1999 when optimizing this file with target i960-vxworks. I haven't

2001 in the second call to SKIP_PROLOGUE below, the compiler somehow
2002 does not realize that the statement val = find_pc_line (...) will
2003 change the values of the fields of val. It extracts the elements
2004 into registers at the top of the block, and does not update the
2005 registers after the call to find_pc_line. You can check this by
2006 inserting a printf at the end of find_pc_line to show what values
2007 it is returning for val.pc and val.end and another printf after
2008 the call to see what values the function actually got (remember,
2009 this is compiling with cc -O, with this patch removed). You can
2010 also examine the assembly listing: search for the second call to
2011 skip_prologue; the LDO statement before the next call to
2012 find_pc_line loads the address of the structure which
2013 find_pc_line will return; if there is a LDW just before the LDO,
2014 which fetches an element of the structure, then the compiler
2017 Setting val to volatile avoids the problem. We must undef
2018 volatile, because the HPPA native compiler does not define
2019 __STDC__, although it does understand volatile, and so volatile
