Hi all, I noticed that interleaved IR dump causes some tests to fail, which would otherwise pass. I can name a few tests, but there are more: - alias_alloc.lua - jit_flush.lua - unordered_jit.lua - ffi_nosink.lua Regards, Stefan

Re: Recent merged patches break test cases

by Zhongwei Yao

Hi, I just check: tnew and tdup pass after changing variable name ("table"). hload_num hstore_pri hstore_str hstore_num still fail.

VM error while trying to dump emitted machine code in tnew.lua

by Dikshit, Abhishek

Hi All I am getting following error when I try to dump the machine code for test/tnew.lua $ ./luajit -jon -jdump=m ../test/tnew.lua ---- TRACE 1 start tnew.lua:1 ---- TRACE 1 mcode 316 VM handler failed: ./jit/dis_arm.lua:439: attempt to call upvalue 'concat' (a nil value) $ ./luajit -jon -jdump=m ../test/tnew.lua ---- TRACE 1 start tnew.lua:1 ---- TRACE 1 mcode 384 VM handler failed: ./jit/dis_arm64.lua:755: attempt to call upvalue 'concat' (a nil value) The error is seen on ARM64 and ARM32 but not on x64. I am having tough time to debug the asm_tbar function for failure of test_tnew. Any suggestion is welcome. Abhishek Dikshit

asm_tbar, asm_cnew and emit_isk13 changes for review

by Dikshit, Abhishek

Hi All I am new to both luajit and ARM. I have made the changes for the functions asm_tbar, asm_cnew and emit_isk13 for arm64 based on my limited understanding. I have attached the diffs. Please review the diffs and share any suggestions you have. The changes are mostly based on arm32 code for corresponding functions. The diffs are corresponding to test case in the attached email. Thanks Abhishek Dikshit

CI for LuaJIT

by Zheng Xu

Hi all, There are more and more tests added to the project. And we are fixing issues in the common IRs and even common codes. I think it is time to set up CI for the project to help people to identify issues early. We have in house CI set up for the project which will do test for arm32, arm64, x86 and x86_64, but unfortunately it can not be accessed from public domain. I will try to get the approval from the managers to copy the scripts to Linaro CI if possible. I will get back to you once I got the approval or be rejected. Hi Alan & Fathi, I saw there are some aarch64 and x86 machines available on ci.linaro.org. Can we share use some of them for LuaJIT CI? If I am able to copy the scripts to Linaro CI, the basic requirement for the infrastructure would be : - 1 aarch64 machine with ubuntu installed - 1 x86_64 machine with ubuntu installed - 1 gerrit project to host the CI scripts - It is a GitHub project, so we might need some related plugins installed in the Jenkins system. - Might need help from your team to run a script to setup the host environment or setup the host manually. (docker, makefile and some other dependencies) - We do not have many tests so far, so the job won't be too large. It should be able to be finished within 15 minutes. Can these requirement be satisfied? Regards, Zheng

asm_head_side_base

by Stefan Pejic

Hi all, I submitted another small pull request that fixes IR_ADD/SUB. It allows them to work with 64-bit values. The issue can be reproduces with vload.lua test. The next thing that is a blocker for quite a lot of tests is asm_head_side_base. Is anyone working on that? If not, I will look into it. Thanks, Stefan
