If you leave those flags in, MJIT doesn't work. `--jit-verbose=2` output on OpenBSD/amd64 with gcc forced as the compiler shows: ``` /usr/bin/ld: error: can't create dynamic relocation R_X86_64_PC32 against symbol: __guard_local in readonly segment; recompile object files with -fPIC >>> defined in /tmp/_ruby_mjit_p43488u28.o >>> referenced by _ruby_mjit_p43488u28.c >>> /tmp/_ruby_mjit_p43488u28.o:(_mjit28) collect2: ld returned 1 exit status link_o_to_so: link error: 1 ``` or on OpenBSD/powerpc (where GCC is the default system compiler): ``` Starting process: cc cc -shared -Wfatal-errors -fPIC -shared -w -pipe -O3 -o /tmp/_ruby_mjit_p40346u0.so /tmp/_ruby_mjit_p40346u0.o -L/usr/local/lib -nostartfiles -nodefaultlibs -nostdlib ruby26:/tmp/_ruby_mjit_p40346u0.so: undefined symbol '__guard_local' MJIT warning: failure in loading code from '/tmp/_ruby_mjit_p40346u0.so': Cannot load specified object ``` The attached patch fixes the issue. ---Files-------------------------------- mjit_worker.diff (1.21 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
