https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64498 --- Comment #2 from Jan Hubicka hubicka at ucw dot cz --- Problem is hidden in flag_var_tracking_assignments, which is set to false. Thus, MAY_HAVE_DEBUG_INSNS is set to false. Unfortunately, Firefox contains couple of third party libraries that have -g as a default option. So that DCE after a statements removal does not remove debug statements that use result of a statement and verifier fails. flag_var_tracking_assignments is marked as Optimization in common.opt while rest of debug machinery is not Optimization. This means that we try to preserve assignments in functions that was compiled with -g at compile time, but then we never consume it Shall we drop flag_var_tracking_assignments to 0 and remove the debug statements after streaming in in these cases? Also inliner probably needs to remove the statements when it inlines from function with flag_var_tracking_assignments to one with !flag_var_tracking_assignments Honza

I could add, though, that the compiler should have said something. Also, why did it compile just fine with -O0? Sounds like a bug (we should error immediately here IMHO). Probably needs to annotate the CIF codes with whether this is fatal (won't change with other inlining, IPA or LTO). OTOH the headers are also poorly designed to trigger this kind of error. Maybe we want to support __attribute__((always_inline(ISA not enabled))) instead to be able to print a custom error message?

[Bug lto/64374] [5.0 regression] LTO ICE in extract_insn, at recog.c:2327
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64374 --- Comment #6 from Jakub Jelinek jakub at gcc dot gnu.org --- It can't have the same resolution though, that PR was resolved by not streaming the target nodes at all for offloading. In this case there is no offloading. If flag_pic is recorded somewhere in target node (where, x86_isa_flags, somewhere else?), then supposedly during LTO reading that should be updated from global flag_pic. I think it doesn't make sense to have flag_pic only in some routines and not in others, so flag_pic should be treated as a global flag.

[Bug tree-optimization/64567] New: missed optimization: redundant test before clearing bit(s)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64567
Bug ID: 64567
Summary: missed optimization: redundant test before clearing
bit(s)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rv at rasmusvillemoes dot dk
(Not sure the Component is correct). gcc fails to optimize
if (foo FLAG)
foo = ~FLAG;
into simply unconditionally doing foo = ~FLAG. Currently, the above code
sequence generates four instructions (mov, and, test, cmov) whereas a single
and would be sufficient. Note that this is a valid transformation regardless of
how many bits are set in FLAG; it doesn't even have to be a compile-time
constant (but must of course be side-effect free).
gcc also doesn't optimize the dual
if (!(foo FLAG))
foo |= FLAG;
into foo |= FLAG;. That transformation is however only valid when FLAG is known
to consist of only a single bit (so would probably require either a
compile-time constant where this can be checked or an expression of the form 1
something).
Trivial test case below. I'd expect foo and foo2 to compile to the same code,
and similarly for baz and baz2.
$ cat test.c
#define F1 0x04
#define F2 0x08
int bar(unsigned flags);
int foo(unsigned flags)
{
if (flags (F1 | F2))
flags = ~(F1 | F2);
return bar(flags);
}
int foo2(unsigned flags)
{
flags = ~(F1 | F2);
return bar(flags);
}
int baz(unsigned flags)
{
if (!(flags F1))
flags |= F1;
return bar(flags);
}
int baz2(unsigned flags)
{
flags |= F1;
return bar(flags);
}

The bug is that convert_memory_address (Pmode, ...) is called twice, which is not possible for VOIDmode constants. As optabs.c (indirectly from emit_indirect_jump) already calls it, because the argument is built with create_address_operand and the EXPAND_ADDRESS case in maybe_legitimize_operand calls convert_memory_address (Pmode, ...), the other convert_memory_address call is only harmful. I don't have easy access to any POINTERS_EXTEND_UNSIGNED target though, so can't test it easily.

TER gobbles up the whole function though and maybe debug expression expansion is slightly different (also due to operand canonicalization). I note that we don't fold x % x (to preserve the x == 0 exception), a missed optimization opportunity is to do if (x == 0) __builtin_trap (); at the very first point we encounter that (possibly during VRP if VRP detects that it can simplify further expressions with x != 0 knowledge). Note that this bug may be an effective dup of another one.

[Bug libstdc++/64535] Emergency buffer for exception allocation too small
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64535
--- Comment #11 from Richard Biener rguenth at gcc dot gnu.org ---
(In reply to Richard Biener from comment #4)
Is the following required to work?
#include exception
#include new
#include sys/resource.h
struct large
{
char s[1024*1024*1024];
};
int main()
{
rlimit lim;
lim.rlim_cur = 1024*1024*1024;
lim.rlim_max = 1024*1024*1024;
setrlimit (RLIMIT_AS, lim);
try {
throw large ();
} catch (large) {
} catch (std::bad_alloc) {
}
}
I get
./a.out
terminate called without an active exception
Aborted
If reading 15.1.4 (Exception Handling / Throwing an exception) correctly
then allocation happens in an unspecified way but according to 3.7.3.1
which specifies that if the allocation function that fails to allocate
storage shall throw std::bad_alloc (if not marked with throw ()). But
it isn't specified if the unspecified EH allocation function is
marked with throw ().
In particular 15.5.1 (The std::terminate function) doesn't list OOM
in allocating an exception as cause of abandoning exception handling.
It would be nice to get clarification from the standards body on what
shall happen if EH allocation runs into OOM situations.

[Bug middle-end/64554] using _mm_clmulepi64_si128 doesn't error with -O0
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64554 --- Comment #7 from Jakub Jelinek jakub at gcc dot gnu.org --- (In reply to Richard Biener from comment #6) (In reply to charles from comment #5) No you're right. I could add, though, that the compiler should have said something. Also, why did it compile just fine with -O0? Sounds like a bug (we should error immediately here IMHO). Probably needs to annotate the CIF codes with whether this is fatal (won't change with other inlining, IPA or LTO). OTOH the headers are also poorly designed to trigger this kind of error. Maybe we want to support __attribute__((always_inline(ISA not enabled))) instead to be able to print a custom error message? The difference is that for __OPTIMIZE__ _mm_clmulepi64_si128 is implemented as always_inline function (surrounded by #pragma GCC target(pclmul)), so for -O1+ the inlining error is expected, such function can't be inlined into the current function, and always_inline mandates that it is inlined (without always_inline it would simply not be inlined, and the out of line _mm_clmulepi64_si128 would use the pclmul ISA, while the caller would not). For -O0, this is implemented using a macro, since the last argument must be a constant, and the reason you get no error is that the function is const and you don't use the result, so it is DCEd. If you actually use the result (at -O0 it is enough to store it into say __m128i c = _mm_clmulepi64_si128(a, b, 1); , for -O1 you'd need something better, store into volatile var, or global var or otherwise make sure it isn't DCEd), then you get this diagnosed: /tmp/z.c: In function ‘main’: /tmp/z.c:6:11: error: ‘__builtin_ia32_pclmulqdq128’ needs isa option -m32 -mpclmul __m128i c = _mm_clmulepi64_si128(a, b, 1); ^ So I don't see any bug on the gcc side here.

I welcome libstdc++ coding style issues pointed out and general comments on whether this approach is fine (also unifying the dependent allocations in here). TODO: implement free-list sorting and merging of free-list entries Sofar tested by forcing the use of the emergency allocator (as in the patch, see #if 1) by bootstrapping and testing C++ (hopefully sorted out a last issue, test re-running).

Maybe, it's not 100% clear to me as the small remains could be merged with a released entry to an even larger one. That said, I tried to make the allocation class generic enough for re-use, but adding a min_free_size const is certainly possible (template parameters for arena size and minimum free list element size). If re-testing finishes successfully I'll give the sorting and merging a stab, shouldn't be too difficult.

--- Comment #2 from Pawel Sikora pluto at agmk dot net ---
(In reply to Manuel López-Ibáñez from comment #1)
A minimized testcase would be helpful. Using delta would probably remove
already a lot: https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction
one more small testcase w/o stl with missed warning.
struct Y
{
~Y(); // comment this line to get proper warning about 'unused y variable'
};
struct X
{
static Y get();
};
int main()
{
Y y = X::get();
}
clang 3.5.0 warns in both (w/ and w/o Y dtor) variants.

[Bug target/64460] ARM ICE on valid code
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64460 --- Comment #6 from Joel Sherrill joel at gcc dot gnu.org --- (In reply to ktkachov from comment #5) (In reply to Joel Sherrill from comment #4) (In reply to ktkachov from comment #3) I have a fix in the works. The bug is down to the shift attribute value in one of the patterns, although only xscale_sched_adjust_cost uses that attribute. Awesome! I was about to start another attempt at a git bisect but it sounds like you don't need it. Let me know if it is worth running. Thanks, but no need. I think I've got the root cause and I got a fix that fixes the testcase, I just need to put it through testing. A testsuite-appropriate reduced testcase would be nice I guess, although I'll kick off a reducer soon. FWIW the head now builds for arm-rtems again but the bug is still present with 15b6c83e88101ec7e2efedc114a7940cfbffa479. FWIW there are a few warnings building the ARM: ../../../../../../gcc/libgcc/config/arm/fp16.c:97:1: warning: no previous prototype for '__gnu_h2f_internal' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:122:1: warning: no previous prototype for '__gnu_f2h_ieee' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:128:1: warning: no previous prototype for '__gnu_h2f_ieee' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:134:1: warning: no previous prototype for '__gnu_f2h_alternative' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:140:1: warning: no previous prototype for '__gnu_h2f_alternative' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/unwind-arm-common.inc:245:29: warning: cast discards 'const' qualifier from pointer target type [-Wcast-qual] ../../../../../../gcc/libgcc/emutls.c:159:13: warning: implicit declaration of function 'calloc' [-Wimplicit-function-declaration] ../../../../../../gcc/libgcc/emutls.c:159:13: warning: incompatible implicit declaration of built-in function 'calloc' ../../../../../../gcc/libgcc/emutls.c:171:13: warning: implicit declaration of function 'realloc' [-Wimplicit-function-declaration] ../../../../../../gcc/libgcc/emutls.c:171:13: warning: incompatible implicit declaration of built-in function 'realloc'
[Bug jit/63854] Fix memory leaks seen in JIT
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63854
--- Comment #30 from David Malcolm dmalcolm at gcc dot gnu.org ---
(In reply to David Binderman from comment #29)
Similar thing in the same area, caught using static analyser cppcheck:
[gcc/jit/jit-playback.c:1791]: (error) Resource leak: f_in
Source code is
if (!feof (f_in))
{
add_error (NULL, error reading from %s, path);
free (result);
return NULL;
}
fclose (f_in);
It looks to me like a call to fclose needs to happen just before
the return.
Thanks. I've fixed this in r219487.

[Bug libstdc++/64571] [5.0 Regression] Link failure with fstream due to new string implementation
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64571 --- Comment #1 from Jonathan Wakely redi at gcc dot gnu.org --- They are defined in src/c++11/fstream-inst.cc so I think I just need to add the new symbols to the linker script. I'm surprised the testsuite didn't catch it though!
