Under NPM, the asan-globals-md analysis is required but cannot be run
within the asan function pass due to module analyses not being able to
run from a function pass. So this pins all tests using "-asan" to the
legacy PM and adds a corresponding RUN line with
-passes='require<asan-globals-md>,function(asan)'.
Now all tests in Instrumentation/AddressSanitizer pass when
-enable-new-pm is by default on.
Tests were automatically converted using the following python script and
failures were manually fixed up.
import sys
for i in sys.argv:
with open(i, 'r') as f:
s = f.read()
with open(i, 'w') as f:
for l in s.splitlines():
if "RUN:" in l and ' -asan -asan-module ' in l and '\\' not in l:
f.write(l.replace(' -asan -asan-module ', ' -asan -asan-module -enable-new-pm=0 '))
f.write('\n')
f.write(l.replace(' -asan -asan-module ', " -passes='require<asan-globals-md>,function(asan),module(asan-module)' "))
f.write('\n')
elif "RUN:" in l and ' -asan ' in l and '\\' not in l:
f.write(l.replace(' -asan ', ' -asan -enable-new-pm=0 '))
f.write('\n')
f.write(l.replace(' -asan ', " -passes='require<asan-globals-md>,function(asan)' "))
f.write('\n')
else:
f.write(l)
f.write('\n')
