Subject: ggml : use noexcept overload for is_regular_file in backend registration (#19452)
X-Git-Tag: upstream/0.0.8067~80
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=6948adc90d77949e7802616d4c030396cf03b9c7;p=pkg%2Fggml%2Fsources%2Fllama.cpp

ggml : use noexcept overload for is_regular_file in backend registration (#19452)

using noexcept std::filesystem::directory_entry::is_regular_file
overload prevents abnormal termination upon throwing an error
(as caused by symlinks to non-existent folders on linux)

Resolves: #18560
