From: Clifford Wolf Date: Sun, 6 Jan 2013 12:50:30 +0000 (+0100) Subject: Improvements in command shell X-Git-Tag: yosys-0.2.0~799 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ae731369ddb8838302b5d9a3fa32689c44ab7934;p=yosys.git Improvements in command shell - Added 'shell' command (run interactive shell from synth script) - Added support for ; as cmd seperator as in "proc; opt" - Fixed c++ static initialization order problem with pass register --- diff --git a/kernel/driver.cc b/kernel/driver.cc index c49bf6575..ae1796757 100644 --- a/kernel/driver.cc +++ b/kernel/driver.cc @@ -140,6 +140,40 @@ static const char *create_prompt(RTLIL::Design *design) return buffer;
