GCC becomes slower and slower
Thursday, January 18th, 2018As visible on my other posts, also on twitter and instagram I’m working on some vintage machines with our #t2sde the other weeks. Now only did the new GCC versions feel slower and slower, where even EPYC datacenter servers took like twice as long to bootstrap some $sysroot, … I did a quick mips64 build and install to the R10000 mips64 Sgi Octane. A hello-world.c compile is like 20% slower from 4.9.4 to 7.2.0 (N32 user-land):
# gcc –version
gcc (GCC) 4.9.4
# time gcc hello.c
user 0m1.080svs.
# gcc –version
gcc (GCC) 7.2.0
# gcc hello.c
user 0m1.290s
