Bug ID: 69725
Summary: profiledbootstrap failure due to unsats for isl
functions
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
profiledbootstrap fails on powerpc64 due to the errors discussed in bug 65313.
In trying to see if I can get profiledbootstrap to complete successfully on
other targets, I tried x86_64 with the following steps and errors during
stageprofile (in stage_current).
$ /src/gcc/trunk/configure --enable-languages=c,c++,fortran,go,lto,obj-c++
--enable-checking=release
...
$ make -j10 BOOT_CFLAGS='-O2 -flto -fuse-linker-plugin' profiledbootstrap
...
