Subject: [PATCH] c++/103326 - fix ICE in tsubst with VECTOR_CST
Date: Fri, 19 Nov 2021 08:57:01 +0100 (CET) [thread overview]
Message-ID: <n0rr5784-nsss-477n-5134-o8s06po7no2@fhfr.qr> (raw)
This adds missing handling of VECTOR_CST.
Bootstrap and regtest pending on x86_64-unknown-linux-gnu, OK?
Thanks,
Richard.
