[Bug target/19923] openssl is slower when compiled with gcc 4.0 than 3.3
--- Additional Comments From rakdver at atrey dot karlin dot mff dot cuni dot cz 2005-06-02 08:01 --- Subject: Re: openssl is slower when compiled with gcc 4.0 than 3.3 The assembler attributed to 4.0 was produced by mainline (or some patched version of 4.0), wasn't it? Otherwise I cannot imagine why the inner loop would be unrolled. For plain 4.0, we get the following code, which seems just fine and equivalent to the one obtained with 3.4 (one of the memory references is strength reduced, but since we still fit into registers, this is OK). I don't just now see what/whether there is some problem with the code produced by 4.1, but I also don't see anything related to addressing mode selection there. .L21: movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl(%edx), %eax movl%eax, (%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl4(%edx), %eax movl%eax, 4(%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl8(%edx), %eax movl%eax, 8(%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl12(%edx), %eax movl%eax, 12(%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl16(%edx), %eax movl%eax, 16(%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl20(%edx), %eax movl%eax, 20(%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl24(%edx), %eax movl%eax, 24(%edx) movl[EMAIL PROTECTED](%ebx,%eax,4), %eax xorl28(%edx), %eax movl%eax, 28(%edx) addl$32, %edx leal-12(%ebp), %esi cmpl%esi, %edx jne .L21 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19923

Unfortunately that moves a decl outside of its cleanup. We really should be going the other way and pushing the user of the STMT_EXPR into it. I suspect we'll need to move further along the path of making STMT_EXPRs look like real function calls, complete with an explicitly generated RESULT_DECL. -- What|Removed |Added AssignedTo|nathan at gcc dot gnu dot |unassigned at gcc dot gnu |org |dot org Status|ASSIGNED|NEW http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21440

I just removed as much as possible to avoid having too much code (from 1173 to 230 lines), but I just tried to avoid syntax errors and stuff like that, I didn't even attempt to still have something meaningful... "Input_String_Length" should actually be imported from (yet) another module: I didn't mean to leave it unitialised: would it change something? (for the record I think it's set to 250). The whole thing is definitly a bit tortured, but this can happen when some code has been growing a lot organically... Thanks!

[Bug c/21879] New: Memory management problem in new C parser
Symptoms are:
FAIL: gcc.dg/cpp/direct2.c (test for excess errors)
FAIL: gcc.dg/cpp/direct2s.c (test for excess errors)
on sparc64-solaris2.* (not visible on sparc-solaris2.* with -m64).
Parser obstack memory is wrongly reused, leading to memory corruption.
Reproducible on x86_64-suse-linux:
c-decl.c:start_function
nstack_vm = XOBNEW (&parser_obstack, struct c_label_context_vm);
nstack_vm->labels_def = NULL;
nstack_vm->labels_used = NULL;
nstack_vm->scope = 0;
nstack_vm->next = label_context_stack_vm;
label_context_stack_vm = nstack_vm;
On second stop, we have:
(gdb) p label_context_stack_vm
$9 = (struct c_label_context_vm *) 0x1375008
(gdb) p *label_context_stack_vm
$10 = {labels_def = 0x0, labels_used = 0x0, scope = 0, next = 0x1375008}
On SPARC 64-bit, the labels_used and scope fields are later corrupted in
build_function_declarator:
struct c_declarator *ret = XOBNEW (&parser_obstack, struct c_declarator);
ret->kind = cdk_function;
ret->declarator = target;
ret->u.arg_info = args;
Parser obstack memory is wrongly freed in c_parser_translation_unit, but I don't
know enough of the new C parser to debug it myself.

I don't see anything intrinsically to do with the parser in this bug; when a function finishes, label_context_stack_se and label_context_stack_vm should end up as NULL so this memory should not be live. The problem looks to me to be that if (decl1 == 0) return 0; in start_function also needs to do label_context_stack_se = label_context_stack_se->next label_context_stack_vm = label_context_stack_vm->next before returning. This problem could also apply on 4.0 branch (even if not with these testcases) so the fix should be applied there as well. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21879

[Bug c/21879] Memory management problem in new C parser
--- Additional Comments From ebotcazou at gcc dot gnu dot org 2005-06-02 17:39 --- > I don't see anything intrinsically to do with the parser in this bug; when > a function finishes, label_context_stack_se and label_context_stack_vm > should end up as NULL so this memory should not be live. Do you mean that parser_obstack is effectively a per-toplevel-decl object and that it is supposed to be dead at the end of the object's parsing, although in the present case there are objects associated with different toplevel decls allocated on it that point to each other? And I presume label_context_stack_vm is not explicitly reset to NULL on function exit because of nested functions? Maybe a few sanity checks can be added to c_parser_translation_unit so as make implicit assumptions like these more explicit. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21879

[Bug tree-optimization/17100] Missed opportunity for value range optimization
--- Additional Comments From dnovillo at gcc dot gnu dot org 2005-06-02 18:50 --- Fixed. Likely with http://gcc.gnu.org/ml/gcc-patches/2005-06/msg00127.html, but it may have been fixed earlier. The natural range for i_6 is computed as [0, 9] so this isn't something that was folded using range equivalences. -- What|Removed |Added Status|NEW |RESOLVED Resolution||FIXED Target Milestone|--- |4.1.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17100
[Bug tree-optimization/21883] New: tree-ssa-dom.c causing excessive code duplication
extern int foo1 (void), foo2 (int);
int bar (int x)
{
int varvar1, varvar2;
int z;
if (x > 913)
varvar1 = foo1 ();
else
varvar2 = foo2 (6);
#define A foo1 (); foo1 (); foo1 (); foo1 (); foo1 ();
#define B A A A A A A A A A A
#define C B B B B B B B B B B
C C C C C C C C C C C
if (x > 913)
z = varvar1 + foo1 ();
else
z = varvar2 + foo2 (6);
return z;
}
Current HEAD will duplicate all the 2500 foo1 () calls to save a if (x > 913)
comparison. With -Os almost no duplication should be allowed (only if the
duplicated instructions are expected to be shorter than the compare and branch),
and even with -O2 there should be some sensible limit.

[Bug c/21879] Memory management problem in new C parser

Yes, the parser obstack contains objects with varying lifetime but all of them should be dead at the end of a toplevel decl, so it is freed at the end of each such decl. There should never be objects associated with different toplevel decls on it, because everything that can point into it should be NULL at the end of such a decl. (Various structures that can point into it are in variables in other files, such as these lists of labels and lists of decls used inside sizeof or typeof; declarators and associated structures also live on it but should mostly only be pointed to from local variables.) Yes, nested functions mean it is not reset to NULL on function exit - and because GNU extensions allow a nested function to refer to explicitly declared labels in the containing function, it isn't clear that using the function context for this (resetting to NULL on function entry and restoring on exit; we do always have matched push_function_context / pop_function_context pairs for nested functions even with parse errors) would be right either. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21879
