From f4df0edf3ea39a686abc5753c2d98d61082d02a7 Mon Sep 17 00:00:00 2001 From: Vedant Kumar Date: Wed, 26 Oct 2016 22:07:39 +0000 Subject: [PATCH] [utils] Add a '--unified-report' option to the code coverage prep script In --unified-report mode, a single coverage report is prepared for all specified binaries and written to *report_dir*. This mode is compatible with all existing script options, including the --restrict mode which is used to limit coverage reporting to certain files or directories. This should not break any existing users of the script. llvm-svn: 285249 --- llvm/utils/prepare-code-coverage-artifact.py | 41 ++++++++++++++------ 1 file changed, 29 insertions(+), 12 deletions(-) diff --git a/llvm/utils/prepare-code-coverage-artifact.py b/llvm/utils/prepare-code-coverage-artifact.py index 05a774cbcce9..726375e899cd 100644 --- a/llvm/utils/prepare-code-coverage-artifact.py +++ b/llvm/utils/prepare-code-coverage-artifact.py @@ -31,26 +31,37 @@ def merge_raw_profiles(host_llvm_profdata, profile_data_dir, preserve_profiles): print('Done!') return profdata_path -def prepare_html_report(host_llvm_cov, profile, report_dir, binary, +def prepare_html_report(host_llvm_cov, profile, report_dir, binaries, restricted_dirs): - print(':: Preparing html report for {0}...'.format(binary), end='') + print(':: Preparing html report for {0}...'.format(binaries), end='') sys.stdout.flush() - binary_report_dir = os.path.join(report_dir, os.path.basename(binary)) - invocation = [host_llvm_cov, 'show', binary, '-format', 'html', - '-instr-profile', profile, '-o', binary_report_dir, + objects = [] + for i, binary in enumerate(binaries): + if i == 0: + objects.append(binary) + else: + objects.extend(('-object', binary)) + invocation = [host_llvm_cov, 'show'] + objects + ['-format', 'html', + '-instr-profile', profile, '-o', report_dir, '-show-line-counts-or-regions', '-Xdemangler', 'c++filt', '-Xdemangler', '-n'] + restricted_dirs subprocess.check_call(invocation) - with open(os.path.join(binary_report_dir, 'summary.txt'), 'wb') as Summary: - subprocess.check_call([host_llvm_cov, 'report', binary, - '-instr-profile', profile], stdout=Summary) + with open(os.path.join(report_dir, 'summary.txt'), 'wb') as Summary: + subprocess.check_call([host_llvm_cov, 'report'] + objects + + ['-instr-profile', profile], stdout=Summary) print('Done!') def prepare_html_reports(host_llvm_cov, profdata_path, report_dir, binaries, - restricted_dirs): - for binary in binaries: - prepare_html_report(host_llvm_cov, profdata_path, report_dir, binary, + unified_report, restricted_dirs): + if unified_report: + prepare_html_report(host_llvm_cov, profdata_path, report_dir, binaries, restricted_dirs) + else: + for binary in binaries: + binary_report_dir = os.path.join(report_dir, + os.path.basename(binary)) + prepare_html_report(host_llvm_cov, profdata_path, binary_report_dir, + [binary], restricted_dirs) if __name__ == '__main__': parser = argparse.ArgumentParser(description=__doc__) @@ -69,6 +80,8 @@ if __name__ == '__main__': help='Do not delete raw profiles', action='store_true') parser.add_argument('--use-existing-profdata', help='Specify an existing indexed profile to use') + parser.add_argument('--unified-report', action='store_true', + help='Emit a unified report for all binaries') parser.add_argument('--restrict', metavar='R', type=str, nargs='*', default=[], help='Restrict the reporting to the given source paths') @@ -85,6 +98,10 @@ if __name__ == '__main__': args.profile_data_dir, args.preserve_profiles) + if not len(args.binaries): + print('No binaries specified, no work to do!') + exit(1) + if not args.only_merge: prepare_html_reports(args.host_llvm_cov, profdata_path, args.report_dir, - args.binaries, args.restrict) + args.binaries, args.unified_report, args.restrict)
