[Linaro-TCWG-CI] gcc-15-8933-ga264c270fde: 1 regressions on arm
Dear contributor,
Our automatic CI has detected problems related to your patch(es). Please find
some details below.
In arm-eabi v7-a softfp, after:
| commit gcc-15-8933-ga264c270fde
| Author: Giuseppe D'Angelo
| Date: Wed Mar 26 15:30:47 2025 +0100
|
| libstdc++: do not advertise full P2562R1 support
|
| P2562R1 ("constexpr Stable Sorting") adds constexpr to stable_sort,
| stable_partition and inplace_merge. However only the first is already
| implemented in libstdc++, so we shouldn't bump the feature-testing
| ... 12 lines of the commit log omitted.
Produces 1 regressions:
|
| regressions.sum:
| Running libstdc++:libstdc++-dg/conformance.exp ...
| FAIL: 25_algorithms/stable_sort/constexpr.cc -std=gnu++26 (test for excess
errors)
