2025-08-23stdio-common: Convert macros across scanf input specifier testsMaciej W. Rozycki1-8/+10
Convert 'compare_real', 'read_real', and 'verify_input' macros to functions so as to improve readability and avoid pitfalls. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2025-08-23stdio-common: Adjust header inclusion in scanf input specifier testsMaciej W. Rozycki1-2/+4
Move the inclusion of the data class header from the individual tests to the data-type-specific skeleton, providing for the use of the data type under test in the data class header and reducing duplication. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

2025-08-22x86_64: Use __seg_fs qualifiers in NPTL accessorsUros Bizjak4-96/+105
Use __seg_fs named address space qualifiers to cast NPTL accessors to %fs: prefixed addresses. Use volatile access only where strictly necessary. Use existing assembly RSEQ_* accessors for x32 to work around the GCC bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121613 because negative value in __rseq_offset is used as an offset from %fs.
