Change Requests Status

Change Request	Change Status	Change Notes
GCC steering committee approval of accepting the FE contribution and appointing a FE maintainer.	Issue raised
Create a GDC svn/git branch on GCC for platform integration testing.	Proposal	Requires approval of the SC.
GCC-specific files in D runtime (gcc.builtins, etc) should have the GCC Runtime Library Exception notice.	Done	GDC#493
There appear to be various GPLv2 notices with old FSF addresses. Where those are on source files (as opposed to generated files), they should be updated to the usual GPLv3+ notice for GCC.	Done	GDC#493, GDC#495
DMD front end has functions with names such as error, but no useful i18n will actually occur because GDC formats the messages with xvasprintf before passing to the common diagnostic code. The DMD front end should be disabled, to prevent exgettext from extracting and putting messages in gcc.pot that won't actually be translated.	Needs Action	Add DMD sources to list of sources disabled for translation. The file that controls this appears to be gcc/po/EXCLUDES. Improve GDC diagnostic to use diagnostic_report_diagnostic() directly, rather than just being a high level wrapper around gcc error_at()/warning_at().
Target::critsecsize should have its code belonging to the gcc/config/ configuration for each target as a target hook returning the required information, not in the D front end code.	Needs Action	See list of changes required to implement. For the worst case (unsupported target), should set the target hook to default to returning a large enough buffer size, e.g: 64.

Other Maintenance Tasks

Change Request	Change Status	Change Notes
Create a dmd-cxx git branch on dlang/dmd to host GDC's forked C++ front end sources.	Needs Action	Create a new branch based on dmd/2.068 Merge all changes during 2.069 development up until the switch-over. Merge or cherry-pick in backports that have been applied on the GDC branch.
