2012-09-26Remove the `hasFnAttr' method from Function.Bill Wendling
The hasFnAttr method has been replaced by querying the Attributes explicitly. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164725 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22Tidy up a few more uses of MF.getFunction()->getName().David Blaikie
Based on CR feedback from r162301 and Craig Topper's refactoring in r162347 here are a few other places that could use the same API (& in one instance drop a Function.h dependency). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162367 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Add a getName function to MachineFunction. Use it in places that previously ↵Craig Topper
did getFunction()->getName(). Remove includes of Function.h that are no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162347 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-28Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp andBill Wendling
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. The reasoning is because the DebugInfo module is simply an interface to the debug info MDNodes and has nothing to do with analysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159312 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Add an ensureMaxAlignment() function to MachineFrameInfo (analogous toChad Rosier
ensureAlignment() in MachineFunction). Also, drop setMaxAlignment() in favor of this new function. This creates a main entry point to setting MaxAlignment, which will be helpful for future work. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158758 91177308-0d34-0410-b5e6-96231b3b80d8

needed to emit a 64-bit gp-relative relocation entry. Make changes necessary for emitting jump tables which have entries with directive .gpdword.

2012-01-27Rewrite CanShareConstantPoolEntry to be implemented in terms of theChris Lattner
mid-level constant folding APIs instead of doing its own analysis. This makes it more general (e.g. can now share a <2 x i64> with a <4 x i32>) and avoid duplicating a bunch of logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149111 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-21Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel
LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-29Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling
metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107205 91177308-0d34-0410-b5e6-96231b3b80d8
