When the DWARF back-end generates DW_OP_neg operations in DWARF procedures, we get an ICE because of inconsistent stack usage computation for the embedding expression. This is because resolve_args_picking_1 thinks DW_OP_neg is a binary operation (pops 2 stack slots, pushes 1) whereas it really is an unary one (one pop, one push). This change fixes resolve_args_picking_1 and adds a regression testcase (which crashes with the current trunk). Bootstrapped and regtested without regression on x86_64-linux. gcc/ * dwarf2out.c (resolve_args_picking_1): Consider DW_OP_neg as an unary operation, not a binary one. gcc/testsuite/ * gnat.dg/debug6.adb, gnat.dg/debug6_pkg.ads: 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.
