GCC MIPS-32调用约定/堆栈帧定义 [英] GCC MIPS-32 Calling Conventions / Stack Frame Definition

问题描述

对于MIPS-32处理器体系结构，似乎没有明确的标准化堆栈帧和C语言调用约定（注册表使用等）。也就是说，它似乎完全取决于汇编/编译器工具链来定义自己的堆栈帧和调用约定。我一直在努力寻找关于GCC编译器用于MIPS-32指令集的约定的明确参考。我特别在Cygwin上使用GCC交叉编译器，该编译器针对在eCos开源内核的嵌入式环境中使用的MIPS-32内核。

任何引用定义关于这个领域的GCC for MIPS-32的文档将不胜感激。

解决方案

你说的对，这有点乱并且记录不完整。我会建议：

• http://math-atlas.sourceforge.net/devel/assembly/mipsabi32.pdf
• 看MIPS Runby Dominic Sweetman

检查由编译器生成的反汇编代码，以检查是否与上述引用有出入。

There appears to be no definitive standardized stack frame and C language calling conventions (register usage and such) for the MIPS-32 Processor Architecture. That is, it appears to be completely up to the assembler/compiler tool chain to define their own stack frame and calling conventions. I've struggled to find a definitive reference of what conventions the GCC compiler uses for MIPS-32 instruction set. I'm specially using GCC cross-compiler on Cygwin that targets a MIPS-32 core being used in an embedded environment on the eCos open source kernel.

Any references to definitive documentation about GCC for MIPS-32 in this area would be appreciated.

解决方案

You are right, this is a bit of a mess and is poorly documented. I would recommend:

• http://math-atlas.sourceforge.net/devel/assembly/mipsabi32.pdf
• "See MIPS Run" by Dominic Sweetman
• Examining disassembled code generated by the compiler to check for discrepancies with the above references.
