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.


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