Subject: RTLIL: use {get,set}_string_attribute in {get,set}_strpool_attribute.
X-Git-Tag: working-ls180~490^2~3
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e558905598617c901607a93e902d57f9a88f6da0;p=yosys.git

RTLIL: use {get,set}_string_attribute in {get,set}_strpool_attribute.

The only difference in behavior is that this removes the attribute
when the pool becomes empty.
