Since our org is still making use of gcc 4.1.2 - hence the concern.
Please let me know on usgae of MELT.
Thanks but checking for cfun is NULL also does not helps me out I get
the same issue:
/* traverse each basic block and print all statements */
FOR_EACH_BB (bb){ /* in any order */
if(cfun == NULL)
return;
bbcounter++;
printf("\n-> entering bb # %d (internal #: %d)\n", bbcounter, bb->index);
stmtcounter=0;
for(si = bsi_start(bb); !bsi_end_p(si); bsi_next(&si)){
stmtcounter++;
printf(" encountering statement #%2d: ", stmtcounter);
stmt = bsi_stmt(si);
print_generic_stmt (stderr, stmt, 0);
}
}
