This is the CHANGES file for cv2pdb, a
converter of DMD CodeView/DWARF debug information to PDB files
Copyright (c) 2009-2012 by Rainer Schuetze, All Rights Reserved
Version history
---------------
2009-05-08 Version 0.1
* initial release
2009-05-16 Version 0.2
* replace .debug section in executable rather than rename it. (only works
if it is the last section).
* support for field type LF_VFUNCTAB and symbol type S_CONSTANT used by DMC.
* added stringview to autoexp.dat for full length text display.
2009-06-04 Version 0.3
* static members' debug info was not correctly converted, causing debugger confusion
* now works on executables compiled by DMC
- added command line switch -C to disable some D feature and
to remove function name from local variables
- added support for type LF_BITFIELD.
* added fields __viewhelper to classes string and object
* new addin dviewhelper.dll to display correctly terminated strings
and derived object type
2009-06-05 Version 0.4
* fixed crash when long is used as index or element type of dynamic or
associative arrays
2009-06-06 Version 0.5
* fixed error in __viewhelper field of string type, that could screw up type info
* added support for wstring and dstring
* fixed problems with debug info inside library by combining debug info of different modules
into a single pseudo-module
* now also replaces '.' by '@' in enumerator types for more consistent debug info
2009-06-07 Version 0.6
* removed LF_DERIVED info from debug info, as it is inconsistent in DMD generated info
with more than 4096 type entries
2009-06-08 Version 0.7
* corrected number of field entries in classes or struct, because DMD miscounts private members
2009-06-11 Version 0.8
* tweaked visualizer macros to detect uninitialized associative arrays and to limit expansion
to arrays with less than 1024 entries
* renamed data pointer member of dynamic arrays to "ptr" to be consistent with the array property
in D.
2009-06-19 Version 0.9
* fixed line number info at the end of a segment or when switching to another file
because of inline expansion
* fixed line numbers > 32767 and sections with 0 line number entries
2009-08-12 Version 0.10
* better support for DMC:
- entries LF_FRIENDFCN removed
- entries LF_FRIENDCLS, LF_VBCLASS and LF_IVBCLASS converted
thanks to Andrew.
* derived-classes info in class entry now cleared to be consistent with removal of LF_DERIVED
2009-12-29 Version 0.11
* basic types now show with their D names, not as C types
* "enum" prefix removed from type names of enumerator types
* added type information for complex data types
* dmd-patch needed for long/ulong support (http://d.puremagic.com/issues/show_bug.cgi?id=3373)
* experimental hack to add lexical scope to local variables (dmd patch in
http://d.puremagic.com/issues/show_bug.cgi?id=3657 needed)
2010-04-13 Version 0.12
* added patch to convert binaries produced by Metroworks CodeWarrior
* names of local function are now demangled
* dmd 2.041 fixes long/ulong support (patch http://d.puremagic.com/issues/show_bug.cgi?id=3373
no longer needed)
* added managed C++ project to integrate cv2pdb with CLR (thanks to Alexander Bothe)
* dmd 2.043 uses different implementation of associative arrays, use command line
option -D 2.043 or above to produce the respective debug info
2010-06-03 Version 0.13
* adapted to mspdb100.dll which comes with VS2010
* tweaked autoexp.dat modifications to be more stable with uninitialized data
* autoexp.snippet now split into two files: autoexp.expand and autoexp.visualizer
2010-06-23 Version 0.14
* 64-integer types are now displayed as "dlong" and "ulong" instead of "__int64" and
"unsigned __int64"
* improved support for long and ulong for DMD versions before 1.057 and 2.041
* DMC also emits D-types for "long long" and "unsigned long long", these are
translated back to the correct types if command option -C is used
* now adding properties "has nested type" and "is nested type" to class/struct/union/enum types
* better support for enumerators: now added as user defined types (DMD patch needed)
2010-08-08 Version 0.15
* thanks to patches by Z3N, the resulting pdb is now usable by more debuggers
* now uses shared file access to executable
* incomplete structs/classes are now added as user defined types to avoid confusing
debugger for following symbols
* fixed name demangling of very long names
* added name demangling support for @safe/@trusted/@property/pure/nothrow/ref
* base classes are added to D/cpp-interfaces to allow viewing the virtual function
table pointer
* structs, classes and interfaces now have an internal qualifier attached that allows
the preview in autoexp.dat to show better info for structs and interfaces
2010-08-10 Version 0.16
* fixed crash when working with -C (introduced in last version)
2010-09-04 Version 0.17

2010-12-10 Version 0.19
* now converting only class pointers to references, not pointers to structs or void
* changed default D-version to 2.043 to create correct associative array type
information for recent compilers by default
2010-12-30 Version 0.20
* fixed another issue with user defined type names longer than 300 characters
* now corrects the debug info when dmc/optlink emits multiple struct definitions,
but only one UDT record.

* added command line switch -e to enable using named enumerator for D basic types
