view tango/lib/compiler/llvmdc/typeinfo/ti_Along.d @ 213:7816aafeea3c trunk

[svn r229] Updated the object.d implementation to the latest Tango. Fixed a bunch of the built-in typeinfos for arrays, they did not inherit TypeInfo_Array. Applied patch to tango/text/convert/Layout.d by fvbommel, closes #47 . Cleaned up some type code. Replaced uses of llvm::Type with LLType (a typedef), same for Value and Constant. Fixed a few cases where typeinfo for user structs could be emitted multiple times, seems to still be some cases of this :/
