symtab.c (decode_line_1): avoid a bug in the HP9000/700 native
compiler; see the comment in the file.
Here's the comment from the file:
/* FIXME: The native HP 9000/700 compiler has a bug which appears
when optimizing this file with target i960-vxworks. I haven't
been able to construct a simple test case. The problem is that
in the second call to SKIP_PROLOGUE below, the compiler somehow
does not realize that the statement val = find_pc_line (...) will
change the values of the fields of val. It extracts the elements
into registers at the top of the block, and does not update the
registers after the call to find_pc_line. You can check this by
inserting a printf at the end of find_pc_line to show what values
it is returning for val.pc and val.end and another printf after
the call to see what values the function actually got (remember,
this is compiling with cc -O, with this patch removed). You can
also examine the assembly listing: search for the second call to
skip_prologue; the LDO statement before the next call to
find_pc_line loads the address of the structure which
find_pc_line will return; if there is a LDW just before the LDO,
which fetches an element of the structure, then the compiler
still has the bug. */
