I've configured R-devel with
--enable-lto LTO="-flto=thin" LTO_FC="" LTO_LD="-Wl,-mllvm,-threads=4"
and built with tools from Xcode 15.3. R CMD check --as-cran emits
* checking for detritus in the temp directory ... NOTE
Found the following files/directories:
'thinlto-197f23' 'thinlto-1e920d' 'thinlto-9cf7f8' 'thinlto-a5ab80'
'thinlto-b85e70' 'thinlto-bd46e8' 'thinlto-c56505'
which seems spurious. Should tools:::.check_packages be adjusted to either
remove or ignore these? I'm aware that locally I can do
_R_CHECK_THINGS_IN_TEMP_DIR_EXCLUDE_="^thinlto-[0-9a-z]{6}$"
but I figured that I would report anyway ...
