Progress: * VIRT-65 [QEMU upstream maintainership] + code review + put together another target-arm pullreq (including more SVE patches) * VIRT-164 [improve Cortex-M emulation] + I have a half-working prototype of small-MPU-regions + sent patches for various preparatory and cleanup work for that + MPC support patchset has been reviewed and needs some minor fixes NB: have shifted next week's non-working day from Weds to Mon due to a meeting on Weds; sorry about the short notice. thanks -- PMM

TCWG-1319 ICF support in clang and lld - Reviewed LLD patches TCWG-1424 Investigate profile information for code-size - Spent some time tracking down problem with using perf=profile and run_under simultaneously. Posted patch upstream. - Investigated how llvm makes use of profile information and found an analysis pass that can be adapted to get the information I'm likely to need. Other - Worked on side-project for tiny-code model. Got it passing the test-suite modulo TLS and one test that was too large for the code model. - Have a good idea of what I'll need to do for TLS, will need to start with assembler support. - Landed https://reviews.llvm.org/D45959 one step closer to removing MCSubargetInfo from assembler backend.

Question About Trusted Application (.ta)

by Yin Liu

Hello, I'm learning the Trusted application that can be run in the TEE. I was wondering whether there are some ways to check the .ta file's instructions, just like using objdump or readelf on ELF. I'm also interested how does the .ta be protected? What's the difference between the .ta and normal executable? Would it be possible to give me some information about that? Thanks in advance! Brs, YL

Aarch64 Toolchain - aarch64-elf-gcc.exe: error: CreateProcess: No such file or directory - additional info

by Glen Verran

Hi there I apologize for posting this again as I was not subscribed to the mailing list on posting my first message, so if the first message made to the list without me being a subscriber, I apologize. I added some more info as to my issue below. I need to cross-compile an application written in C for ARM v8 (aarch64) and found the toolchain on your website. I am running Windows 10 using Cygwin 32-bit as I am already compiling for arm6, arm7 and Linux (x86 and x64) successfully. I downloaded https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-el… and deployed it into my Cygwin installation with no issues. When I ran my script, I get the following error message: aarch64-elf-gcc.exe: error: CreateProcess: No such file or directory I enabled verbose mode on the GCC and the result is below. My Cygwin's default GCC version is 4.8.3, but I am running 7.2.1 for this. I also tried 4.9.4 as well using a different Cygwin instance. Can you please advise how I can get around this error? I am able to cross-compile using the 100% exact script with all other architectures with the only difference being the toolchain and architecture. I also found references to C:\cygwin\bin in the logs (note the backslashes instead of forward slashes) below which I'd imagine would cause the issue I am experiencing as I have no way to alter the -iprefix in the COLLECT_GCC_OPTIONS as I am not setting this parameter - seems the GCC compiler is injecting this in. I also realised that I needed to use the linux-gnu version of the toolchain and not the ELF version which I did, but got the same results. Cygwin DLL version (just in case). I called: cygcheck -p cygwin1.dll |grep "cygwin:" And it returned: cygwin-2.10.0-1 - cygwin: The UNIX emulation engine cygwin-2.8.2-1 - cygwin: The UNIX emulation engine cygwin-2.9.0-3 - cygwin: The UNIX emulation engine 7.2.1 Using built-in specs.

[ACTIVITY] - Landed D44928, we should pass the subtarget through to fixups and relaxation now. The only remaining use of the subtarget in the assembler backend is for writeNop(). Patches to fix that are upstream but I'm not hopeful that anyone will want to review them due to the cost/benefit. - Wrote up some thoughts on Maxim's idea to use pgo to optimize hot code for time, but cold code for size in an attempt to retain as much as performance as possible while reducing code-size. - Some investigation into the --pgo option of lnt. There seem to be some pre-requisites and some interactions that have made it difficult to get results: -- Needs compiler-rt, duh! But it didn't tell me until after I'd waited for everything to compile. -- Failed when I enabled perf and pgo, looks to be a configuration problem where profile-generate and profile-use are set simultaneously. Probably a cmake problem. - Some work on side-project to implement the tiny code model -- Have something working on small examples, much more testing needed. -- Need to decide what to do about TLS.
