dummy-checksum.c: New.
2005-05-18 Geoffrey Keating <geoffk@apple.com> * dummy-checksum.c: New. * genchecksum.c: New. * c.opt (print_pch_checksum): New flag. * c-pch.c (struct c_pch_validity): Make much shorter. (no_checksum): New. (host_machine): Remove. (target_machine): Remove. (get_ident): Change PCH version number. (pch_init): When -fverbose-asm, print out the compiler fingerprint. Don't put triplets or version string in PCH validity data. Do put the compiler checksum in the validity data. (c_common_valid_pch): Don't check triplets or version string. Do check checksum. (c_common_print_pch_checksum): New. * c-opts.c (c_common_handle_option): Add OPT_print_pch_checksum. Print fingerprint with -v. * c-common.h (c_common_print_pch_checksum): New. (executable_checksum): New. * Makefile.in (STAGEMOVESTUFF): Add cc1*-dummy, *-checksum.c. (cc1-dummy): New rule. (cc1-checksum.c): New rule. (cc1-checksum.o): New rule. (cc1): Add checksum support. (build/genchecksum): New. (build/genchecksum.o): New. (dummy-checksum.o): New. (genobjnames): Add genchecksum.o. (mostlyclean): Remove *-checksum.c. (gnucompare): Add libgcc to list of directories checked. Make comparison problems in libgcc/ and with checksum files only be warnings. * doc/invoke.texi (Precompiled Headers): Remove caution. Document that it must be the exact same binary. Add a few known-safe flags to the list. In cp/: 2005-05-18 Geoffrey Keating <geoffk@apple.com> * Make-lang.in (cc1plus-dummy): New. (cc1plus-checksum.c): New. (cc1plus-checksum.o): New. (cc1plus): Add cc1plus-checksum.o. In objc/: 2005-05-18 Geoffrey Keating <geoffk@apple.com> * Make-lang.in (cc1obj-dummy): New. (cc1obj-checksum.c): New. (cc1obj-checksum.o): New. (cc1obj): Add cc1obj-checksum.o. In objcp/: 2005-05-18 Geoffrey Keating <geoffk@apple.com> * Make-lang.in (cc1objplus-dummy): New.
