I'll change that later. > This should be the C code (although generated on my x86_64, because I don't have aarch64 readily available). How did you get the output in the ticket description? If possible, I want you to upload rb_mjit_min_header-2.6.0.h under install directory and the exact /tmp/_ruby_mjit_p20163u1.c whose so can't be loaded. ---------------------------------------- Bug #15522: TestJIT#test_compile_insn_local fails on aarch64 RHEL7 https://bugs.ruby-lang.org/issues/15522#change-76213 * Author: vo.x (Vit Ondruch) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.6.0p0 (2018-12-25 revision 66547) [aarch64-linux] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- Trying to build Ruby 2.6 on RHEL7, I observe the following test failure on RHEL7, but just on aarch64. The other platforms pass just fine: ~~~ 1) Failure: TestJIT#test_compile_insn_local [/builddir/build/BUILD/ruby-2.6.0/test/ruby/test_jit.rb:64]: Expected 3 times of JIT success, but succeeded 2 times. script: ``` def foo a = 0 [1, 2].each do |i| a += i [3, 4].each do |j| a *= j end end a end print foo ``` stderr: ``` JIT success (276.6ms): foo@-e:2 -> /tmp/_ruby_mjit_p20163u0.c JIT success (347.3ms): block in foo@-e:4 -> /tmp/_ruby_mjit_p20163u1.c MJIT warning: failure in loading code from '/tmp/_ruby_mjit_p20163u2.so': /tmp/_ruby_mjit_p20163u2.so: undefined symbol: __multi3 Successful MJIT finish ``` . <3> expected but was <2>. ~~~ I suspect this must be some combination of architecture/compiler (gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-16)), because I don't observe similar issues on Fedora. ---Files-------------------------------- _ruby_mjit_p207u2.c (3.48 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
