Subject: [PATCH] d: Implement __traits(getTargetInfo, "objectFormat")
Following on from adding TARGET_D_REGISTER_OS_TARGET_INFO, this adds the
required handlers to implement `__traits(getTargetInfo, "objectFormat")'
for all platforms that have D support files.
Some back-ends (i386, rs6000, and pa) have some awarenes of the what
object format they are compiling for, so new getTargetInfo handlers have
been have added both to those back-ends as well as platform-specific
target files to override the default in the D front-end.
gcc/ChangeLog:
* config/darwin-d.c (darwin_d_handle_target_object_format): New
function.
(darwin_d_register_target_info): New function.
