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. - - Setting val to volatile avoids the problem. We must undef - volatile, because the HPPA native compiler does not define - __STDC__, although it does understand volatile, and so volatile - will have been defined away in defs.h. */ -#undef volatile - volatile struct symtab_and_line val; -#define volatile /*nothing */ -#else struct symtab_and_line val; -#endif register char *p, *p1; char *q, *pp, *ii, *p2; #if 0 |
