[Bug middle-end/91146] -Werror=array-bounds if compile with -fsanitize=address
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91146
--- Comment #2 from Grigorii Lipenko ---
I remove gtest.h.
#include "small_vector.h"
class A
{
public:
virtual void f () = 0;
};
class B : public A
{
public:
void f () override
{
small_vector v;
v.insert (v.begin (), 1);
}
};
int main ()
{
B b;
(void)b;
return 0;
}
I get the warning in this case.
If comment inheritance then the warning disappears.

--- Comment #3 from Jonathan Wakely ---
Another useful tunable would be to alter the meaning of the "default" token for
the std::random_device constructor:
if (token == "default")
{
default_token = true;
fname = "/dev/urandom";
#if defined _GLIBCXX_USE_CRT_RAND_S
which = rand_s;
#elif defined USE_RDSEED
which = rdseed;
#elif defined USE_RDRAND
which = rdrand;
#elif defined _GLIBCXX_USE_DEV_RANDOM
which = device_file;
#else
# error "either define USE_MT19937 above or set the default device here"
#endif
}
In a build of libstdc++ that defaults to rdrand it would be useful to be able
to force "default" to mean /dev/urandom or /dev/random at runtime, to
workaround RDRAND bugs in AMD processors.

Although SLP still generates SIMD code, it looks much better than previous code
with memory load/store. Performance is expected to be better as no redundant
load/store.

I know the "real" code this testcase is from has actual operations
in place of the b[N] reads, for the above vectorization looks somewhat
pointless given we end up decomposing the result again.
So the appropriate fix would of course be to vectorize the reduction
loop (but that hits the sign-changing reduction issue).

[Bug target/91148] PowerPC build gets several warnings due to -Wformat-diag
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91148
--- Comment #3 from Segher Boessenkool ---
12593 |"internal error: builtin function %qs already processed",
That's a fatal_error; users will never see that, *no one* will ever see that.
14747 | error ("builtin function %qs is only valid for the cell processor",
name);
The functions are called __builtin_* already; if anything, we should delete the
"builtin function" part of the error message.
[a lot more like this...]
17392 |"internal error: builtin function %qs had an unexpected "
17393 |"return type %qs", name, GET_MODE_NAME (h.mode[0]));
internal error. s/builtin function //
rs6000.c:26987:12: warning: misspelled term 'floating point' in format; use
'floating-point' instead [-Wformat-diag]
26987 | error ("use of decimal floating point types in AltiVec types is
invalid");
Is "decimal floating-point" the best style tip we can give here? Heh.
Anyway, can we have a -Wno-noise option if we have to have these warnings?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91148 --- Comment #4 from Segher Boessenkool --- And I am quite serious about that last point: I have to redirect stderr to file and search that with a text editor to find the errors, there are a dozen screenfuls of useless warnings (about two screens per warning) hiding the real problems. And no, not most in rs6000 at all.

Bug ID: 91150
Summary: [10 Regression] wrong code with -O -mavx512vbmi due to
wrong writemask
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: zsojka at seznam dot cz
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu
Created attachment 46594
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46594&action=edit
reduced testcase
Output:
$ x86_64-pc-linux-gnu-gcc -O -mavx512vbmi testcase.c
$ sde64 -- ./a.out
Aborted
At the assembly level, the problem seems to be:
# testcase.c:12: {
vpxor xmm2, xmm2, xmm2# tmp117
mov eax, 4294967295 # tmp119,
vmovdqa64 zmm4, ZMMWORD PTR [rsp+8] # tmp118, b

# testcase.c:11: a <<= (v64u64) (v64u128)
vpsllvq zmm1, zmm1, zmm4# a, tmp123, tmp118
vmovdqu8 is using the k1 mask to load zeros to given bytes - the mask should be
0x instead (only the lowest-order 16byte word is kept)

Bug ID: 91155
Summary: __PRETTY_FUNCTION__ gets truncated when char template
parameter is '\0'
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: d.frey at gmx dot de
Target Milestone: ---
This is a regression against 8.x:

template< typename T > void test()
{
std::cout << __PRETTY_FUNCTION__ << std::endl;
}
int main()
{

}
Incorrect output with GCC 9.1:
void test() [with T = dummy<'
Correct output with GCC 8.3:
void test() [with T = dummy<'\000'>]

[Bug target/89096] [7/8/9/10 regression] AIX 7 linker rejects _.ro_ sections by default
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89096 --- Comment #14 from Andrew Paprocki --- I can reproduce this error with a much simpler project, pcre, that uses autotools and libtool. Using pcre 8.42 from https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz $ mkdir build $ cd build $ CC=gcc-6 CXX=g++-6 OBJECT_MODE=32 CFLAGS="-maix32 -O" CXXFLAGS="-maix32 -O" ../configure --enable-unicode-properties --enable-pcre16 --enable-pcre32 --enable-jit $ OBJECT_MODE=32 make V=1 ... g++-6 -DHAVE_CONFIG_H -I. -I.. -maix32 -O -MT pcrecpp_unittest-pcrecpp_unittest.o -MD -MP -MF .deps/pcrecpp_unittest-pcrecpp_unittest.Tpo -c -o pcrecpp_unittest-pcrecpp_unittest.o `test -f 'pcrecpp_unittest.cc' || echo '../'`pcrecpp_unittest.cc mv -f .deps/pcrecpp_unittest-pcrecpp_unittest.Tpo .deps/pcrecpp_unittest-pcrecpp_unittest.Po /bin/sh ./libtool --tag=CXX --mode=link g++-6 -maix32 -O -o pcrecpp_unittest pcrecpp_unittest-pcrecpp_unittest.o libpcrecpp.la -lpthreads libtool: link: g++-6 -maix32 -O -o .libs/pcrecpp_unittest pcrecpp_unittest-pcrecpp_unittest.o -L/tmp/pcre/build/.libs -L./.libs -lpcrecpp -lpcre -L/path/to/gcc/lib -lstdc++ -lm -lpthreads -Wl,-blibpath:/usr/local/lib:/path/to/gcc/lib:/path/to/gcc/lib/.:/usr/lib:/lib ld: 0711-308 SEVERE ERROR: Object pcrecpp_unittest-pcrecpp_unittest.o, csect <_pcrecppunittest.ro_> The csect is part of the .text section. collect2: error: ld returned 12 exit status Makefile:1518: recipe for target 'pcrecpp_unittest' failed make[1]: *** [pcrecpp_unittest] Error 1 I've narrowed this down to the usage of the -bsvr4 linker flag, which we use because we depend on passing multiple -R parameters and the linker behavior described in the man page: -R Path ... Multiple instances of this option are concatenated together with each Path separated by a colon. If -bsvr4 is placed on the collect2 command line (obtained from -v output of the link), the link fails with the output above. I know in the past flag ordering has mattered, and in this case it fails in the same manner when it is both the first flag and last flag on the command line. This fails without any usage of -bexpall and -brtl.

[Bug libstdc++/91156] New: The associated laguerre polynomial should allow nedative arguments.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91156 Bug ID: 91156 Summary: The associated laguerre polynomial should allow nedative arguments. Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: emsr at gcc dot gnu.org Target Milestone: --- The associated Laguerre polynomial should allow negative arguments. It's not often used for negative arguments but it's a polynomial and it doesn't do anything nasty for negative arguments. Unlike the case for associated Lagendre polynomial the origin is not a branch point.
