Use FOR_BB_INSNS_SAFE instead of for loop. * cse.c (cse_extended_basic_block): Likewise. * postreload.c (reload_cse_regs_1): New variable next. Make sure that the for loop does not invoke NEXT_INSN on a deleted insn. * function.c (instantiate_virtual_regs): Likewise. * lower-subreg.c (remove_retval_note): Likewise. (decompose_multiword_subregs): Use FOR_BB_INSNS_SAFE instead of FOR_BB_INSNS. * emit-rtl.c (remove_insn): Set NEXT_INSN and PREV_INSN to NULL on a deleted insn. * cfgrtl.c (delete_insn): Set JUMP_LABEL to NULL on a deleted insn, if it's a jump. (try_redirect_by_replacing_jump): New variable jump_p. Call tablejump_p before delete_insn_chain. * reload1.c (reload): New variable next. Make sure that the for loop does not invoke NEXT_INSN on a deleted insn. (fixup_eh_region_note): Make the loop terminate if i becomes NULL. (delete_output_reload): New variable prev.

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.
