https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86684 --- Comment #13 from Segher Boessenkool --- Author: segher Date: Fri Aug 31 08:52:13 2018 New Revision: 264011 URL: https://gcc.gnu.org/viewcvs?rev=264011&root=gcc&view=rev Log: rs6000: Make lrounddi2 depend on TARGET_FPRND (PR86684) TARGET_FPRND should be on for everything ISA 2.04 and later, and TARGET_VSX implies ISA 2.06 or later; but it is possible to disable TARGET_FPRND (separately via -mno-fprnd, but also implicitly) currently, and then things fall down. This patch makes things not fall down. PR target/86684 PR target/87149 * config/rs6000/rs6000.md (lrounddi2): Gate on TARGET_FPRND. Modified: trunk/gcc/ChangeLog trunk/gcc/config/rs6000/rs6000.md

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86684 --- Comment #12 from Segher Boessenkool --- So, ignoring all the configury stuff: the problem is that TARGET_VSX does not imply TARGET_FPRND. It should.

Download latest tarbal and: $ ../configure --enable-languages=c,c++,fortran --disable-multilib --prefix=/home/marxin/bin/gcc2 --disable-bootstrap --disable-libsanitizer --target=ppc64le-linux-gnu $ make -j8 all-host -k CFLAGS="-O0 -g" CXXFLAGS="-O0 -g" $ ./xgcc -B. /home/marxin//gcc/gcc-master/gcc/testsuite/gfortran.dg/bounds_check_19.f90 Should be visible.
