* Fix unnecessary removal of const through cast machineryDavid Blaikie2013-02-11
| | | | | | | | I have some uncommitted changes to the cast code that catch this sort of thing at compile-time but I still need to do some other cleanup before I can enable it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174853 91177308-0d34-0410-b5e6-96231b3b80d8

* Add AArch64 as an experimental target.Tim Northover2013-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174054 91177308-0d34-0410-b5e6-96231b3b80d8

* Make the contents of encoded sections SmallVector<char, N> instead ofEli Bendersky2012-12-07
| | | | | | | | | | | | | | SmallString. This makes it possible to use the length-erased SmallVectorImpl in the interface without imposing buffer size. Thus, the size of MCInstFragment is back down since a preallocated 8-byte contents buffer is enough. It would be generally a good idea to rid all the fragments of SmallString as contents, because a vector just makes more sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169644 91177308-0d34-0410-b5e6-96231b3b80d8

* Sorry for such a large commit. The summary is that only MachO cares about theRafael Espindola2010-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | actuall addresses in a .o file, so it is better to let the MachO writer compute it. This is good for two reasons. First, areas that shouldn't care about addresses now don't have access to it. Second, the layout of each section is independent. I should use this in a subsequent commit to speed it up. Most of the patch is just removing the section address computation. The two interesting parts are the change on how we handle padding in the end of sections and how MachO can get the address of a-b when a and b are in different sections. Since now the expression evaluation normally doesn't know the section address, it will think that a-b needs relocation and let the MachO writer know. Once it has computed the section addresses, it calls back the expression evaluation with the section addresses to resolve these expressions. The remaining problem is the handling of padding. Currently it will create a special alignment fragment at the end. Since that fragment doesn't update the alignment of the section, it needs the real address to be computed. Since now the layout will not compute a-b with a and b in different sections, the only effect that the special alignment fragment has is update the address size of the section. This can also be done by the MachO writer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121076 91177308-0d34-0410-b5e6-96231b3b80d8
