2008-11-05Some code simplification. It now doesn't generate a prologue if the epilogueBill Wendling
isn't going to be generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58734 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-04fix memory leak in pass manager when adding an analysis pass that already ↵Nuno Lopes
existed. as pass manager takes ownership of the added passes, it has to delete the pass if it isnt added to the pass list tweak the opt tool so that it doesnt access a Pass after the ownership was taken by the pass manager git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58730 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-04Small simplification of the stack guard type.Bill Wendling

2008-11-04- Add a "getOrInsertGlobal" method to the Module class. This acts similarly toBill Wendling
"getOrInsertFunction" in that it either adds a new declaration of the global and returns it, or returns the current one -- optionally casting it to the correct type. - Use the new getOrInsertGlobal in the stack protector code. - Use "splitBasicBlock" in the stack protector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58727 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-04Update in response to feedback from Chris:Bill Wendling
- Use enums instead of magic numbers. - Rework algorithm to use the bytes size from the target to determine when to emit stack protectors. - Get rid of "propolice" in any comments. - Renamed an option to its expanded form. - Other miscellanenous changes. More changes will come after this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58723 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-04For some targets, it's not possible to place GVs in the same memory buffer ↵Evan Cheng
as the MachineCodeEmitter allocated memory. Code and data has different read / write / execution privilege requirements. This is a short term workaround. The current solution is for the JIT memory manager to manage code and data memory separately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58688 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-04Initial checkin for stack protectors. Here's what it does:Bill Wendling
* The prologue is modified to read the __stack_chk_guard global and insert it onto the stack. * The epilogue is modified to read the stored guard from the stack and compare it to the original __stack_chk_guard value. If they differ, then the __stack_chk_fail() function is called. * The stack protector needs to be first on the stack (after the parameters) to catch any stack-smashing activities. Front-end support will follow after a round of beta testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58673 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-03Fix some ppcf128 regressions: make ExpandFloatRes_LOADDale Johannesen

2008-11-03Make VAARG promotion work correctly with large funkyDuncan Sands
sized integers like i129, and also reduce the number of assumptions made about how vaarg is implemented. This still doesn't work correctly for small integers like (eg) i1 on x86, since x86 passes each of them (essentially an i8) in a 4 byte stack slot, so the pointer needs to be advanced by 4 bytes not by 1 byte as now. But this is no longer a LegalizeTypes problem (it was also wrong in LT before): it is a bug in the operation expansion in LegalizeDAG: now LegalizeTypes turns an i1 vaarg into an i8 vaarg which would work fine if only the i8 vaarg was turned into correct code later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58635 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-03Turn floating point IVs into integer IVs where possible.Devang Patel
This allows SCEV users to effectively calculate trip count. LSR later on transforms back integer IVs to floating point IVs later on to avoid int-to-float casts inside the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58625 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-03Change how extended types are represented in MVTs. Instead of fiddlingDan Gohman
bits, use a union of a SimpleValueType enum and a regular Type*. This increases the size of MVT on 64-bit hosts from 32 bits to 64 bits. In most cases, this doesn't add significant overhead. There are places in codegen that use arrays of MVTs, so these are now larger, but they're small in common cases. This eliminates restrictions on the size of integer types and vector types that can be represented in codegen. As the included testcase demonstrates, it's now possible to codegen very large add operations. There are still some complications with using very large types. PR2880 is still open so they can't be used as return values on normal targets, there are no libcalls defined for very large integers so operations like multiply and divide aren't supported. This also introduces a minimal tablgen Type library, capable of handling IntegerType and VectorType. This will allow parts of TableGen that don't depend on using SimpleValueType values to handle arbitrary integer and vector types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58623 91177308-0d34-0410-b5e6-96231b3b80d8
