riscv64 GCC 14 -> 15 C++ build time regression
Hi,
is it a known issue that with the change from GCC 14 to 15 the build
time of many package increased a lot with C++ code?
I am talking about an increase in the build time of many packages
between 20% and over 100%.
Some code (e.g. Qt) does not seem to be affected.
An example where build time more than doubled in a binNMU:
https://buildd.debian.org/status/logs.php?pkg=opm-simulators&arch=riscv64
On amd64/arm64/mips64el/ppc64el no huge increase happened[1] when
comparing same/similar buildds:
https://buildd.debian.org/status/logs.php?pkg=opm-simulators&arch=amd64
https://buildd.debian.org/status/logs.php?pkg=opm-simulators&arch=arm64
https://buildd.debian.org/status/logs.php?pkg=opm-simulators&arch=mips64el
https://buildd.debian.org/status/logs.php?pkg=opm-simulators&arch=ppc64el

[1] the binNMU was still built with GCC 14 on these architectures,
but -2 should be identical except on ppc64el
