Bug ID: 68675
Summary: Handle GOMP_target_ext optimally in ipa-pta
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg01336.html :
...
What we can and should improve is teach IPA aliasing/points to analysis
about the way we lower the host vs. offloading region boundary, so that
if alias analysis on the caller of GOMP_target_ext/GOACC_parallel_keyed
determines something it can be used on the offloaded function side and vice
versa.
...
GOACC_parallel_keyed has been implemented, todo: GOMP_target_ext
