(unshare_variable): New function. (vars_copy_1): Increase refcount instead of copying the variable. (variable_union): Share the variables where possible, unshare the variables if needed. (variable_different_p): Return false if var1 and var2 are the same structure. (variable_was_changed): Init the refcount of new variable. (set_frame_base_location): Unshare variable if needed. (set_variable_part): Init the refcount of new variable. Unshare the variables if needed. (delete_variable_part): Unshare the variables if needed. (emit_notes_for_differences_1): Init the refcount of new variable. (vt_add_function_parameters): Do not add function parameters to IN set of ENTRY_BLOCK_PTR because it is unused anyway. (vt_initialize): Do not add frame_base_decl to IN set of ENTRY_BLOCK_PTR because it is unused anyway. From-SVN: r79307 |

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.
