2011-04-07Fixed a bug where missing EDInstInfo would causeSean Callanan
tokenization to crash and burn. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129051 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-05An MCDisassembler has the option to not implementShantonu Sen
getEDInfo(), in which case this code would dereference NULL. EDInst can already handle NULL info, so avoid the dereference and pass NULL through. Reviewed by Sean Callanan git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128904 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-28Again adding a C API to the disassembler for use by such tools as Darwin'sKevin Enderby
otool(1), this time with the needed fix for case sensitive file systems :) . This is a work in progress as the interface for producing symbolic operands is not done. But a hacked prototype using information from the object file's relocation entiries and replacing immediate operands with MCExpr's has been shown to work with no changes to the instrucion printer. These APIs will be moved into a dynamic library at some point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128415 91177308-0d34-0410-b5e6-96231b3b80d8
