Hey Thanks for the reply..
The compiler version is 2.95. I have added the dump
file name ".greg2" after the "jump2" optimization and
".stack" optimization in the toplev.c file which is
shown below.
if (greg2_dump)
open_dump_file(".greg2", decl_printable_name
(decl,2));
r1_greg2(config_info);
dump_rtl(".greg2", decl, print_rtl_with_bb, insns);
Also how can i update the lifeness of the register
???. I think thts the problem..the function call
r1_greg2(config_info);
calls my file "greg2mod.c" in which iam retrieving the
head [first instruction] of the basic block 2 and then
inserting the two instructions which i have mentioned
earlier using the macros at the end.. after the pass ,
these are the codes that gets executed
/* Now turn the rtl into assembler code. */
TIMEVAR (final_time,
{ rtx x; char *fnname;
/* Get the function's name, as described by its RTL.
This may be different from the DECL_NAME name used in
the source file. */
x = DECL_RTL (decl); br> if (GET_CODE (x) != MEM)
abort ();
x = XEXP (x, 0);
if (GET_CODE (x) != SYMBOL_REF)
abort ();
fnname = XSTR (x, 0);
//This is where the call to the final.c file is done
assemble_start_function (decl, fnname);
final_start_function (insns, asm_out_file, optimize);
final (insns, asm_out_file, optimize, 0);
final_end_function (insns, asm_out_file, optimize);
assemble_end_function (decl, fnname);
if (! quiet_flag)
fflush (asm_out_file);
......
So how can i make the registers live??? pls help me
kripa
