Several MIPS stubs filled in + factoring
Call return type set in out.c, not impl
ICE for MIPS undefined
MIPS store code + reg_cp
Added ICE for cast
Partial function prologue and epilogue
Use the correct MIPS registers
MIPS asm-gen function prologue is incomplete
MIPS asm-gen function epilogue
Use $zero for 0-loads
MIPS reg swap
MIPS binary operators
MIPS unary operators
Only need one register for deref
Fixed type_ref alteration for *()
MIPS argument passing
Code gen commenting
MIPS tests
MIPS undefined/crash instruction
