Functions in <string> incorrectly return NULL |
Fixed |
ARM_18.9.0.STS |
ARM_18.9.0.STS |
Ignore or suppress the warning. |
char_traits<char>::find() and char_traits<wchar_t>::find()
return char* and wchar_t*, respectively. In our __string file (included
by <string>), they are written to return NULL, which is (void*)0 and
not the same type as the declaration, thus producing a warning. We have
updated the file to make them return 0, which fixes the warnings. |

Including stddef.h may disable MISRA diagnostics |
Fixed |
ARM_18.9.0.STS |
ARM_18.9.0.STS |
Add "#pragma diag_pop" after the inclusion of these files. SInce
they're sometimes included from other system include files, it may take
some digging to realise that this is necessary. |
Two include files -- stddef.h and string.h -- each lacked one diag_pop
pragma to match the diag_push pragma, which meant that including those
files would inadvertently disable certain MISRA warnings. |

Macro with temp label causes assembler to crash |
Fixed |
|
ARM_18.9.0.STS |
The problem will not occur without macro labels. If labels are
required, no workaround is known. |
The assembler may crash or report a memory misuse when using an
assembly macro containing a label, if the label appears in an instruction
in a position that requires extra lookahead to parse. The original example
is a register name followed by a comma and a label use; for that
assembler, the thing following the comma might be a shift specifier, so it
requires expanding the macro label. That extra step frees some memory
that it shouldn't, causing the problem. |

When shift counts are higher than 32, compiler sometimes optimizes to
an incorrect shift count |
Fixed |
ARM_18.9.0.STS |
ARM_18.9.0.STS |
Turn off optimization by using optimization level off. Otherwise,
avoid a left-shift by a constant as an operand of the listed operations.
However, compiler optimizations could interfere with this. Try keeping
the shift count in a global variable instead of as a literal, or computing
the shift separately into a variable (a global or volatile local) and
doing the |, +, etc, on the variable. |
Left shifts by 32 or more, as an operand of +, -, &, |, or ^, (eg,
((X<<56) | (Y<<48))) may produce incorrect results. |

Warning when using pragma RETAIN with attribute((noinit)) |
Fixed |
ARM_18.9.0.STS |
ARM_18.9.0.STS |
|
When using pragma RETAIN with attribute((noinit)) on the same symbol
for an EABI target, a .clink directive is erroneously emitted in the
assembly file, leading to a warning that the .CLINK directive is being
ignored because the symbol already has .RETAIN specified. |

Unreachable code in linear assembly may lead to crash |
Fixed |
ARM_18.9.0.STS |
ARM_18.9.0.STS |
Remove the unreachable code before compiling, or compile with -o1,
-o0, or -ooff, or use --symdebug:none which happens to avoid the
problem. |
The compiler may crash if given a linear assembly file containing some
code that has a label but is not reachable. It's theoretically possible
to create the same problem with C/C++ code, but we haven't been able to do
it and the risk is quite small. |

Various standard classes inherit from std::binary_function when they
shouldn't |
Fixed |
|
ARM_18.9.0.STS |
|
According to the synopses of headers in C++14, many classes which do
not inherit from std::binary_function do inherit from it as an
implementation decision. A sample list are object of the following similar
object types: * std::map::value_compare and std::multimap::value_compare *
std::plus * std::owner_less |

std::binomial_distribution references undefined function lgamma_r |
Fixed |
|
ARM_18.9.0.STS |
|
Instantiations of std::binomial_distribution fail to link due to the
undefined symbol lgamma_r. This is a C11 function which is not provided by
the TI C library. |

Auto thread_local variable is causing a reference to
__cxa_thread_atexit |
Fixed |
|
ARM_18.9.0.STS |
|
The thread_local specifier, when applied to variables, should
currently be ignored because we only support single-threaded environments.
However, a global variable with the thread_local specifier, if requiring
dynamic initialization, will cause a reference to the standard ABI
function __cxa_thread_atexit that can't be resolved by the linker. |

Stack usage under reports stack amount used because it fails to handle
function aliases |
Fixed |
|
ARM_18.9.0.STS |
|
CCS Stack Assistant did not accurately track aliased functions--
functions whose definitions are represented by a different symbol name.
Now, the alias function will be used to determine stack size correctly,
and the aliased function call name will be replaced with its alias.
Currently, the Stack Assistant GUI is not capable of showing both the
aliased and alias function names for calls to aliased functions-- this
will require a future update. |
