preprocessed source

seen with the current gcc-5-branch, as well with a cross compiler, -O2 works, 4.9 and trunk work as well.

$ s390x-linux-gnu-gcc -std=c99 -Wall -march=zEC12 -O2 -c  tiny_psnr.i
Comment 1 Jakub Jelinek 2016-01-16 11:44:41 UTC 
Killed just means you don't have enough memory.  So, if there is some regression, it would be only if compiling the same preprocessed source takes unreasonably more memory compared to older (or in this case also newer) gcc.
Comment 2 Matthias Klose 2016-01-16 11:50:11 UTC 
4.9 and 6 build within under a second, I didn't even look at the memory usage.  5 was killed automatically on a VM with 8G RAM + 6G swap; killed the cross build manually when reaching 16GB.
Comment 3 Matthias Klose 2016-01-16 11:50:57 UTC 
sorry, that should be -O3:

s390x-linux-gnu-gcc -std=c99 -Wall -march=zEC12 -O3 -c  tiny_psnr.i
Comment 4 Richard Biener 2016-06-03 10:05:37 UTC 
GCC 5.4 is being released, adjusting target milestone.

auto-reduced testcase

Fails with -O3 -march=z196. Endless loop in VRP with GCC 5. Works fine with GCC 6 branch.
Comment 6 Jakub Jelinek 2017-10-10 14:22:17 UTC 
GCC 5 branch has been closed, should be fixed in GCC 6 and later.
