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.
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(寄存器使用等)。也就是说,它似乎完全取决于汇编器/编译器工具链来定义自己的堆栈帧和调用约定。我很难找到GCC编译器用于MIPS-32指令集的约定的明确引用。我特意在Cygwin上使用GCC交叉编译器,目标是在eCos开源内核的嵌入式环境中使用MIPS-32内核。
Any references to definitive documentation about GCC for MIPS-32 in this area would be appreciated.
任何有关MIPS-32在该领域的GCC权威文件的提及都将受到赞赏。

You are right, this is a bit of a mess and is poorly documented. I would recommend:
你是对的,这有点乱,而且记录很少。我建议:
- 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.
Dominic Sweetman的“MIPS Run”
检查编译器生成的反汇编代码,以检查与上述引用的差异。

I'm not into MIPS, but maybe this MIPS ABI History reference might help.
我不是MIPS,但也许这个MIPS ABI历史参考可能有所帮助。

Does this reference on MIPS EABI for RedHat Linux help?
