2025-03-28	stdio-common: Reject integer prefixes in scanf [BZ #12701]	Maciej W. Rozycki	1	-48/+48
	Reject invalid formatted scanf integer input data that is comprised of a binary or hexadecimal prefix, optionally preceded by a sign, and with no actual digits following. Such data is a prefix of, but not a matching input sequence and it is required by ISO C to cause a matching failure. Currently a matching success is instead incorrectly produced along with the conversion result of zero, with the prefix wholly consumed from input. Enable input data that causes test failures without this fix in place. Reviewed-by: Joseph Myers <josmyers@redhat.com>
2025-03-25	stdio-common: Add scanf integer data for LP64 targets	Maciej W. Rozycki	1	-0/+644
	Add Makefile infrastructure and `int' and `long' integer input data, signed and unsigned, for LP64 targets. While the size of `int' data is the same between ILP32 and LP64 targets, resulting scanf output is different between them for out of range input data and while ISO C and POSIX both say that the behavior is undefined if the result of the conversion cannot be represented we want to keep track of our output to prevent inadvertent changes. Hence the use of distinct `int' integer input data between ILP32 and LP64 targets. Keep input data disabled and referring to BZ #12701 for entries that are are currently incorrectly accepted as valid data, such as '0b' or '0x'. Reviewed-by: Joseph Myers <josmyers@redhat.com>
