If a jump always falls through but that cannot be optimised away, like is the case with the PowerPC bdnz insn if its jump target is the same as the fallthrough, sched gets confused if it schedules some instructions from before that jump instruction to behind it: it splits the fallthrough branch, but the jump target isn't updated, and things fall apart as in the PR. This patch fixes it. The second patch fragment makes -fsched-verbose=N work for N>=4; the currently scheduled fragment can now contain a label. Everything else seems to work fine with that. PR target/72749 * cfgrtl.c (rtl_split_edge): Also patch jump insns that jump to the fallthrough. * haifa-sched.c (dump_insn_stream): Don't crash if there is a label in the currently scheduled RTL fragment.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
