Bug ID: 97578
Summary: ice during IPA pass: inline
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C code:
typedef long unsigned int size_t;
typedef unsigned char __uint8_t;
typedef unsigned int __uint32_t;
typedef __uint8_t uint8_t;
typedef __uint32_t uint32_t;
struct md5_s {
uint32_t nblocks;
uint8_t buf[64];
int count;
};
typedef struct md5_s MD5_CONTEXT;
void * md5_write_context;
static void md5_write( const void *inbuf_arg , size_t inlen) {
const unsigned char *inbuf = inbuf_arg;
MD5_CONTEXT *hd = md5_write_context;
if( hd->count == 64 ) transform( hd, hd->buf );
hd->nblocks++;
if( !inbuf ) return;
if( hd->count ) md5_write( 0, 0 );
while( inlen >= 64 ) ;
for( ;
inlen && hd->count < 64;
inlen-- ) hd->buf[hd->count++] = *inbuf++;
}
void * md5_final_context;
static void md5_final( void) {
md5_write( 0, 0);
}
void AddMD5( const void *data, size_t len ) {
md5_write( data, len );
}
void EndMD5( struct md5_s *h ) {
md5_final( );
}
compiled with recent gcc trunk and flag -g -O3, does this:
during IPA pass: inline
bug659.c: In function ‘AddMD5’:
bug659.c:30:9: internal compiler error: Segmentation fault
30 | md5_write( data, len );

Here is a second simpler test case:
int a;
static void b(int c) {
if (a)
while (c)
b(0);
d();
}
void e(c) { b(c); }
void f() { e(0); }

--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
What hits us here is the hack I needed to introduce to
ipa_param_adjustments::modify_call which triggers materialization to make debug
info code working. In this case redirection happens from tree-inline and
materialization gets us back to tree-inline. Inliner is however not intended to
be recursive (it uses bb->aux pointers and in this case it will use it twice).
Martin, Jambor,
it would be really great if we did not need to materialize. I do not see how
attaching debug info to decls can work if caller is in one partition and callee
in another.
We could also just add a loop walking all such calls and trigger
materialization before going to tree-inline to avoid the recursion problem, but
still IMO debug info will get missing on the partitioning boundary. We could
also just avoid the (ab)use of bb->aux and replace it by a vector here which
would be also an option.

Hi,
this patch fixes the ICE, though I think we do have a design issue here
while producing debug info across ltrans boundary.
Martin, Jakub: as discussed on IRC it would be nice to add predicate
when the body is really needed and avoid materializing if it is not.
Can you add one?
Something like param_adjustemnts->need_callee_parm_decls_p ()

I think that in practice the existence of param_adjustemnts is by far
the biggest part of the test and the patch already checks for that.
A more precise check would probably be the following?
/* Return true if any of the original parameters of the function has been
removed or replaced. */
bool
ipa_param_adjustments::orig_parameter_removed_p ()
{
if (m_always_copy_start == 0)
return false;
unsigned adj_len = vec_safe_length (m_adj_params);
if (adj_len < m_always_copy_start)
return true;
unsigned i;
for (i = 0; i < m_always_copy_start; i++)
{
ipa_adjusted_param *apm = &(*m_adj_params)[i];
if (apm->op != IPA_PARAM_OP_COPY
|| apm->base_index != i)
break;
}
if (i == m_always_copy_start)
return false;
/* In all likelihood, the ith parameter has been removed, verify. */
bool complex_case = false;
for (unsigned j = i; j < adj_len; j++)
{
ipa_adjusted_param *apm = &(*m_adj_params)[j];
if (apm->op == IPA_PARAM_OP_COPY
|| apm->base_index == i)
{
complex_case = true;
break;
}
}
if (!complex_case)
return true;
auto_vec<bool, 16> kept;
kept.safe_grow_cleared (m_always_copy_start - i, true);
for (unsigned j = i; j < adj_len; j++)
{
ipa_adjusted_param *apm = &(*m_adj_params)[j];
if (apm->op == IPA_PARAM_OP_COPY)
kept[apm->base_index - i] = true;

OK, I comitted patch as is and we could see if any memory can be conserved by
being more precise. I still think the debug info should not need decls here.

It needs to refer to the DW_TAG_formal_parameter DIEs, and only the PARM_DECLs

It has problem with the partitioning (if we call a callee from different
parititon) and also if the callee is compiled before caller (as it
should) we will call cgraph_node::release_body and that will likely
remove pointer to them.

It has problem with the partitioning (if we call a callee from different
parititon) and also if the callee is compiled before caller (as it
should) we will call cgraph_node::release_body and that will likely
remove pointer to them.

--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I've put the [11 Regression] marker back in the summary, since it looks to have
been removed accidentally. But maybe it's fixed since comment 7, so not a
regression now? In which case, it shouldn't be P1, and a comment saying why
it's still open would help.

--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Resetting to P3, as the state is unknown.
It really can't be a P1, at least not for 11.3, if it has been introduced in
r11-4267, i.e. before 11.1 release, because if it is still not fixed, 11.1 and
11.2 would have the same bug.

I tried out the code in the original bug, and it looks fine to me.

--- Comment #16 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I tend to think Honza kept the bug open as a reminder to look into things
listed in comment #8. Those should probably be tracked in another bug,
alternatively this one should be adjusted to reflect that.
