# Disable native compilation. trunk is my daily driver, and I
# update it regularly, so eln-cache grows a new subdir with every
# update.
#
# I have tried it out unwittingly because as distros start
# enabling it, libgccjit becomes part of Emacs build dependencies;
# hence package managers install libgccjit when I ask for these
# build dependencies, and 'configure' defaults to enabling native
# compilation if libgccjit is available.
#
# I am happy to report that on this workstation, native-comp seems
# to Just Workβ’: I remember seeing a grand total of one (1)
# compilation-warning popup over the couple of months I have been
# using it. So congrats to the devs for a smooth UX π
#
# Vibes-wise, I have not noticed performance improvements though.
# When Emacs feels "slow" to me, it is usually because the UI is
# completely unresponsive due to synchronous jobs: e.g. Gnus IMAP
# refresh, fontconfig matching, project-wide regexp search.
#
# So I bow out of native-comp, to avoid the eln-cache spill.
