* [Stack Alignment] emit warning instead of a hard errorManman Ren2013-02-042-5/+5
| | | | | | | | | | | | Per discussion in rdar://13127907, we should emit a hard error only if people write code where the requested alignment is larger than achievable and assumes the low bits are zeros. A warning should be good enough when we are not sure if the source code assumes the low bits are zeros. rdar://13127907 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174336 91177308-0d34-0410-b5e6-96231b3b80d8
* Initial cleanups of the param-attribute code in the bitcode reader/writer.Bill Wendling2013-02-045-66/+59
| | | | | | | | | | Rename the PARAMATTR_CODE_ENTRY to PARAMATTR_CODE_ENTRY_OLD. It will be replaced by another encoding. Keep around the current LLVM attribute encoder/decoder code, but move it to the bitcode directories so that no one's tempted to use them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174335 91177308-0d34-0410-b5e6-96231b3b80d8

* SelectionDAG: Teach FoldConstantArithmetic how to deal with vectors.Benjamin Kramer2013-02-047-55/+129
| | | | | | | | | | | | | | | | | This required disabling a PowerPC optimization that did the following: input: x = BUILD_VECTOR <i32 16, i32 16, i32 16, i32 16> lowered to: tmp = BUILD_VECTOR <i32 8, i32 8, i32 8, i32 8> x = ADD tmp, tmp The add now gets folded immediately and we're back at the BUILD_VECTOR we started from. I don't see a way to fix this currently so I left it disabled for now. Fix some trivially foldable X86 tests too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174325 91177308-0d34-0410-b5e6-96231b3b80d8

* Pass CPPFLAGS/CFLAGS/CXXFLAGS from the environment of configure toPatrik Hagglund2013-02-044-5/+29
| | | | | | | | | | | | | | | | | Makefile.config. This is implied at the bottom of the help text of configure (besides CC/CXX/LDFLAGS, already passed to Makefile.config). For backward compatibility, the values of CFLAGS and CXXFLAGS defaults to empty, overriding the default values provided by autoconf (for example, '-g -O2' when CC=gcc'). $(CPP) is not used by our makefiles. Therefore, the value of CPP is not passed to Makefile.config, despite beeing mentioned by 'configure --help'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174313 91177308-0d34-0410-b5e6-96231b3b80d8
* More MSan/ASan annotations.Evgeniy Stepanov2013-02-046-9/+24
| | | | | | | | | | | | | | | This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains fixes for 2 issues: - X86JIT reads return address from stack, which MSan does not know is initialized. - bugpoint tests run binaries with RLIMIT_AS. This does not work with certain Sanitizers.

* ARM cost model: Penalize insertelement into D subregistersArnold Schwaighofer2013-02-043-0/+65
| | | | | | | | | | | Swift has a renaming dependency if we load into D subregisters. We don't have a way of distinguishing between insertelement operations of values from loads and other values.

| | | | | | | | | | | | Improve performance of iterating over children and accessing the member file buffer by caching the file size and moving code out to the header.

This is in preparation for adding the new keyword externally_initialized.

| | | | | | | | | | The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason.
