single .ii file that triggers the ICE
Hi,
Trying out current Debian's gcc-snapshot (20140708) with a code that compiled
fine with gcc-snapshot from a few weeks ago, I got:
internal compiler error: in lra_update_insn_recog_data, at lra.c:1219
Sorry, but I have no time now to narrow the cause :(
It can be reproduced with the attached .ii file and
/usr/lib/gcc-snapshot/bin/g++ -std=c++11 -fopenmp -pthread -Wfatal-errors
-DNDEBUG -Ofast -march=native over_the_pole_2d.ii
The native march seems to mean here (echo | /usr/lib/gcc-snapshot/bin/gcc -###
-E - -march=native):
