This removes gimple_debug_begin_stmts without block info which remain after a gimple block originating from an inline function is unused. The line numbers from these stmts are from the inline function, but since the inline function is completely optimized away, there will be no DW_TAG_inlined_subroutine so the debugger has no callstack available at this point, and therefore those line table entries are not helpful to the user. 2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de> * cfgexpand.c (expand_gimple_basic_block): Remove special handling of debug_inline_entries without block info. * tree-inline.c (remap_gimple_stmt): Drop debug_nonbind_markers when the call statement has no block info. (copy_debug_stmt): Remove debug_nonbind_markers when inlining and the block info is mapped to NULL. * tree-ssa-live.c (clear_unused_block_pointer): Remove debug_nonbind_markers originating from removed inline functions. |

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.
