[Bug go/63731] Fallback to netgo does not work
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63731 --- Comment #25 from Tatsushi Inagaki e29253 at jp dot ibm.com --- What is the most recommended way when we want to use the net package in a statically linked binary? My impression is that a statically linked binary also should call dlopen() (and thus we should export LD_LIBRARY_PATH), if the corresponding dynamically linked binary do so to resolve DNS. https://sourceware.org/glibc/wiki/FAQ#Even_statically_linked_programs_need_some_shared_libraries_which_is_not_acceptable_for_me.__What_can_I_do.3F Or, can we expect that netgo can be enabled with 'go build -a' again in Go 1.5? https://github.com/golang/go/issues/9369

Sorry, these was unintentinal commits, I will revert them soon.
FAIL: gcc.dg/noreturn-7.c (test for warnings, line 30)
Here we do merging before outputting a warning (testcase expects two warnings).
I suppose there is not much to do than -fno-ipa-cp.
Once user adds one noreturn, he will get warning for anohter, because the
functions will no longer get merged.

--- Comment #9 from Jan Hubicka hubicka at ucw dot cz ---
On Darwin we also see:
gcc.dg/attr-noinline.c (all cases fail)
Didin't Martin analyze this failure as the test case just needing /* {
dg-require-alias } */?
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65150#c13
I would just add -fno-ipa-cp. The testcase matching does not expect functions
to be turned into
wrappers - it counts number of occurences of calls after optimization. I will
fix that, too.

[Bug c/65238] New: [5 Regression] __has_attribute is not handled properly with -traditional-cpp.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65238
Bug ID: 65238
Summary: [5 Regression] __has_attribute is not handled properly
with -traditional-cpp.
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal

trivial test-case.
between r218893 and 218951 the handling of __has_attribute has regressed for
-traditional-cpp (-E)
(as an example) gcc.dg/cpp/trad/include.c has started to fail with excess
errors - if run manually:
$ ./gcc/xgcc -Bgcc /GCC/gcc-trunk/gcc/testsuite/gcc.dg/cpp/trad/include.c
-traditional-cpp -E -m32 -o include.i
In file included from /usr/include/Availability.h:145:0,

The trivial test-case compiles fine with:
$ ./gcc/xgcc -Bgcc has-attr.c -E -o t.i
and with :
$ ./gcc/xgcc -Bgcc has-attr.c -E -traditional-cpp -o t.i
has-attr.c:3:0: error: missing '(' after __has_attribute

*** set a breakpoint in malloc_error_break to debug
Of course, it seems reasonable to exclude __has_attribute from traditional-cpp
- but, in that case:
(a) the testsuite needs amendment in some places, and
(b) use of the tag should not cause the free error.

(i've only tried to build current master, which works fine now with workaround for the bug from the description)

If that's the intended behavior, then that's the same as saying type-bound procedures cannot be pure. The thread mentioned by Dominique d'Humieres seems to only apply to unlimited polymorphic, which is not part of the test case I posted.

This could be an EasyHack. About generating a patch, we would first need precise locations within format strings (PR52952), then implement the fix-it hints (PR62314) and editors like Emacs could parse them to patch the code. Unfortunately, the time I can dedicate to GCC has been very much reduced lately and I haven't been able to find anyone to continue this work.

Product: gcc

Severity: normal

Target: aarch64
This aarch64 intrinsics testcase aborts.
#include arm_neon.h
int main (int argc, char** argv)
{
int64x1_t val1;
int64x1_t val2;
int64x1_t val3;
uint64x1_t val13;

val3 = vcreate_s64(UINT64_C(0x7fff809b));
// Expect: val13 = 80001553
val13 = vcreate_u64 (UINT64_C(0x80001553));
// Expect: val14 = 0010 0002
val14 = vcombine_u64(vcgt_s64(vqrshl_s64(val1, val2),
vshr_n_s64(val3, 18)),
vshr_n_u64(val13, 11));
/* Should be . */
got = vgetq_lane_u64(val14, 0);
exp = 0;
if(exp != got)
__builtin_abort ();
}
Investigation shows that the problem is in the simplify-rtx machinery:
Combine tries to combine:
(insn 72 71 73 2 (set (reg:V2DI 117 [ D.18177 ])
(vec_concat:V2DI (reg:DI 176 [ D.18179 ])
(reg:DI 114 [ D.18168 ])))
(expr_list:REG_DEAD (reg:DI 176 [ D.18179 ])
(expr_list:REG_DEAD (reg:DI 114 [ D.18168 ])
and
(insn 104 102 105 2 (set (reg:DI 193 [ D.18168 ])
(vec_select:DI (reg:V2DI 117 [ D.18177 ])
(parallel [
(const_int 0 [0])
])))
(expr_list:REG_DEAD (reg:V2DI 117 [ D.18177 ])
(nil)))
but ends up generating:
(set (reg:DI 193 [ D.18168 ])
(reg:DI 114 [ D.18168 ]))
i.e. it picks element 1 instead of the requested element 0.
This happens during combine where it tries to to simplify a vec_select 0 of the
intermediate rtx:
(vec_concat:V2DI (const_int -1 [0x])
(reg:DI 114 [ D.18166 ]))
The relevant code in simplify-rtx has been there for some time and is broken
for all release branches. I have a patch in testing...

Sorry, the pointer should be https://gcc.gnu.org/ml/fortran/2014-12/msg00098.html The rationale refers to F08:C1278a, however in my F08 draft it is 'A local variable of a pure subprogram, or of a BLOCK construct within a pure subprogram, shall not have the SAVE attribute.'. The only related constraint I can find is C534 An assumed-size array with the INTENT (OUT) attribute shall not be polymorphic, finalizable, of a type with an allocatable ultimate component, or of a type for which default initialization is specied. but this does not apply to the test in comment 0, CCed Janus. Nevertheless replacing 'element' with 'impure elemental' allows the code to compile.

Yes, I think the test should be decoared with dg-require-alias.
hmm.. so should we understand that we used to pass that test .. incorrectly?
..
.. it's not clear to me that changing the test to require symbol alias isn't
still a regression … (I'd like to understand that the code-gen is equivalent).

[Bug c/60296] Confusing -Wformat warning on invalid format string
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60296 Manuel López-Ibáñez manu at gcc dot gnu.org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED CC||manu at gcc dot gnu.org Resolution|--- |INVALID --- Comment #2 from Manuel López-Ibáñez manu at gcc dot gnu.org --- To be honest, I find the messages by gcc far clearer (except for missing precise locations). In particular, if we think about suggesting a fix, gcc could suggest to replace %. with %.d to match '9' and then the second warning will still be valid (since there are no arguments to match %*d). Currently, gcc tries to match 9 to %. and skips both on error, that is why it complains about a missing argument for %d. GCC could not skip the argument '9' and try to match %*d with 9. I can imagine cases where one strategy is clearer than the other and viceversa. However, the clang warning does not actually say what is wrong at all. It does not seem very helpful. About your questions, yes %d refers to %*d in the format string, and the %d printed by the warning is not read from the string but hard-coded in the gcc sources. What printf does when given invalid arguments is not up to GCC but the C library that implements printf. I will close this as invalid then. Improving the location info is what will make these cases far clearer (PR52952). Then, we can print: warning: conversion lacks type at end of format [-Wformat=] printf(%.%*d\n, 9); ~^ note: use '%.d' to match argument of type 'int' printf(%.%*d\n, 9); ~^^ %.d warning: format ‘%d’ expects a matching ‘int’ argument [-Wformat=] printf(%.%*d\n, 9); ^

--- Comment #10 from Manuel López-Ibáñez manu at gcc dot gnu.org ---
(In reply to D. Hugh Redelmeier from comment #6)
If an arg is marked as a const char * (i.e. unchanging) and has the strftime
format attribute, it should be accepted as if it were a literal strftime
argument. After all, the necessary checking would have been done at this
routine's points of call.
The code that warns is this: gcc/c-family/c-format.c
if (res.number_non_literal 0)
{
/* Functions taking a va_list normally pass a non-literal format
string. These functions typically are declared with
first_arg_num == 0, so avoid warning in those cases. */
if (!(format_types[info-format_type].flags (int)
FMT_FLAG_ARG_CONVERT))
{
/* For strftime-like formats, warn for not checking the format
string; but there are no arguments to check. */
warning_at (loc, OPT_Wformat_nonliteral,
format not a string literal, format string not
checked);
}
Thus, there is nothing checking the attributes of the caller. In the same file
there is this code:
tree c;
for (c = TYPE_ATTRIBUTES (TREE_TYPE (current_function_decl));
c;
c = TREE_CHAIN (c))
if (is_attribute_p (format, TREE_PURPOSE (c))
(decode_format_type (IDENTIFIER_POINTER
(TREE_VALUE (TREE_VALUE (c
== info.format_type))
break;
if (c == NULL_TREE)
{
/* Check if the current function has a parameter to which
the format attribute could be attached; if not, it
can't be a candidate for a format attribute, despite
the vprintf-like or vscanf-like call. */
tree args;
for (args = DECL_ARGUMENTS (current_function_decl);
args != 0;
args = DECL_CHAIN (args))
{
if (TREE_CODE (TREE_TYPE (args)) == POINTER_TYPE
(TYPE_MAIN_VARIANT (TREE_TYPE (TREE_TYPE
(args)))
== char_type_node))
break;
}
if (args != 0)
warning (OPT_Wsuggest_attribute_format, function might
be possible candidate for %qs format
attribute,
format_types[info.format_type].name);
}
I'm confident that the above code can be adjusted and moved to the point of the
warning in order to check that the caller of strftime has an attribute format
of type 'strftime' that refers to the same declaration as the nonliteral format
argument in the call to strftime, then avoid warning. I'm not planning to work
on this though.

On Darwin we also see:
gcc.dg/attr-noinline.c (all cases fail)
Didin't Martin analyze this failure as the test case just needing /* {
dg-require-alias } */?

That was before Honza did his last round of analysis/changes, just want to be
sure what the correct fix is - after all we used to pass that test, right?

One bug with thunks I am aware of is demonstrated by the following testcase:
struct A {
A() {ptr=b;}
A(const A a) {ptr = b;}
void test() { if (ptr != b) __builtin_abort ();}
int b;
int *ptr;
};
A test1(A a)
{
a.test();
return a;
}
A test2(A a)
{
a.test();
return a;
}
__attribute__ ((noinline))
void
test_me (A (*t)(A))
{
struct A a, b=t(a);
b.test ();
}
int
main()
{
test_me (test1);
test_me (test2);
return 0;
}
we turn test2 into a thunk but after inlining the thunk we end up with
producing extrra copy of return value A.

I'd like to propose that the value of an empty object be printed as { }
regardless of its type. I.e., a std::bitset0 as std::bitset { }, a
std::tuple as std::tuple { }, and an empty std::vectorT as
std::vectorT of length 0, capacity N = { }
Yes, I like this suggestion.

CC||vogt at linux dot vnet.ibm.com
--- Comment #4 from Dominik Vogt vogt at linux dot vnet.ibm.com ---
This also happens intermittently on my s390x development machine (a zEC12) with
the current 5.0 development trunk.
(In reply to Ian Lance Taylor from comment #1)
Interestingly, the time for cmpldivide.go on SPARC appears to be primarily
in the register allocator while compiling.
To be specific:
LRA hard reg assignment : 217.88 (95%) usr 0.29 (74%) sys 218.24 (95%)
wall 0 kB ( 0%) ggc
This is true even though no -O option is used.
Actually, on s390x it does not happen
--
Observation
---
Compile time of the test is normally about 4 minutes, but I've seen ~3:50 as
well as ~4:45. When the machine is slow for some reason (probably does not
matter why), compile time may become more than 5 minutes and therefore the test
times out.
Explanation
---
The test defines a long array of structures with three complex numbers in
cmplxdivide1.go:
var tests = []Test{
Test{complex(0, 0), complex(0, 0), complex(-nan, -nan)},
Test{complex(0, 0), complex(0, 1), complex(0, 0)},
...
}
The constants like nan map to exported symbols of the math package (unlike C
where this would probably be done with macros): nan appears in the code as
math.NaN@plt. With dynamic linkage the actual value is unknown at compile
time, and the structure tests is initialised in the init function of the main
package. Compiling with -O0, the executable is about 1.5 MB, and more than 90%
of that is code in the init function. For each line in the table the assembler
instuctions to initialise is consume about 420 bytes.
As far as I was told, the register allocation code has some trouble with huge
basic blocks of simple code like in this case, when the number of possibilities
explodes.
Note: With -O3, the code compiles in less than two seconds, probably because
the code in the init function is reduced drastically before the expensive
register allocation pass.
