After 2010-10-07 Andi Kleen <ak@linux.intel.com> * Makefile.in (MOSTLYCLEANFILES): Remove cc1*dummy, add checksum-options. (checksum-options): Add. (cc1-dummy): Remove. (cc1-checksum): Change to run checksum over object files and options only. * dummy-checksum.c: Remove. * genchecksum.c: Update copyright. (usage): Allow multiple arguments. (BLOCKSIZE): Add. (dosum): Change for incremental checksum. Remove C output. (main): Iterate over all argument files. Add C output. there are no longer binaries with dummy-checksum.c we guard against using. Bootstrap running on x86_64-unknown-linux-gnu. Richard. 2019-02-22 Richard Biener <rguenther@suse.de> c-family/ * c-pch.c (no_checksum): Remove. (pch_init): Remove assertion that executable_checksum is not all zero. (c_common_valid_pch): Likewise.
