Hello everyone,
I am upgrading a cross compiler from 3.2 to 3.4.6
I had to change some of the TARGET description macros
in target.h file
for otherwise while building i am getting "attempt to
use poisoned" errors
Presently what is written in target.h is
1. #define CPP_PREDEFINES \
"-Dtargetname -D__targetname__ -Amachine=targetname"
corresponding macro in 3.4.6 is
"TARGET_CPU_CPP_BUILTINS"
2. #define CONST_COSTS(RTX, CODE, OUTER_CODE) \
case CONST_INT: \
return target_const_costs (RTX, OUTER_CODE);
\
case CONST: \
return 5; \
case LABEL_REF: \
return 1; \
case SYMBOL_REF: \
return ((TARGET_SMALL_MODEL)? 2: 3); \
case CONST_DOUBLE: \
return 10;
i dont know the corresponding macro in 3.4.6
3. #define ADDRESS_COST(RTX) 1
corresponding macro in 3.4.6 is "int
TARGET_ADDRESS_COST (rtx address)"
4. #define RTX_COSTS(X, CODE, OUTER_CODE) \
case MULT:
\
return COSTS_N_INSNS (2);
\
case DIV: \
case UDIV: \
case MOD: \
case UMOD: \
return COSTS_N_INSNS (30);
\
case FLOAT: \
case FIX: \
return COSTS_N_INSNS (100);
corresponding macro in 3.4.6 is "bool
TARGET_RTX_COSTS (rtx x, int code, int outer_code, int
*total)"
5. #define ASM_GLOBALIZE_LABEL(STREAM,NAME) \
do \
{ \
fputs ("\t.globl ", STREAM); \
assemble_name (STREAM, NAME); \
fputs ("\n", STREAM); \
} \
while (0)
corresponding macro in 3.4.6 is "void
TARGET_ASM_GLOBALIZE_LABEL (FILE *stream, const char
*name)"
Now to my problem :
except for TARGET_CPU_CPP_BUILTINS i dont know how
to rewrite the existing macros for 3.4.6
Can anybody help me in this regard?
Thanks in advance
Regards,
Shafi.
