- Add comment on patch-lib_isnan.c (from cvs log)
(upstream)
- Update devel/bison 3.0.2 to 3.0.3
Thanks obache and wiz for review.
---------------------------------
* Noteworthy changes in release 3.0.3 (2015-01-15) [stable]
** Bug fixes
*** C++ with Variants (lalr1.cc)
Problems with %destructor and '%define parse.assert' have been fixed.
*** Named %union support (yacc.c, glr.c)
Bison 3.0 introduced a regression on named %union such as
%union foo { int ival; };
The possibility to use a name was introduced "for Yacc compatibility".
It is however not required by POSIX Yacc, and its usefulness is not clear.
*** %define api.value.type union with %defines (yacc.c, glr.c)
The C parsers were broken when %defines was used together with "%define
api.value.type union".
*** Redeclarations are reported in proper order
On
%token FOO "foo"
%printer {} "foo"
%printer {} FOO
bison used to report:
/tmp/foo.yy:2.10-11: error: %printer redeclaration for FOO
%printer {} "foo"
^^
/tmp/foo.yy:3.10-11: previous declaration
%printer {} FOO
^^
Now, the "previous" declaration is always the first one.
** Documentation
Bison now installs various files in its docdir (which defaults to
'/usr/local/share/doc/bison'), including the three fully blown examples
extracted from the documentation:
- rpcalc
Reverse polish calculator, a simple introductory example.
- mfcalc
Multi-function Calc, a calculator with memory and functions and located
error messages.
- calc++
a calculator in C++ using variant support and token constructors.
