When it is requires-clause that is after <typename T> etc. it already has an exception from that as ( can occur in valid C++20 expression there - starting the parameters of the lambda. In C++23 another case can occur, as the parameters with the ()s can be omitted, requires C can be followed immediately by -> which starts a trailing return type.

The problem is ultimately that make_typename_type ignores the tf_keep_type_decl flag when the dependent name is a template-id. This in turn causes the TYPE_DECL check within tsubst <case TYPENAME_TYPE> to fail, and so we end up not passing tf_ignore_bad_quals to cp_build_qualified_type.

clang-aarch64-quick times out on full build

by Galina Kistanova

Dear Linaro Toolchain Working Group, https://lab.llvm.org/buildbot/#/builders/clang-aarch64-quick builder hits a timeout when it builds a clean build. It builds incrementally just fine. Here is an example - https://lab.llvm.org/buildbot#builders/188/builds/1518 The time out is 20 minutes without any TTY, which looks more than enough. Could you investigate on what test it gets stuck and what would be a proper fix, please? Thanks Galina

[ACTIVITY] report week ending 23 July

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] + Noticed we didn't enforce the M-profile "low 2 bits of SP are always 0" rule, and wrote a patch to fix that + Found and fixed a handful of other corner-case M-profile bugs + Some minor docs improvements * QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)] + Implemented the last 4 instruction patterns (VCVT, VRINT), bringing us to Progress: 210/210 (100%) + Found and fixed a few bugs in already-implemented instructions + Started looking at how to make the MVE loads/stores correctly raise alignment faults for unaligned addresses (this runs into problems because QEMU doesn't currently have a good API for doing the load/store the way we want to do it and also handling alignment faults) + Remaining TODO list for this task: - alignment fault behaviour, if not too difficult - report MVE registers via the gdbstub (pending on the XML format being fixed by gdb upstream) - send out patches for code review -- PMM
