I build an aarch64 cross-compile toolchain by myself. And, I find out my gcc aarch64 corss-compile toolchain have the same bug mentioned in PR target/63293 . https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63293 Because I want to use the current gcc source to build an another arm target cross-compile toolchain. My question will be: Does the arm target cross-compile toolchain will also have similar bug ? or The code generation logic between aarch64 and arm target is very different . I should not worry too much ? BR, che-yang
