2012-08-25Fix a CodeGen bug where we would skip zero-initialization forEli Friedman
array new with a non-trivial constructor. Pointed out in PR13380. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162643 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16Elide copy construction in new expressions. PR11757.Eli Friedman

2011-12-09Make array new on a pointer to data member type work correctly. PR11523.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146291 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Convert the standard default-construction loops to use phis andJohn McCall
partial destruction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135033 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27When instantiating a C++ "new" expression, don't fake source locationsDouglas Gregor
for the '(' and ')' around the initializer unless we actually have an initializer. Fixes PR10197, an issue where we were value-initializing rather than default-initializing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133913 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-16Don't actually emit calls to the reserved global placement new and deleteJohn McCall
operators; their semantics are guaranteed by the language. If someone wants to argue that freestanding compiles shouldn't recognize this, I might be convinceable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131395 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Fix a few more ConvertTypes that should be ConvertTypeForMems, fixingDouglas Gregor
two regressions in Boost.Config. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112908 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Abstract IR generation of array cookies into the C++ ABI class andJohn McCall
implement ARM array cookies. Also fix a few unfortunate bugs: - throwing dtors in deletes prevented the allocation from being deleted - adding the cookie to the new[] size was not being considered for overflow (and, more seriously, was screwing up the earlier checks) - deleting an array via a pointer to array of class type was not causing any destructors to be run and was passing the unadjusted pointer to the deallocator - lots of address-space problems, in case anyone wants to support free store in a variant address space :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112814 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-26Fix miscompilation. The cookie was not used when new'ing arrays with ↵Argyrios Kyrtzidis
multiple dimensions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112188 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-25Fix miscompilation. The custom new[]/delete[] methods were not getting ↵Argyrios Kyrtzidis
called for arrays with more than 1 dimension. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112107 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Make sure to add MallocAttr to explicitly-declared operator new/new[]Douglas Gregor
when -fassume-sane-operator-new. Patch by Tom Jablin! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111363 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-21Implement zero-initialization for array new when there is anDouglas Gregor
initializer of (). Make sure to use a simple memset() when we can, or fall back to generating a loop when a simple memset will not suffice. Fixes <rdar://problem/8212208>, a regression due to my work in r107857. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108977 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
