[ACTIVITY] report week ending 3 Sep

by Peter Maydell

Progress (short week, 2 days) * UM-2 [QEMU upstream maintainership] + Lots of code review and getting things upstream after trunk reopened + Wrote up a first draft of how to handle merging pullreqs, so that other people can share this job with me + Sent a patchset that allows board models to mark some buses as not suitable for plugging in user-created devices -- this avoids problems with i2c devices appearing on buses that are supposed to be for on-board devices only in the MPS2/MPS3 machines * QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)] + MVE is now enabled upstream. (There are still some loose ends to do under this JIRA task, though.) + Sent a patchset that makes some of the easier codegen optimizations for the no-predication case. (Code review spotted an issue which might be painful to sort out -- we'll see next week...) -- PMM

[CI-NOTIFY]: TCWG Bisect tcwg_gcc_bootstrap/master-arm-bootstrap_O3 - Build # 2 - Successful!

by ci_notify＠linaro.org

Successfully identified regression in *gcc* in CI configuration tcwg_gcc_bootstrap/master-arm-bootstrap_O3. So far, this commit has regressed CI configurations: - tcwg_gcc_bootstrap/master-arm-bootstrap_O3 Culprit: <cut> commit cad36f38576a6a781e3c62ab061c68f5b8dab13a Author: Roger Sayle <roger(a)nextmovesoftware.com> Date: Tue Aug 31 11:45:07 2021 +0100 Preserve SUBREG_PROMOTED_VAR_P on (extend:HI (subreg/s:QI (reg:SI))). SUBREG_PROMOTED_VAR_P is a mechanism for tracking that a partial subreg is correctly zero-extended or sign-extended in the parent register. For example, the RTL (subreg/s/v:QI (reg/v:SI 23 [ x ]) 0) indicates that the byte x is zero extended in reg:SI 23, which is useful for optimization. An example is that zero extending the above QImode value to HImode can simply use a wider subreg, i.e. (subreg:HI (reg/v:SI 23 [ x ]) 0). This patch addresses the oversight/missed optimization opportunity that the new HImode subreg above should retain its SUBREG_PROMOTED_VAR_P annotation as its value is guaranteed to be correctly extended in the SImode parent. The code below to preserve SUBREG_PROMOTED_VAR_P is already present in the middle-end (e.g. simplify-rtx.c:7232-7242) but missing from one or two (precisely three) places that (accidentally) strip it. Whilst there I also added another optimization. If we need to extend the above QImode value beyond the SImode register holding it, say to DImode, we can eliminate the SUBREG and simply extend from the SImode register to DImode. 2021-08-31 Roger Sayle <roger(a)nextmovesoftware.com> gcc/ChangeLog * expr.c (convert_modes): Preserve SUBREG_PROMOTED_VAR_P when creating a (wider) partial subreg from a SUBREG_PROMOTED_VAR_P subreg. * simplify-rtx.c (simplify_unary_operation_1) [SIGN_EXTEND]: Likewise, preserve SUBREG_PROMOTED_VAR_P when creating a (wider) partial subreg from a SUBREG_PROMOTED_VAR_P subreg.

[CI-NOTIFY]: TCWG Bisect tcwg_bmk_tk1/llvm-master-arm-spec2k6-O2 - Build # 11 - Successful!

Successfully identified regression in *llvm* in CI configuration tcwg_bmk_llvm_tk1/llvm-master-arm-spec2k6-O2. So far, this commit has regressed CI configurations: - tcwg_bmk_llvm_tk1/llvm-master-arm-spec2k6-O2 Culprit: <cut> commit 92c1fd19abb15bc68b1127a26137a69e033cdb39 Author: Stanislav Mekhanoshin <Stanislav.Mekhanoshin(a)amd.com> Date: Thu Aug 19 11:42:09 2021 -0700 Allow rematerialization of virtual reg uses Currently isReallyTriviallyReMaterializableGeneric() implementation prevents rematerialization on any virtual register use on the grounds that is not a trivial rematerialization and that we do not want to extend liveranges. It appears that LRE logic does not attempt to extend a liverange of a source register for rematerialization so that is not an issue. That is checked in the LiveRangeEdit::allUsesAvailableAt(). The only non-trivial aspect of it is accounting for tied-defs which normally represent a read-modify-write operation and not rematerializable. The test for a tied-def situation already exists in the /CodeGen/AMDGPU/remat-vop.mir, test_no_remat_v_cvt_f32_i32_sdwa_dst_unused_preserve. The change has affected ARM/Thumb, Mips, RISCV, and x86. For the targets where I more or less understand the asm it seems to reduce spilling (as expected) or be neutral. However, it needs a review by all targets' specialists.

The test for a tied-def situation already exists in the /CodeGen/AMDGPU/remat-vop.mir, test_no_remat_v_cvt_f32_i32_sdwa_dst_unused_preserve. The change has affected ARM/Thumb, Mips, RISCV, and x86. For the targets where I more or less understand the asm it seems to reduce spilling (as expected) or be neutral. However, it needs a review by all targets' specialists.
