gcc/ * cfgexpand.c (expand_asm_stmt): Output asm goto with outputs too. Place insns after asm goto on edges. * doc/extend.texi: Reflect the changes in asm goto documentation. * gimple.c (gimple_build_asm_1): Remove an assert checking output absence for asm goto. * gimple.h (gimple_asm_label_op, gimple_asm_set_label_op): Take possible asm goto outputs into account. * ira.c (ira): Remove critical edges for potential asm goto output reloads. (ira_nullify_asm_goto): New function. * ira.h (ira_nullify_asm_goto): New prototype. * lra-assigns.c (lra_split_hard_reg_for): Use ira_nullify_asm_goto. Check that splitting is done inside a basic block. * lra-constraints.c (curr_insn_transform): Permit output reloads for any jump insn. * lra-spills.c (lra_final_code_change): Remove USEs added in ira for asm gotos. * lra.c (lra_process_new_insns): Place output reload insns after jumps in the beginning of destination BBs. * reload.c (find_reloads): Report error for asm gotos with outputs. Modify them to keep CFG consistency to avoid crashes. * tree-into-ssa.c (rewrite_stmt): Don't put debug stmt after asm goto. gcc/c/ * c-parser.c (c_parser_asm_statement): Parse outputs for asm goto too. * c-typeck.c (build_asm_expr): Remove an assert checking output absence for asm goto. gcc/cp * parser.c (cp_parser_asm_definition): Parse outputs for asm goto too. gcc/testsuite/ * c-c++-common/asmgoto-2.c: Permit output in asm goto. * gcc.c-torture/compile/asmgoto-2.c: New. * gcc.c-torture/compile/asmgoto-3.c: New. * gcc.c-torture/compile/asmgoto-4.c: New. * gcc.c-torture/compile/asmgoto-5.c: New.
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.
