From 1dad3df1e7f3fd73f157f88561ef424b6853d960 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Tue, 5 Dec 2023 17:53:50 +0000 Subject: Restore build with GCC 4.8 to GCC 5 GCC 5 and earlier applied array-to-pointer decay too early, which affected the new attribute namespace code. A reduced example of the construct that the attribute code uses is: struct S { template<__SIZE_TYPE__ N> S(int (&)[N]); }; struct T { int a; S b; }; int a[] = { 1 }; T t = { 1, a }; This was fixed by f85e1317f8ea933f5c615680353bd646f480f7d3 (PR 16333 et al). This patch tries to add a minimally-invasive workaround. gcc/ada/ * gcc-interface/utils.cc (gnat_internal_attribute_table): Add extra braces to work around PR 16333 in older compilers. gcc/ * attribs.cc (handle_ignored_attributes_option): Add extra braces to work around PR 16333 in older compilers. * config/aarch64/aarch64.cc (aarch64_gnu_attribute_table): Likewise.
