Subject: bpo-42825: Enable /OPT:REF (GH-24098)
X-Git-Tag: v3.10.0a6~56
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b4af629f4d4868ef74ee298d66259fae78c7fd89;p=thirdparty%2FPython%2Fcpython.git

bpo-42825: Enable /OPT:REF (GH-24098)

We explicitly disable /OPT:ICF as some manual optimisations depend on some functions still having distinct pointers (such as wrap_binary_func and wrap_binary_func_l).
