Here is the caller graph for this function:

qtWarnAboutInvalidRegularExpression()

Q_DECL_COLD_FUNCTION void qtWarnAboutInvalidRegularExpression	(	const QString &	pattern,
		const char *	where )

Used to centralize the warning about using an invalid QRegularExpression. In case the pattern is an illegal UTF-16 string, we can't pass print it (pass it to qUtf16Printable, etc.), so we need to check for that.

safe_pcre2_match_16()

static int safe_pcre2_match_16 ( const pcre2_code_16 * code, PCRE2_SPTR16 subject, qsizetype length, qsizetype startOffset, int options, pcre2_match_data_16 * matchData, pcre2_match_context_16 * matchContext )

static

This is a simple wrapper for pcre2_match_16 for handling the case in which the JIT runs out of memory. In that case, we allocate a thread-local JIT stack and re-run pcre2_match_16.
