多. 我正在尝试在Linux中使用 ... brainerd mn vacation
