Improve FastISel's handling of truncates to i1, and implement ptrtoint and inttoptr in X86FastISel. These casts aren't always handled in the generic FastISel code because X86 sometimes needs custom code to do truncation and zero-extension. llvm-svn: 66988 2009-03-14 07:53:06 +08:00			`; RUN: llvm-as < %s \| llc -march=x86 -fast-isel -fast-isel-abort`

Handle x86 truncate to i8 with target hook for now. llvm-svn: 55877 2008-09-07 16:47:42 +08:00
