gcc 3.2.2 release notes, third draft

[Joe Buck <jbuck at synopsys dot com>]

Here's a third draft of the GCC 3.2.2 release notes.  This is only a
draft, reflecting the state as of Gaby's third pre-release tarball.

Changes since last draft:

new ICE fixes: 7681, 9465
new C/optimizer fixes: 8639, 9492
new x86 fixes: 9506
Added RTEMS-specific and HP-PA-specific bug fixes
Combined trivial optimization fixes.

Please send me corrections or additions if you notice anything wrong or
missing.

-----------------------------------------

This document lists the problem reports (PRs) from GCC's bug tracking
system (GNATS) that are known to be fixed in the 3.2.2 release. This
list might not be complete (that is, it is possible that some PRs
that have been fixed are not listed here).

3.2.2 is a bug fix release only; there are no new features that were not
present in GCC 3.2.1.

To learn more about a particular PR, visit the link

	http://gcc.gnu.org/cgi-bin/gnatsweb.pl

and enter the PR number in the "View Problem Report" dialog box.  Then
click the "View" button.  It's not necessary to log in to view reports.

The sorting is slightly different from the GNATS categories, and some of
the titles have been changed to make them more clear.

First, internal compiler errors (ICEs).  These are multi-platform; some
processor-specific ICEs are listed in separate sections below.

5919	(c++) ICE when passing variable array to template function
7507	ICE with -O2 when address of called function is a complicated 
        expression
7622	ICE with nested inline functions if function's address is taken
7681	(fortran) ICE in compensate_edge, in reg-stack.c (also PR 9258)
8031	(c++) ICE in code comparing typeid's and casting from virtual base
8275	ICE in simplify_subreg
8332	(c++) builtin strlen/template interaction causes ICE
8372	(c++) ICE on explicit call of destructor
8439	(c, not c++) empty struct causes ICE
8442    (c++) ICE with nested template classes
8518	ICE when compiling mplayer ("extern inline" issue)
8615	(c++) ICE with out-of-range character constant template argument
8663	(c++) ICE in cp_expr_size, at cp-lang.c:307
8799	(c++) ICE: error reporting routines re-entered
9328    (c++) ICE with typeof(X) for overloaded X
9465	(preprocessor) cpp -traditional ICE on null bytes

9076	Call Frame Instructions are not handled correctly during
        unwind operation
9151	std::setprecision limited to 16 digits when outputting a double
	to a stream
9168	codecvt<char, char, mbstate_t> overwrites output buffers

C and optimizer bugs

8032	GCC incorrectly initializes static structs that have flexible arrays
8639	simple arithmetic expression broken
8794	optimization improperly eliminates certain expressions

	(found on i386, bug present for all platforms)
9492	structure copy clobbers subsequent stores to structure

Objective-C bugs

9267	Objective-C parser won't build with newer bison versions (e.g. 1.875)
