[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 --
exec-prefix=/usr/unic/libexec/gcc/3.4.2 --with-gnu-as --with-
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 > 1)
 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

…

To avoid the compiler error it helps to move the last "return(result" outside 
the curly brackets of the last else statement (literally removing the pair of 
curly brackets of the else statement). This change of code introduces no 
semantic change as "usage()" actually error-exits after printing some how-to 
information for using dvidvi.
