Hi Alexandre: We've added a new configure option to allow you to override that without changing source code.
For example: --with-multilib-generator="rv32i-ilp32--c;rv32im-ilp32--c;rv32iac-ilp32--;rv32imac-ilp32--;rv32imafc-ilp32f-rv32imafdc-;rv64im-lp64--;rv64imc-lp64--;rv64imfc-lp64f--;rv64imac-lp64--;rv64imafdc-lp64d--" Doc: https://gcc.gnu.org/install/configure.html GCC Changes: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=c1e6691245ca2f1f329549f323f67afe32bcb97a On Tue, Feb 23, 2021 at 4:01 PM Alexandre Oliva <ol...@adacore.com> wrote: > > > We've had customer demand for these multilibs.
