2009-09-12Merge 81308 from mainline.Tanya Lattner
Make sure the memory range is writable before memset'ing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81638 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25Added a test and fixed a bug in BumpPtrAllocator relating to large alignmentReid Kleckner
values. Hopefully this fixes PR4622. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77088 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-24Switch to raw_ostream.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76943 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Re-committing changes from r76825 to BumpPtrAllocator with a fix and tests forReid Kleckner
an off-by-one error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76891 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Reverting r76825 and r76828, since they caused clang runtime errors and some ↵Reid Kleckner
build failure involving memset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76838 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23add header for 'memset'.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76837 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Parameterize the BumpPtrAllocator over a slab allocator. It defaults to usingReid Kleckner
malloc, so there should be no functional changes to other code. These changes are necessary since I have plans to use this allocator in the JIT memory manager, and it needs a special allocator. I also added some tests which helped me pinpoint some bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76825 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-28Fold the useful features of alist and alist_node into ilist, andDan Gohman
a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54146 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-07Add some basic Pool-allocation infrastructure. This adds a Recycler class,Dan Gohman
for handling bookkeeping for deleted objects, as well as the alist class template, for keeping lists of objects allocated from Recyclers, and some related utilities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53210 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-05Fix more -Wshorten-64-to-32 warnings.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50659 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-28Fix a pointer-arithmetic bug that caused 64-bit host pointer values toDan Gohman
be truncated to 32 bits. This fixes the recent Benchmarks/McCat/09-vor regression on x86-64, among other things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50372 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-28Bug fix in BumpPtrAllocator: don't assume that all objects have the same ↵Ted Kremenek
alignment. "Bump" of the pointer for the next allocated object to be of the specified alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50362 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Remove attribution from file headers, per discussion on llvmdev.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-08Smarter Reset(). Instead of deallocating all memory regions and reallocate theEvan Cheng
first region, just deallocate all but the last region in the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41782 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-05Added Reset() to free all allocated memory regions and reset state to be the ↵Evan Cheng
same as right after ctor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41728 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-23Avoid TBAA issue.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34539 91177308-0d34-0410-b5e6-96231b3b80d8
2006-12-07Don't use <sstream> in Streams.h but <iosfwd> instead.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32340 91177308-0d34-0410-b5e6-96231b3b80d8
2006-12-07Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, areBill Wendling
now cerr, cout, and NullStream resp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32298 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-26Removed #include <iostream> and replace with llvm_* streams.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31927 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-08Include llvm/Support/DataTypes.h to define intptr_t.John Criswell
This fixes the build on OpenBSD and potentially other systems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31550 91177308-0d34-0410-b5e6-96231b3b80d8
2006-10-29Add a new llvm::Allocator abstraction, which will be used by a containerChris Lattner
I'm about to add. This is similar to, but necessarily different than, the STL allocator class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31285 91177308-0d34-0410-b5e6-96231b3b80d8
