Bug ID: 121975
Summary: Various goacc failures with
-ftrivial-auto-var-init=zero
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
I'm working now on a patch for PR114457 which will kind of enable
-ftrivial-auto-var-init=zero for -std=c++26 by default.
I've run into various FAILs in goacc testsuite and it is reproduceable also
with vanilla trunk with
make check-c++
