view gen/logger.cpp @ 284:70c370e97944 trunk

[svn r305] Started support for custom class allocators/deallocators. Allocators with more than one argument still need to be fixed. Removed the LLVM stacktrace code from mars.c. Moved the LLVM based default target detection code from mars.c to llvmhelpers.cpp.
