From: dan@...

IMHO either something call __multi3 and doesn't link to libgcc or gcc emits call to __multi3 and it's not implemented in libgcc. Would be useful to see /tmp/_ruby_mjit_p20163u1.c source and the command line used to compile/link it. ---------------------------------------- Bug #15522: TestJIT#test_compile_insn_local fails on aarch64 RHEL7 https://bugs.ruby-lang.org/issues/15522#change-76208 * 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. -- https://bugs.ruby-lang.org/ Unsubscribe:
