Hi, I'm working on GCC 4.1.1 on spu target and get following problem:
After splitting an insn with a note REG_LIBCALL, the insn is replaced by some other insns, which don't attach REG_LIBCALL note any more, and the original one is then deleted. While the insn REG_RETVAL still points to the LIBCALL insn, which doesn't exist after the split. After reload it tries to delete the LIBCALL insn referenced by RETVAL, but it has been deleted already. The question is how to avoid deleting the LIBCALL note twice? Is it possible to have RETVAL note point to the new insn split from LIBCALL note? Any idea to solve this problem would be appreciated... Thanks! Sa
