Fix PPC ISD::Declare isel and eliminate the need for PPCTargetLowering::LowerGlobalAddress to check if isVerifiedDebugInfoDesc() is true. Given the recent changes, it would falsely return true for a lot of GlobalAddressSDNode's.

rename a file to follow naming conventions.

Fix PR3149. If an early clobber def is a physical register and it is tied to an input operand, it effectively extends the live range of the physical register. Currently we do not have a good way to represent this.

172 %ECX = MOV32rr %reg1039 180 INLINEASM , 10, %EAX, 14, %ECX, 9, %EAX, 36, , 1, %reg0, 0, 9, %ECX, 36, , 1, %reg0, 0 188 %EAX = MOV32rr %EAX 196 %ECX = MOV32rr %ECX 204 %ECX = MOV32rr %ECX 212 %EAX = MOV32rr %EAX 220 %EAX = MOV32rr %EAX 228 %reg1039 = MOV32rr %ECX The early clobber operand ties ECX input to the ECX def. The live interval of ECX is represented as this: %reg20,inf = [46,47:1)[174,230:0) 0@174-(230) 1@46-(47) The right way to represent this is something like %reg20,inf = [46,47:2)[174,182:1)[181:230:0) 0@174-(182) 1@181-230 @2@46-(47) Of course that won't work since that means overlapping live ranges defined by two val#. The workaround for now is to add a bit to val# which says the val# is redefined by a early clobber def somewhere. This prevents the move at 228 from being optimized away by SimpleRegisterCoalescing::AdjustCopiesBackFrom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61259 91177308-0d34-0410-b5e6-96231b3b80d8

Fix bug 3202.

The EH_frame and .eh symbols are now private, except for darwin9 and earlier. The patch also fixes the definition of PrivateGlobalPrefix on pcc linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61242 91177308-0d34-0410-b5e6-96231b3b80d8

We have decided not to support inline asm where an output operand with a matching input operand with incompatible type (i.e. either one is a floating point and the other is an integer or the sizes of the types differ). SelectionDAGBuild will catch these and exit with an error.

Re-did 60519. It turns out Darwin's handling of hidden visibility symbols are a bit more complicate than I expected. Both declarations and weak definitions still need a stub indirection. However, the stubs are in data section and they contain the addresses of the actual symbols.

Remove a (what appears to be) overly strict assertion. Here is what happened:

1. ppcf128 select is expanded to f64 select's. 2. f64 select operand 0 is an i1 truncate, it's promoted to i32 zero_extend. 3. f64 select is updated. It's changed back to a "NewNode" and being re-analyzed. 4. f64 select operands are being processed. Operand 0 is a "NewNode". It's being expunged out of ReplacedValues map. 5. ExpungeNode tries to remap f64 select and notice it's a "NewNode" and assert. Duncan, please take a look. Thanks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60443 91177308-0d34-0410-b5e6-96231b3b80d8
