runtime failure on unaligned access (on some processor variants, not all) |
Open |
ARM_18.1.0.LTS |
|
|
The following code results in an unaligned access failure in the ARM simulator when compiled with:
armcl -mv5e -me --float_support=vfpv2
#include <map>
#include <stdio.h>
int main(void)
{
std::map<int, char>::size_type n=9;

Internal error when passing a temporary array of objects |
Accepted |
ARM_18.1.0.LTS |
|
|
The following example code exhibits an internal compiler error caused by passing a temporary C array as an argument to a function taking an rvalue reference to an array:
struct S {
int m;
S(int i=1) : m(i) {}
operator int() { return m; }
int operator +(const S& r) { return m+r.m; }
};
int f00(S (&&r)[3]) { return r[0] + r[1] + r[2]; }
int main(void) {
int g;
S a(97), b(2), c(1);
g = f00({a, b, c});
} |
| CODEGEN-4297 |
Cannot take the address of std::ctype<char>::table_size |
Open |
ARM_18.1.0.LTS |
|
|
This is a defect in the library. The table_size field is declared as having a constant value in the class definition, but there is no one definition for the field in the library.
Taking the address of this field will result in a link-time error. |
| CODEGEN-4296 |
Undefined symbol isblank with -g or -ooff |
Open |
ARM_18.1.0.LTS |
|
|
The C99 function 'isblank' from ctype.h is provided as an inline definition when optimization is turned on, but there is no definition when optimization is turned off, leading to a link-time failure. |

Unexpected type returned by bitset [] operator |
Open |
ARM_18.1.0.LTS |
|
|
The operator[] definition for std::bitset returns a const reference to an internally defined class type, rather than a bool as required by C++14 section 20.6.2 |
| CODEGEN-4276 |
std::multimap::clear is not noexcept |
Open |
ARM_18.1.0.LTS |
|
|
The library does not declare std::multimap::clear as noexcept, which is required by C++14 section 23.4.5.1 paragraph 2 |
| CODEGEN-4275 |
std::num_get does not parse floating-point strings correctly |
Open |
ARM_18.1.0.LTS |
|
|
The C++ library locale helper, std::num_get, currently fails to correctly parser floating-point values in strings and streams. These calculations will always result in the default value of 0.0 for doubles, and 0.0f for floats.
Please use the C library equivalents, such as sprintf, to perform such operations.

regex_constants::ECMAScript not expected to be 0 |
Open |
ARM_18.1.0.LTS |
|
|
std::regex_constraints is a bitmask type, whose definition can be found in C++14 section 17.5.2.1.3. Paragraph 3 of this definition states that all values in the bitmask must be nonzero, so that zero can be used as a special 'empty bitmask' value.
The current implementation assigns std::regex_constraints::ECMAScript to 0, which goes against the definition. |
| CODEGEN-4248 |
armcl allows non-default arguments to be specified after default arguments |
Open |
ARM_18.1.0.LTS |
|
|
The following code should emit a syntax error due to the specification of a second, non-defaulted argument after a defaulted argument. However, the compiler will abort with an internal error.
extern void foo(int, int);
void f() {
auto l = [](int i=1, int j) { foo(i, j); };
l();
} |
| CODEGEN-4247 |
Internal error when assigning default arguments to a parameter pack |
Open |
ARM_18.1.0.LTS |
|
|
The C++14 standard explicitly prohibits assigning default arguments to a
template parameter pack. However, the compile accepts such code silently, and may result in an internal error during compilation.
template <class... Types> void f(Types... args) {
auto lm = [](Types... = args...) {};
lm(10); // internal error here
}
int main() { f(1, 23); return 0; } |

Multiple non-variables may be declared using auto or decltype(auto) |
Open |
ARM_18.1.0.LTS |
|
|
C++14 Section 7.1.6.4 paragraph 8 states that if multiple declarators are on the same line as an auto or decltype(auto) specifying, they must all be variable declarations.
However, our implementation does not enforce this requirement, allowing constructs of the following form:
auto f(void)->int, g(void)->char; |

Parser errors on empty enum declaration |
Open |
ARM_18.1.0.LTS |
|
|
The following code causes an error.
enum : bool { };
While both gcc and clang mark this with a warning, our compiler marks it as an error, due to the declaration being functionally useless and most likely unintentional. |

cannot find matching "==" operator definition |
Open |
ARM_18.1.0.LTS |
|
|
The library does not provide an definition of std::operator== for arguments of type std::istream_iterator. That is, the following code is erroneously marked as ill-formed with a diagnostic:
#include <iterator>
#include <string>
using ISTREAM_ITER_C = std::istream_iterator<char, char>;
bool foo(const ISTREAM_ITER_C& arg00 ,const ISTREAM_ITER_C& arg01 ){
return std::operator== (arg00, arg01); // Syntax error
}
However, this is only an issue if called in exactly that way. Using it as an operator, rather than as a function call, works as expected:
arg00 == arg01 // Works |

Composing operations for valarray may fail to compile |
Open |
ARM_18.1.0.LTS |
|
|
Due to a potential implementation issue in the libc++ library, utilizing the valarray class and composing a result via multiple operations may fail.
For example:
const std::valarray<float> cl(6);
std::slice arg1(0,0,0);
std::slice slice(0,0,0);
cl[arg1][slice]; // Compilation error! |
| CODEGEN-4091 |
Incomplete class type when using various members of <iterator> |
Open |
ARM_18.1.0.LTS |
|
|
The following code sample results in an incomplete type error:
#include <iterator>
int main(void)
{
bool always_false = false;
if (always_false) {
std::istreambuf_iterator<char> cl;
std::istreambuf_iterator<char> var1;
const std::istreambuf_iterator<char> & arg1 = var1;
(void) cl.equal(arg1);
}
return 1;
}
The question is whether including <iterator> ought to include <streambuf>, which includes the definition for std::basic_streambuf, which is required by the definition of std::istreambuf_iterator. |

Unimplemented core issue 475: std::uncaught_exception is not true when constructing the thrown object |
Open |
ARM_18.1.0.LTS |

In the code below, std::uncaught_exception should be true when constructing the A object that is constructed to be propagated to the catch block. The current implementation returns false.
#include <exception>
#include <assert.h>

Unimplemented core issue 1769: Catching a thrown derived class by reference to base clas |
Open |
ARM_18.1.0.LTS |

Core 1769, involving a resolution which states that derived classes can be thrown and caught by catch clauses denoting an unambiguous base, has not been implemented.
#include <assert.h>

Due to an implementation detail, the <regex> header will never throw an exception corresponding to std::regex_constants::error_ctype. This can be exhibited from the below code sample:
#include <regex>
int main(void) {
try {
std::regex e("[[:not_a_class:]]", std::regex_constants::ECMAScript);
std::regex_match("a", e);
}
catch(std::regex_error e){

libcxx istreambuf_iterator points to end of string instead of character past match |
Open |
ARM_18.1.0.LTS |
|
|
The C++11 standard says that the "iterator is always left pointing one position beyond the last character successfully matched." In this case, that's after zero characters, so the iterator should point to the first character, just as the test expects. However, libcxx doesn't do this; it returns the pointer to the end of the string, which is indeed composed of characters that might match a (hex) float, but that's not the final word.
The libc++ code has advanced the iterator to "end," which it should not have done because the input sequence did not match. The test case expects the match to fail, leaving an iterator pointing to something other than "end," and it dereferences the iterator; because the iterator is actually "end", we get a NULL pointer dereference and hilarity ensues.
I claim this is a flaw in the the libc++ implementation.
cutdown test case:
#include <locale>
#include <sstream>
typedef std::char_traits<char> test1;
typedef std::istreambuf_iterator<char, test1> istr_it;
struct mynum : public std::num_get<char, istr_it>
{
iter_type my_do_get(iter_type first, iter_type last, std::ios_base& str,
std::ios_base::iostate& st, bool& val) const
{ return (do_get(first, last, str, st, val)); }
};
int main()
{
mynum my_num_get;
std::ios_base::iostate st = std::ios_base::goodbit;
std::istringstream istr("abcdef");
istr_it first(istr.rdbuf()), last;
st = std::ios_base::goodbit;
double dv = 0;
if(*(first = my_num_get.get(first, last, istr, st, dv)) == 'a')
return 1;

Compiler allows constant subtraction between pointers to different objects |
Open |
ARM_18.1.0.LTS |
|
|
The compiler allows the following code without error:
struct STR {
constexpr STR(): arr1{1,2}, arr2{3,4} {};
const char arr1[2];
const char arr2[2];
};
const struct STR str;
constexpr char const *ptr1 = str.arr1;
constexpr char const *ptr3 = str.arr2;
constexpr int diff2 = ptr3 - ptr1;
The definition of diff2 subtracts pointers to different objects, and should be disallowed. |

Access of const static member through pointer is not a constant expression. |
Open |
ARM_18.1.0.LTS |

|
The compiler emits an arguably spurious error on an access of a const static data member through a pointer when a constant expression is required. While gcc allows this silently, both the TI compiler and clang emit errors in stricter modes.
struct C { const static int m; };
const int C::m = 4;
C c, *cp = &c;
int main(void)

struct S02 {
int x : cp->m; // error, not a constant expression

Unimplemented core issue 588: Unqualified name lookup examines dependent base class |
Open |
ARM_18.1.0.LTS |

Similar to core issue 591 and CODEGEN-3963, this core issue resolves a lookup issue in a function template.
In the following source code, the struct 'A' will examine the scope of the base class D<T> to resolve the unqualified reference to B, when the core issue resolution states that D<T> should be skipped and the B found in the function template 'g' should be used instead.
struct B{ void f(int); };
template<class T> struct D: B { };
template<class T> void g() {
struct B { void f(); };
struct A : D<T> {

Unimplemented core issue 1374: Conversion sequence ranks qualification before reference binding |
Open |
ARM_18.1.0.LTS |
|
|
The following code will print B, when both gcc and clang print A. This is due to a resolution to core issue 1374, which reorders the rankings of conversion sequences such that qualification difference are accounted for after reference binding differences, rather than before.
#include <stdio.h>
typedef int * T1;
typedef int *const T2;
void foo(T1 &) { printf("A\n"); } // (1)
void foo(T2 &&) { printf("B\n"); } // (2)

Unimplemented core issue 1951: cv-qualified void and scalar types are not literal types |

std::rethrow_if_nested does not have standard signature |
Open |
ARM_18.1.0.LTS |
|
|
The standard states that std::rethrow_if_nested have the signature:
template <class E> void rethrow_if_nested(const E& e); // C++14 18.8.6 p9
The library implementation adds a second paramter to its definition of the function for the purpose of utilizing SFINAE.
This only affects uses of std::rethrow_if_nested if attempting to describe its signature as a type. As an example, the following attempt to capture the function pointer in a variable will fail to compile:
void (*p)(const int&) = &std::rethrow_if_nested<int>; |

#pragma LOCATION and palign do not work together |
Open |
ARM_18.1.0.LTS |
|
One workaround is to use specific placement in the linker command file. In the C code, replace the #pragma LOCATION with a #pragma DATA_SECTION ...
#pragma DATA_SECTION(device_fw_info_ptr, "for_device");
And in the linker command file, replace the whole .TI.bound line with this ...
for_device > 0x00018000, palign(8), fill = 0xffffffff

If using the TI compiler, the TI compiler doesn't call any of these functions, so no workaround should be necessary.

Structure is not initialized correctly when using -o2 or -o3 optimization |
Accepted |
ARM_18.1.0.LTS |

The initialization will have to be done at run-time, through a __sti initialization routine. You can see this routine when compiling without optimization. To workaround the compiler removing this initialization routine, initialize the object at the beginning of main:
Info2.mSize = ((unsigned)_end_isr_stack - (unsigned)_start_isr_stack);

DWARF does not correctly represent variables stored in register pairs |
Planned |
ARM_18.1.0.LTS |
|
Although 'var1' and 'var2' are shown to be in single registers, a
debugger could determine that they are actually stored in register
pairs by looking at the type of the variables:
[00000113] DW_TAG_base_type
DW_AT_name long long
DW_AT_encoding 0x5
DW_AT_byte_size 0x8
The base type indicates that the size of the variables is 0x8 bytes.
Since a single register can only store 0x4 bytes of information, it
would take two registers to hold this values.
On TI architectures, values stored in multiple registers are always
stored in consecutive registers. Thus, the debugger would know that
if the entire value could not fit in A4, the rest of the value must be
in A5. A5 would contain the upper 32 bits of the value.
