This is the same as in PR #1269. The Ir-Types may be initialized
twice (due to pointers, forward references etc.).
This commit fixes hopefully all instances of this problem, using
the same approach in each factory function.
This fixes issue #1112.
The constructor of IrTypeSArray() calls sarray2llvm(). This function calls
DtoMemType() which may recursively try to construct another IrTypeSArray
for the same type. To prevent this the call to sarray2llvm() is moved
out
of the constructor into the factory method and an explicit check is added.
This fixes issue #1266.
On a PowerPC target the datatype real is mapped to PPC 128bit doubledouble type.
Please note that this yet does not work if you cross compile from a different
architecture.
This also allows us to enable the assert in IrType::IrType.
Unfortunately, this is mostly a "peace of mind" commit, there
doesn't seem to have been a bug actually caused by the transitory
duplicate IrTypePointer/IrTypeStruct instances.
The remaining xyz2llvm static methods are not exactly pretty,
they should probably just be folded into get.
This is based on Item 2 of "More Effective C++". In general, the C++ cast operators are more expressive and easy to find,
e.g. by grep. Using const_cast also shuts up some compiler warnings.
Removed use of dyn_cast, llvm no compiles
without exceptions and rtti by
default. We do need exceptions for the libconfig stuff, but rtti isn't
necessary (anymore).
Debug info needs to be rewritten, as in LLVM 2.7 the format has
completely changed. To have something to look at while rewriting, the
old code has been wrapped inside #ifndef DISABLE_DEBUG_INFO , this means
that you have to define this to compile at the moment.
Updated tango 0.99.9 patch to include updated EH runtime code, which is
needed for LLVM 2.7 as well.
Added -v-cg switch, which right now just prints "codegen: module.name (module/name.d)" to stdout, this can really help figuring out where, in some complex build command, things go wrong.
Fixed function literals in static initializers.
Changed alignment of delegates from 2*PTRSIZE to just PTRSIZE.
Changed errors to go to stderr instead of stdout.
Fairly major rewriting of struct/union/class handling, STILL A BIT BUGGY !!!
