This is a draft version of a MISRA C++ 202x rule proposed for public review.
MISRA Rule 5.7.3
Category: Required
Analysis Type: Decidable,Single Translation Unit
Amplification
This rule is applied in translation phase 2, after multibyte characters have been mapped to the basic source character set during translation phase
1 (see [lex.phases]).
Rationale
Line-splicing occurs when the \ character is immediately followed by a new-line character. If a source line containing a
// comment ends with a \ character in the basic source character set, the next line becomes part of the comment. This may
result in the unintentional removal of code.
Example
In the following non-compliant example, the physical line containing the if keyword is logically part of the previous line and is
therefore part of a comment.
void f( bool b )
{
uint16_t x = 0U; // comment \
if ( b )
{
++x; // This is always executed
}
}
