Hi all,the following is motivated by GCC testsuite – which uses 'dg-set-target-env-var' to set per-test-case environment variables (used with the address-sanitizer (ASAN) and in the testsuite for OpenMP/OpenACC (libgomp)). [The latter also uses 'setenv' for offloading for all runs per offloading target.] – GCC uses 'setenv' for this purpose, which works well if host = target (= ![is_remote…]) – but when doing remote execution, it does not work.The question is how to best support setting the environment variable remote. I could imagine to either pass environment variables alongside when running remote_spawn/remote_exec or to have a remove_setenv.Thoughts?
As an interim measure, could you simply prepend the needed environment variables to the remote command and/or use env(1)?
