2012-11-01Revert the majority of the next patch in the address space series:Chandler Carruth1-2/+2
r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. llvm-svn: 167222

2012-10-09Create enums for the different attributes.Bill Wendling1-2/+2
We use the enums to query whether an Attributes object has that attribute. The opaque layer is responsible for knowing where that specific attribute is stored. llvm-svn: 165488

2012-08-22Tidy up a few more uses of MF.getFunction()->getName().David Blaikie1-4/+4
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). llvm-svn: 162367
2012-08-22Add a getName function to MachineFunction. Use it in places that previously ↵Craig Topper1-1/+6
did getFunction()->getName(). Remove includes of Function.h that are no longer needed. llvm-svn: 162347
2012-06-28Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp andBill Wendling1-1/+1
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. llvm-svn: 159312
2012-06-19Tidy up.Chad Rosier1-17/+20
llvm-svn: 158762
2012-06-19Add an ensureMaxAlignment() function to MachineFrameInfo (analogous toChad Rosier1-1/+1
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. llvm-svn: 158758
2012-03-31Teach CodeGen's version of computeMaskedBits to understand the range metadata.Rafael Espindola1-2/+3
This is the CodeGen equivalent of r153747. I tested that there is not noticeable performance difference with any combination of -O0/-O2 /-g when compiling gcc as a single compilation unit. llvm-svn: 153817

2012-02-03Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which isAkira Hatanaka1-0/+4
needed to emit a 64-bit gp-relative relocation entry. Make changes necessary for emitting jump tables which have entries with directive .gpdword. This patch does not implement the parts needed for direct object emission or JIT. llvm-svn: 149668

llvm-svn: 149113
2012-01-27Rewrite CanShareConstantPoolEntry to be implemented in terms of theChris Lattner1-26/+26
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. llvm-svn: 149111

share entries. Add a DenseSet to MachineConstantPool for the MachineCPVs that it owns. This will hopefully fix the MC/ARM/elf-reloc-01.ll failure on the leaks bots. llvm-svn: 126218
2011-02-21Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel1-3/+1
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+) llvm-svn: 126155

2010-07-27It's better to have the arrays, which would trigger the creation of stackBill Wendling1-1/+1
protectors, to be near the stack protectors on the stack. Accomplish this by tagging the stack object with a predicate that indicates that it would trigger this. In the prolog-epilog inserter, assign these objects to the stack after the stack protector but before the other objects. llvm-svn: 109481
2010-07-23Remove too-strict assertion. We may want the vreg copy of the physical registerJim Grosbach1-1/+0
to be of a different register class. For example, in Thumb1 if the live-in is a high register, we want the vreg to be a low register. rdar://8224931 llvm-svn: 109291
