Subject: Replaced POP() with STACKADJ(-1) on lines where the result wasn't used.
X-Git-Tag: v2.3c1~2459
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8bb90a59a641979385f063249143a05a6198725e;p=thirdparty%2FPython%2Fcpython.git

Replaced POP() with STACKADJ(-1) on lines where the result wasn't used.

The two are semantically equivalent, but the first triggered a compiler
warning about an unused variable.  Note, the preceding steps had already
accessed and decreffed the variable so the reference counts were fine.
