Wait, isn`t XPASS an unexpected (i.e. erroneous) pass?
I know that XFAIL = expected fail, so I don`t consider it a fail. But what

Bug ID: 83538
   Summary: std::match_results C++14 conformance issue: reference

   Product: gcc
   Version: 8.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: libstdc++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: andrey.y.guskov at intel dot com
  Target Milestone: ---

C++14 standard (page 1123, see here:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf#1137) says:

namespace std {
template >>
class match_results {
public:
typedef sub_match value_type;
typedef const value_type& const_reference;
typedef value_type& reference;
...

As of now, std::match_results implementation disagrees with the standard in
that it does not consider 'reference' equal to 'value_type&'.
I made a reproducer to prove that:

#include 
template  struct diff { static const bool s = true; };
template  struct diff { static const bool s = false; };
typedef std::match_results > >
m;
int main() { return !printf((diff::s)? "FAIL\n" :
"PASS\n"); }

C++14 standard (page 1114, see here:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf#1128) says:

explicit basic_regex(const charT* p, flag_type f =
regex_constants::ECMAScript);
Requires: p shall not be a null pointer.
Throws: regex_error if p is not a valid regular expression.
Effects: Constructs an object of class basic_regex; the object’s internal
finite state machine is constructed from the regular expression contained in
the array of charT of length char_traits::length(p) whose first element
is designated by p, and interpreted according to the flags f.
Postconditions: flags() returns f. mark_count() returns the number of marked
sub-expressions within the expression.
...

As of now, std::basic_regex implementation disagrees with the standard in that
the flags set upon construction aren`t equal to the flags passed to the
constructor.

Reproducer:

#include 
int main() {
std::basic_regex ca("(a)(b)", std::regex_constants::icase);
std::basic_regex cb("(a)(b)", std::regex_constants::nosubs);
std::basic_regex wa(L"(a)(b)", std::regex_constants::icase);

[Bug libstdc++/83600] New: std::match_results C++14 conformance issue: iterators not equal

Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: libstdc++

  Reporter: andrey.y.guskov at intel dot com
  Target Milestone: ---

C++14 Standard (see here:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf), section
28.10:

The class template match_results shall satisfy the requirements of an
allocator-aware container and of a sequence container, as specified in 23.2.3


Container requirements, section 23.2.1:

Expression: a.empty() 
Return type: convertible to bool
Operational semantics: a.begin() == a.end()


Section 24.7:

template  auto begin(C& c) -> decltype(c.begin());
template  auto begin(const C& c) -> decltype(c.begin());
Returns: c.begin().
template  auto end(C& c) -> decltype(c.end());
template  auto end(const C& c) -> decltype(c.end());
Returns: c.end().


Creating an empty instance of match_results container and then comparing
its begin and end iterators results in a mismatch, whereas according to the
standard they have to be the same:


#include 
int main() {
std::match_results m;
return !printf((std::begin(m) == std::end(m))? "PASS\n" : "FAIL\n");
}

[Bug libstdc++/83601] New: std::regex_replace C++14 conformance issue: escaping in SED mode

[andrey.y.guskov at intel dot com]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83601

Bug ID: 83601
   Summary: std::regex_replace C++14 conformance issue: escaping
in SED mode
   Product: gcc
   Version: 8.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: libstdc++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: andrey.y.guskov at intel dot com
  Target Milestone: ---

C++14 standard (page 1107, see here:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf#1121), 28.5.2
[Bitmask type regex_constants::match_flag_type]:

...
format_sed
When a regular expression match is to be replaced by a new string, the new
string shall be constructed using the rules used by the sed utility in POSIX.
...


The rules which SED uses are documented in IEEE 1003.1 (p. 3221):

An 
('&') appearing in the replacement shall be replaced by the string matching the
BRE. The special meaning of '&' in this context can be suppressed by preceding
it
by a . The characters "\n", where n is a digit, shall be replaced by
the
text matched by the corresponding back-reference expression. 
...
The special meaning of "\n" where n is a digit in
this context, can be suppressed by preceding it by a .


The current implementation of std::regex_replace does not comply to the
standard: special meanings of &, \0, \2 cannot be suppressed by escaping them
with backslashes.


Reproducer:

#include 
int frep(const wchar_t *istr, const wchar_t *rstr, const wchar_t *ostr) {
std::basic_regex wrgx(L"(a*)(b+)");
std::basic_string wstr = istr, wret = ostr, test;

   wrgx, std::basic_string(rstr),
   std::regex_constants::format_sed);
return !printf("'%ls' %c= '%ls'\n",
   test.c_str(), (test == wret)? '=' : '!', wret.c_str());
}
int main() {
frep(L"xbbyabz", L"!2!", L"x!\\2!y!\\2!z");

I`m seeing a miscompare in 628.pop2_s compiled with the following option set:

-m64 -march=core-avx2 -mfpmath=sse -Ofast -funroll-loops -fconvert=big-endian
-fopenmp

The guilty revision is r251230. Despite exp(log(c)*x) being faster, it seems to
lack the precision of pow(c,x).

--- Comment #2 from Andrey Guskov  ---
Approximately a hundred different variables and function calls, the majority of
which are raised to the second or third power, sometimes fourth or fifth. As
628.pop2_s is mostly written in Fortran 90, all of the cases look like c**x.
I`m not sure if this gets transformed into pow() when x is constant, though.

As for the cases where x is either not constant or non-integer, there are 22 of
them:

co2calc.F90:  x1(i) = c10 ** (-phhi(i))
co2calc.F90:  x2(i) = c10 ** (-phlo(i))

ecosys_mod.F90:   Tfunc = Q_10**(((TEMP + T0_Kelvin)-(Tref +
T0_Kelvin))/c10)
ecosys_mod.F90:   zoo_loss = z_mort2 * Zprime**1.4_r8 + z_mort * Zprime
ecosys_mod.F90:   TfuncS = 2.5_r8**(((TEMP + T0_Kelvin) - (Tref +
T0_Kelvin)) / c10)

hmix_del4.F90:AMF(:,:,iblock) = (UAREA(:,:,iblock)/uarea_equator)**1.5
hmix_del4.F90:AHF(:,:,iblock) = (TAREA(:,:,iblock)/uarea_equator)**1.5

hmix_gm.F90:  BOLUS_SP(:,:,bid) = 50.0_r8 * sqrt(U_ISOP**c2 +
V_ISOP**c2)

overflows.F90:phi = c1-Fgeo**(-c2/c3)

seq_flux_mct.F90: anidr = (.026_R8/(cosz**1.7_R8 + 0.065_R8))
shr_flux_mod.F90: temp = (zkB*zkB)**(1.0_R8/a2) ! note: zkB < 0, zkB*zkB >
0
shr_flux_mod.F90: temp = (zeta*zeta)**(1.0_R8/a2) ! note: zeta < 0,
zeta*zeta > 0

state_mod.F90:st15 = salt**(1.5_r8)

sw_absorption.F90:chlamnt = 10**(logchl)

time_management.F90:  ifact = 10**(string_length - n)

vmix_kpp.F90: cg = cstar*vonkar*(c_s*vonkar*epssfc)**p33
vmix_kpp.F90: bckgrnd_vdc_psis=
bckgrnd_vdc_psim*exp(-(0.4_r8*(tlatd+28.9_r8))**c2)
vmix_kpp.F90: bckgrnd_vdc_psin=
bckgrnd_vdc_psim*exp(-(0.4_r8*(tlatd-28.9_r8))**c2)
vmix_kpp.F90: bckgrnd_vdc1 * (tlatd/10.0_r8)**c2
vmix_kpp.F90: WM(i,j) = vonkar*USTAR(i,j)*(c1 - c16*ZETA(i,j))**p25
vmix_kpp.F90: WM(i,j) =
vonkar*(a_m*(USTAR(i,j)**3)-c_m*ZETAH(i,j))**p33
vmix_kpp.F90: WS(i,j) =
vonkar*(a_s*(USTAR(i,j)**3)-c_s*ZETAH(i,j))**p33


...Something tells me I didn`t get the question.

--- Comment #4 from Andrey Guskov  ---
Okay, finally I`ve got a minimal reproducer.
All this miscompare boils down to the following:

program r628
real(8) :: l = -3
print *, merge("PASSED", "FAILED", 1D-3 .le. 10**l)
end program r628

Normally, 10^-3 should equal 10^-3, but not after the optimization in question.

$ gfortran -m64 -O3 -o r628 r628.f90 && ./r628

--- Comment #5 from Andrey Guskov  ---
This is the actual guilty line:

sw_absorption.F90:chlamnt = 10**(logchl)

It computes 'chlamnt' and then compares it to the list of acceptable values.
When -Ofast is enabled, CPU2017::628 considers 'chlamnt' unacceptable.

Also seeing this. Investigating.

Preliminarily, this has something to do with transposing matrices (M1 =
transpose(M2)) when either M1 or M2 is defined as Real(4), Pointer, Save.

Okay, testing complete.
The performance delta is less than 1% (0.96% to be exact), but technically the

--- Comment #2 from Andrey Guskov  ---
Well, it is actually a bisection. Do I need to rule out a GDB problem?
GDB on our testing machine is as follows:

$ gdb -v | grep GDB
GNU gdb (GDB) Fedora 7.10.1-31.fc23
This GDB was configured as "x86_64-redhat-linux-gnu".
