* I mis-interpreted the MCDisassembler's intended dependencies. Now to fixChandler Carruth2011-07-311-2/+9
| | | | | | | | | | | | | them properly. Specifically, the disassembler clearly attempts to initialiaze all TargetInfo, MCTargeDesc, AsmParser, and Disassembler sublibraries of registered targets. This makes the CMakeLists accurately reflect this intent in the code. This should fix the last of the link errors that I have gotten reports of on OS X, but if anyone continues to see link errors, continue to pester me and I'll look into it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136603 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | This adds the 'resume' instruction class, IR parsing, and bitcode reading and writing. The 'resume' instruction resumes propagation of an existing (in-flight) exception whose unwinding was interrupted with a 'landingpad' instruction (to be added later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136589 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "Don't check liveness of unallocatable registers."Jakob Stoklund Olesen2011-07-302-11/+4
| | | | | | | The ARM target depends on CPSR liveness being tracked after register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136548 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't check liveness of unallocatable registers.Jakob Stoklund Olesen2011-07-292-4/+11
| | | | | | | | | | | | This includes registers like EFLAGS and ST0-ST7. We don't check for liveness issues in the verifier and scavenger because registers will never be allocated from these classes. While in SSA form, we do care about the liveness of unallocatable unreserved registers. Liveness of EFLAGS and ST0 neds to be correct for MachineDCE and MachineSinking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136541 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an isSSA() flag to MachineRegisterInfo.Jakob Stoklund Olesen2011-07-293-1/+8
| | | | | | | | | | | | | This flag is true from isel to register allocation when the machine function is required to be in SSA form. The TwoAddressInstructionPass and PHIElimination passes clear the flag. The SSA flag wil be used by the machine code verifier to check for SSA form, and eventually an assertion can enforce it in +Asserts builds. This will catch the common target error of creating machine code with multiple defs of a virtual register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136532 91177308-0d34-0410-b5e6-96231b3b80d8
