Subject: Disable peg generator tests when building with PGO (GH-23141)
X-Git-Tag: v3.10.0a3~266
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=100964e0310d3a2040d0db976f7984d0507b2dbd;p=thirdparty%2FPython%2Fcpython.git

Disable peg generator tests when building with PGO (GH-23141)

Otherwise, when running the testsuite, test_peg_generator tries to compile C
code using the optimized flags and fails because it cannot find the profile
data.
