This changes the compiler to build in place almost all objects that need finalization and are initialized with the result of a function call, thus saving a pair of Adjust/Finalize calls for the anonymous return object. gcc/ada/ * exp_ch3.adb (Expand_N_Object_Declaration): Don't adjust the object if the expression is a function call. <Rewrite_As_Renaming>: Return true if the object needs finalization and is initialized with the result of a function call returned on the secondary stack. * exp_ch6.adb (Expand_Ctrl_Function_Call): Add Use_Sec_Stack boolean parameter. Early return if the parent is an object declaration and Use_Sec_Stack is false. (Expand_Call_Helper): Adjust call to Expand_Ctrl_Function_Call. * exp_ch7.adb (Find_Last_Init): Be prepared for initialization still present in the object declaration. * sem_ch3.adb (Analyze_Object_Declaration): Call the predicates Needs_Secondary_Stack and Needs_Finalization to guard the renaming optimization. |

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.
