I agree, but unfortunately the compiler does not...

With that lra.c change, I get extra fails:

+FAIL: gcc.target/i386/20011029-2.c (internal compiler error)
+FAIL: gcc.target/i386/20011029-2.c (test for excess errors)
+FAIL: gcc.target/i386/pr21291.c (internal compiler error)
+FAIL: gcc.target/i386/pr21291.c (test for excess errors)

These are constrain_operands(1) failures in check_rtl. Apparently some
relevant info is lost in lra_update_insn_recog_data. Not sure how to
debug this...

Ciao!
