Re: [Linaro-TCWG-CI] gcc-15-1500-g1340ddea015: FAIL: 2 regressions on arm
Hi, I looked into this and still don't understand how to reproduce it. The issue as logged in libstdc++.log is a call from find_last_set(simd_mask>) to _MaskImplNeonMixin::_S_to_bits, which calls vpadd_s32 with two [[gnu::vector_size(8)]] int arguments. The CI compiler complains "error: cannot convert '__vector(2) int' to 'int32x2_t'". Why is that an error on your side and not on any compiler I have at hand? https://compiler-explorer.com/z/88WhcM7Kb not an error here. In any case, the new test only exposes an existing issue in the implementation (or its interaction with some variants of GCC?). The change did not introduce a new bug to libstdc++.
