The problem is that the computation of early call regions skips freeze nodes but scenarios involving procedures declared as actions of these freeze nodes are taken into account. As a consequence if a subprogram body, typically of an expression function, is placed just after a freeze node, its early call region depends on whether the construct just before the freeze node can be preelaborated or not; in other words, the legality of calls made from the actions of this freeze node to the subprogram depends on what happens ahead of the freeze node, which may be totally unrelated to the situation. This change disables the ABE diagnostics in this case, as is done in a few other similar cases leading to bogus errors too. gcc/ada/ * sem_elab.adb (Processing_In_State): Add Within_Freezing_Actions component. (Process_Conditional_ABE_Call): Compute its value. (Process_Conditional_ABE_Call_SPARK): For a call and a target in the main unit, do not emit any ABE diagnostics if the call occurs in a freezing actions context. |

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.
