While ignored ghost code is not compiled into the executable, it may lead to compilation errors when it makes use of language features requiring runtime support that is not available in the available runtime library. These errors are spurious, as the executable will never call in these runtime units. This patch deactivates the expansion of code inside ignored ghost bodies of subprograms and packages, so that this code is still checked for possible semantic errors, but it does not force the presence of useless runtime units. There is no impact on the executable produced. 2018-12-11 Yannick Moy <moy@adacore.com> gcc/ada/ * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Deactivate expansion in ignored ghost subprogram body. * sem_ch7.adb (Analyze_Package_Body_Helper): Deactivate expansion in ignored ghost package body. gcc/testsuite/ * gnat.dg/ghost4.adb: New testcase.

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.
