--- Comment #4 from Pekka S <p...@gcc-bugzilla.mail.kapsi.fi> --- (I wrote this prior the ticked was modifed and the patch committed.) Thanks. Applied the patch on the latest trunk, built aarch64-none-gcc cross compiler (mingw64). Using -flto=auto -v reports `LTO parallelism level set to 1' and `make -f <temporary.mk> -j1 all'; Linking now succeeds. Tested using GNU make 4.2.93 and 4.3 (msys2). I do not know whether or not the number of processors should be actually detectable. I presume I'll be simply using -flto=N (N>1) as it appears to work just fine. As a side note behaviour is now slightly different between -flto=auto if nthreads_var<=1 and -flto=N where N<=1.
