/* Assembly stub to invoke _mcount(). Compiler generated code calls
|
|
this stub after executing a function's prologue and without saving any
|
|
registers. It is therefore necessary to preserve a0..a5 as they may
|
|
contain function arguments. To work correctly with frame- less
|
|
functions, it is also necessary to preserve ra. Finally, division
|
|
routines are invoked with a special calling convention and the
|
|
compiler treats those calls as if they were instructions. In
|
|
particular, it doesn't save any of the temporary registers (caller
|
|
saved registers). It is therefore necessary to preserve all
|
|
caller-saved registers as well.
|
|
|
|
Upon entering _mcount, register $at holds the return address and ra
|
|
holds the return address of the function's caller (selfpc and frompc,
|
|
respectively in gmon.c language...). */
