[Bug middle-end/19752] New: error: unrecognizable insn

[jorgen dot moth at uni-c dot dk]

When installing TeX-live 2004 on a HP-box (hpux11.11) with gcc –version:

gcc -v
Reading specs from /usr/unic/libexec/gcc/3.4.2/lib/gcc/hppa1.1-hp-
hpux11.11/3.4.2/specs
Configured with: ../gcc-3.4.2/configure --prefix=/usr/unic/share/gcc/3.4.2 --

as=/usr/local/bin/as
Thread model: single
gcc version 3.4.2

the following excerpt of the dvidvi.c program

integer myatol(s)
char **s ;
{
   register char *p ;
   register integer result ;

   result = 0 ;
   p = *s ;
   while ('0' <= *p && *p <= '9') {
      if (result > 100000000)
         error("! arithmetic overflow in parameter") ;
      result = 10 * result + *p++ - '0' ;
   }
   if (p == *s)
      usage() ;
   else {
      *s = p ;
      return(result) ;
   }
}

Resulted in an internal compiler error. The compiler call was:

gcc -DNO_DEBUG -I. -I. -I.. -I./.. -DUNIX  -DNeedFunctionPrototypes -
DHAVE_CONFIG_H -I../kpathsea -I./../kpathsea  -g -O2  -c dvidvi.c -o dvidvi.o
