Subject: doc: Avoid using stdout in Makefile rule to generate .spv files.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e2b97c605195dfc4d899caeb4002aea6a1e26471;p=pspp

doc: Avoid using stdout in Makefile rule to generate .spv files.

When pspp writes anything to stdout, also writing the .spv file to stdout
causes confusing corruption.  This avoids the problem.
