Hello, The problem in this PR is that new basic blocks can be created if the scheduler moves speculative insns and adds recovery code, but the bb_state* arrays are allocated only at the start of scheduling a region and are not set up to deal with changing last_basic_block.
Fixed by resizing the arrays if necessary. This fixes most of the
testsuite failures on ia64:
=== gcc Summary ===
-# of expected passes 81541
-# of unexpected failures 505
+# of expected passes 81839
+# of unexpected failures 64
# of unexpected successes 18
# of expected failures 341
-# of unresolved testcases 66
-# of unsupported tests 1198
+# of unresolved testcases 7
+# of unsupported tests 1208
Bootstrapped&tested on ia64-unknown-linux-gnu. OK for trunk?
Ciao!
