In the 'RTL SSA Access Lists' subsection of GCC's documentation, an example of code with an 'if'...'else' structure is given. The given list of the full list of accesses is said to include "use of the ebb4's R phi definition of R by B". That cannot be true because B is in the first substatement of the 'if' statement, whereas ebb4 is the second substatement. First and second substatements are mutually exclusive: there is no path to B that goes through the degenerate phi node of ebb4. It looks as though D was intended, not B. gcc/ChangeLog: * doc/rtl.texi: Fix example of the SSA form.
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.
