* gcc.dg/tree-ssa/loop-36.c: Reduce amount of iterations to 2 so unrolling still happens. * gcc.dg/ipa/ipacost-1.c: Prevent inlining * gcc.dg/ipa/ipacost-2.c: Likewise. * gcc.dg/vect/slp-3.c: Loop is no longer unrolled. * tree-inline.c (estimate_operator_cost): Add operands; when division happens by constant, it is cheap. (estimate_num_insns): Loads and stores are not having cost of 0; EH magic stuff is cheap; when computing runtime cost of switch, use log2 base of amount of its cases; builtin_expect has cost of 0; compute cost for moving return value of call. (init_inline_once): Initialize time_based flags. * tree-inline.h (eni_weights_d): Add time_based flag. From-SVN: r147436
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
