ASan port for Myriad RTEMS
Hi Walter, I've done a first quick scan. Overall looks reasonable, but I'd like to try reducing the number of newly introduced platform-specific ifs. Vitaly, please also take a look (once my initial comments are addressed). One outstanding issue is your problem with initialization vs checking, which requires you to insert so many ifs. Is there any chance you can avoid this? If you

ASan port for Myriad RTEMS
Hey, I work on fuchsia symbolizer stuff. I don't know if you guys already have an external symbolizer but I'm working on making one right now and I plan on making one backed by LLVM that can be run host-side or target-side. I'd like to contribute that back to llvm ideally. What do you guys have so far? I have a prototype in golang that just spins up an instance of llvm-symbolizer

ASan port for Myriad RTEMS
Hi Jake. Thanks for the info. Where can I keep up to date on the symbolizer status? Our symbolizer is provided by the Myriad vendor and integrated into its host test environment. It doesn't do much: just look for PC string patterns and symbolize them using addr2line. Thanks, Walter On Fri, May 4, 2018 at 5:36 PM Jake Ehrlich <jakehehrlich at google.com> wrote: > Hey, > I

ASan port for Myriad RTEMS
Hi Kostya. Thanks for the quick feedback. I will work on addressing your comments. In regard to initialization checks, I can eliminate most of them by initializing the shadow memory very early, but I still need to do something in two places, __asan_handle_no_return and GetFakeStackFast. Would it be ok to have guards for those two places only? Walter On Fri, May 4, 2018 at 6:10 PM Kostya

ASan port for Myriad RTEMS
I have ported ASan in LLVM to Myriad RTEMS, and I would like to upstream the port. Below is the design doc. Feedback welcome. https://docs.google.com/document/d/1oxmk0xUojybDaQDAuTEVpHVMi5xQX74cJPyMJbaSaRM The port is expected to work with modified versions of RTEMS and newlib. I have a git repo with changes to those projects, that I can make available if there is interest. Here is the patch

On RAM... You chose the 32-byte shadow granularity to reduce the RAM overhead, but I am afraid this will actually increase it due to extra alignment requirements, especially if an average allocation on your typical application is small. The pointers are 32-bit, right? Given how RAM-constrained your environment is, maybe you should consider something more like HWASAN instead of ASAN.

Good point. I will run our test suite with 8-byte shadow

ASan port for Myriad RTEMS
I ran our test suite with grain of 8 and 32, and more tests were able to avoid running out of memory with grain of 32 than 8. The ones that run out of memory on 8 but not 32 all failed trying to allocate a large region from the heap (350M). I haven't had any tests that run out of memory for other reasons. Given that, I will check in the current selected granularity of 32. I will try grain

[LLVMdev] LatticeMico32 (LM32) backend
Hi, Would anyone be interested in developing a LatticeMico32 backend in LLVM? LatticeMico32 [1] is an open source microprocessor core designed by Lattice Semiconductor and typically used in FPGAs. It is comparable to the Microblaze processor that you already support. It is already supported by GNU Binutils and GCC (4.5+). It is used by the Milkymist [2] and RTEMS [3] projects. The Milkymist
