With today's 3.4.x CVS, when configured with --enable-
checking=misc,tree,rtl,rtlflag,gc --enable-languages=c,objc,c++,f77,java --
enable-multilib=no I get an RTL checking failure on x86_64-unknown-linux-gnu in
gcc.dg/titype-1.c:
gcc.dg/titype-1.c:21: internal compiler error: RTL check: expected elt 0
type 'E' or 'V', have 'i' (rtx reg) in ix86_va_arg, at config/i386/i386.c:3331
To reproduce, run this command:
cc1 -fpreprocessed titype-1.i -quiet -dumpbase titype-1.c -mtune=k8 -ansi -
auxbase titype-1 -pedantic-errors -ansi -version -o titype-1.s
