Why do my MIPS crosscompiler works like this for NOT operation?
- by Mazicky
Hello,
I setup my crosscompiler for making MIPS instructions.
And it compiles C code well.
but I found a weird thing for NOT operations.
if i make code like
int a;
func(!a);
and i studied MIPS instructions with text book that says
"MIPS converts NOT operation to 'nor with zero'"
So i thought it would converted like
nor a a $zero
but my compiler converts
xori a a 0x0
sltu a 1
///////////////////////////////////////
i compiled the code with 'myaccount mipsel-unknown-linux-gnu-gcc -S myfilename.c'
and it makes myfilename.s file..
what am i missing??
