[Bug bootstrap/70420] New: (Building GCC) mtune=native and internal compiler error at emit-rtl.c:1027
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70420 Bug ID: 70420 Summary: (Building GCC) mtune=native and internal compiler error at emit-rtl.c:1027 Product: gcc Version: 5.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap Assignee: unassigned at gcc dot gnu.org Reporter: xsetech at gmail dot com Target Milestone: --- I'm compiling GCC 5.3.0 for OS X. Specifically compiling it for: OS X El Capitan 10.11.3 Intel(R) Core(TM) i5-4258U CPU @ 2.40GHz The following command-line causes an internal compiler error: CFLAGS_FOR_BUILD="-march=native -mtune=native" CXXFLAGS_FOR_BUILD="-march=native -mtune=native" CFLAGS="-march=native -mtune=native -mfpmath=sse" CPPFLAGS="-march=native -mtune=native -mfpmath=sse" ../configure --prefix=/home/setech/Local/usr/local/ --with-mpc=/home/setech/Local/usr/local/ --with-gmp=/home/setech/Local/usr/local/ --with-mpfr=/home/setech/Local/usr/local/ --with-isl=/home/setech/Local/usr/local/ --enable-languages=c,c++ -v && make -j 3 Without the -mtune and -march options, make completes without verbal error. The exact place of error is: ../../../../libquadmath/math/rem_pio2q.c:587:1: internal compiler error: in gen_reg_rtx, at emit-rtl.c:1027 Some context in the compilation process: xgcc: internal compiler error: Abort trap: 6 (program cc1) Please submit a full bug report, with preprocessed source if appropriate.
