[ASan] Use dynamic shadow on 32-bit iOS and simulators The VM layout on iOS is not stable between releases. On 64-bit iOS and its derivatives we use a dynamic shadow offset that enables ASan to search for a valid location for the shadow heap on process launch rather than hardcode it. This commit extends that approach for 32-bit iOS plus derivatives and their simulators. rdar://50645192 rdar://51200372 rdar://51767702 Reviewed By: delcypher Differential Revision: https://reviews.llvm.org/D63586 llvm-svn: 364105

[NewPM][ASan] Make ASan tests work under NPM 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') See https://bugs.llvm.org/show_bug.cgi?id=46611.
