I can't reproduce it on i386-pc-linux, and this warning is clearly a deficiency in control flow analysis, something that isn't supposed to vary on a per-host basis. > The argpointer > elimination problem still remains - crosscompiler does it correctly, > bootstrapped compiler doesnt. There definitely must be yet another bug besides the one found by Andreas. I'm still running make bootstrap on my m68k-netbsd account, so I can't confirm your findings :-( > The infinite recrusion with when compiling cp-demangle also remains. Have you tried with a newer GCC snapshot? -- // Bernardo Innocenti - Develer S.r.l., R&D dept. \X/ http://www.develer.com/
