Actually, I'm working with simplescalar and it only supports gcc 2.9.

Hi,
I'm working with GCC 2.7. I think, It doesn't support define_predict.
I define a c function in the mips.c file and add the following lines:
int
new_arith_operand (op, mode)
rtx op;
enum machine_mode mode;
{
if (GET_CODE (op) == CONST_INT)
if(NEW_INT_UNSIGNED (op))
Hi,
I want to limit the size of immediate field of some operation. For example
somehow modify the machine description that the compiler supports only 0-255
for immediate operand.
I also want to change the compiler to the 2-address operand.
do you have any ideas?
I just need some hint
Best Regard
I did what you said, and the same error happened :(

Hi,
I want to exclude all immediate or instruction. I did this by the following
define_insn

(define_insn "iorsi3"
[(set (match_operand:SI 0 "register_operand" "=d,d")
(ior:SI (match_operand:SI 1 "uns_arith
Hi,
I want to exclude XORI from the instruction set of a cpu. I deleted all the
XORI in md file. But when I compiled my program some XORI operation still
exist. how this would be possible?

Hi,
I found an strategy that would solve my problem.
I changed .md with the following paragraph...
(define_expand "blt"
[(set (pc)
(if_then_else (lt:SI (match_dup 1)
gen_conditional_le(rtx comp1, rtx comp2, rtx final_label)
{
printf("my operation called");
emit_insn(gen_ble1(comp1, comp2, final_label));
return TRUE;
}
***
but it didn't work...
I want the following C code is compiled to just one inst
To add "ble" I changed "equality_op" in the header file to have "ble" as a
acceptable operation.but it didn't work. Do u have any idea? I also saw some
functions in the assembler that hand
I have read all the documents, and changed some lines but nothing happened :(

Hi,
I want to change instruction blez to ble. ble compare two registers and jump
to the target address if the condition is true.
thanks in advance,

Dear all,
I'm working on my a gcc compiler for my own written processor with the help
of SimpleScalar.
I want to remove "srav/slav" (immediate arithmetic shift) from the
instruction set. I explore ss.md file but I didn't see any define_ins for
the mentioned instructions, but they are used in othe
