2003-07-10 Kazu Hirata <kazu@cs.umass.edu> PR c/11449 * fold-const.c (sign_bit_p): Return EXP if VAL is the sign bit of HOST_WIDE_INT. (fold_single_bit_test): If sign_bit_p() fails, assume that the bit being tested is not a sign bit. 2003-07-04 Jeff Law <law@redhat.com> PR c/11428 * expr.c (do_store_flag): Pass in the correct result type when calling fold_single_bit_test. * fold-const.c (fold_single_bit_test): Use result_type for the result when folding a sign bit test. 2003-07-02 Jeff Law <law@redhat.com> * expr.c (do_store_flag): Remove special case folding for single bit tests. Instead call back into the commonized folder routine. * fold-const.c (fold_single_bit_test): New function, mostly extracted from do_store_flag, with an additional case extracted from fold. (fold): Call fold_single_bit_test appropriately. * tree.h (fold_single_bit_test): Prototype. |

$NetBSD: README,v 1.5 2003/12/04 23:32:37 keihan Exp $ Organization of Sources: This directory hierarchy is using a new organization that separates the GNU sources from the BSD-style infrastructure used to build the GNU sources. The GNU sources are kept in the standard GNU source tree layout under: dist/* The build infrastructure uses the normal BSD way under: lib/* usr.bin/* The makefiles in the above hierarchy will "reach over" into the GNU sources (src/gnu/dist) for everything they need. Maintenance Strategy: The sources under src/gnu/dist are generally a combination of some published distribution plus changes that we submit to the maintainers and that are not yet published by them. There are a few files that are never expected to be submitted to the FSF, (i.e. BSD-style makefiles and such) and those generally should stay in src/gnu/lib or src/gnu/usr.bin (the BSD build areas). Make sure all changes made to the GNU sources are submitted to the appropriate maintainer, but only after coordinating with the NetBSD maintainers by sending your proposed submission to the <tech-toolchain@NetBSD.org> mailing list. Only send the changes to the third-party maintainers after consensus has been reached.
