When configured with --enable-checking=misc,tree,rtl,rtlflag,gc I'm seeing
extra RTL checking failures with 3.4.x on i686-pc-linux-gnu as seen here:
http://gcc.gnu.org/ml/gcc-testresults/2004-12/msg01282.html
The checking failures all appear to be similar:
gcc.log:gcc.dg/i386-loop-3.c:62: internal compiler error: RTL check: expected
elt 2 type 'e' or 'u', have '0' (rtx label_ref) in next_active_insn, at emit-
rtl.c:3130
gcc.log:gcc.dg/i386-unroll-1.c:17: internal compiler error: RTL check: expected
elt 2 type 'e' or 'u', have '0' (rtx label_ref) in next_active_insn, at emit-
rtl.c:3130
gcc.log:gcc.dg/unroll-1.c:16: internal compiler error: RTL check: expected elt
2 type 'e' or 'u', have '0' (rtx label_ref) in next_active_insn, at emit-
rtl.c:3130
g++.log:g++.dg/opt/longbranch2.C:62: internal compiler error: RTL check:
expected elt 2 type 'e' or 'u', have '0' (rtx label_ref) in next_active_insn,
at emit-rtl.c:3130
I don't know if these RTL failures are specific to x86 or not since it's
crashing in emit-rtl.c. I don't see these failures with 3.3.x so it's a
regression.
