Tested cris-elf and native x86_64-pc-linux-gnu. Ok to commit? ---- 8< ---- The use of a "naked" int32_t (i.e. without a fitting #include: stdint.h or cstdint or inttypes.h or an equivalent internal header), in libstdc++-v3/include/pstl/unseq_backend_simd.h, caused an error for cris-elf and apparently pru-elf and I guess all "newlib targets". (Unfortunately, there's a lack of other *-elf targets in recent months of gcc-testresults archives.)
This does not manifest on e.g. native x86_64-pc-linux-gnu, because there, a definition is included as an effect of including stdlib.h in cstdlib (following the trace in native xtreme-header-2_a.ii with glibc-2.31-13+deb11u5). Maybe better than chasing the right #includes is to directly use the built-in type, like so: libstdc++-v3: PR libstdc++/108672 * include/pstl/unseq_backend_simd.h (__simd_or): Use __INT32_TYPE__ instead of int32_t. --- libstdc++-v3/include/pstl/unseq_backend_simd.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libstdc++-v3/include/pstl/unseq_backend_simd.h b/libstdc++-v3/include/pstl/unseq_backend_simd.h index a05de39f7576..f6265f5c16e5 100644 --- a/libstdc++-v3/include/pstl/unseq_backend_simd.h +++ b/libstdc++-v3/include/pstl/unseq_backend_simd.h @@ -74,7 +74,7 @@ __simd_or(_Index __first, _DifferenceType __n, _Pred __pred) noexcept const _Index __last = __first + __n; while (__last != __first) { - int32_t __flag = 1; + __INT32_TYPE__ __flag = 1; _PSTL_PRAGMA_SIMD_REDUCTION(& : __flag) for (_DifferenceType __i = 0; __i < __block_size; ++__i) if (__pred(*(__first + __i))) -- 2.30.2
