2010-11-17Add binary emission stuff for VLDM/VSTM. This reuses theBill Wendling

2010-11-16Fix emergency spilling in LiveIntervals::spillPhysRegAroundRegDefsUses.Jakob Stoklund Olesen
Always spill the full representative register at any point where any subregister is live. This fixes PR8620 which caused the old logic to get confused and not spill anything at all. The fundamental problem here is that the coalescer is too aggressive about physical register coalescing. It sometimes makes it impossible to allocate registers without these emergency spills. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119375 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Tidy up some things in <arm_neon.h>.Bob Wilson
Stop defining types with "__neon_" prefixes and then using typedefs without the prefix; there's no reason to do that anymore. Remove types that combine multiple Neon vectors and treat them as a single long vector; they are not used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119369 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16This is the first step in adding sane error handling support to LLVMSystem.Michael J. Spencer
The system API's will be shifted over to returning an error_code, and returning other return values as out parameters to the function. Code that needs to check error conditions will use the errc enum values which are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are compatable with the error codes in WinError.h due to some magic in system_error. An example would be: if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool. handle_error(ec); } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119360 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Fix missing includes of "llvm/Analysis/Passes.h" in the tutorials. ThanksDan Gohman
for Arnaud Allard de Grandmaison for preparing a patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119351 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-16In which I discover the existence of loops. Threading an operationDuncan Sands
over a phi node by applying it to each operand may be wrong if the operation and the phi node are mutually interdependent (the testcase has a simple example of this). So only do this transform if it would be correct to perform the operation in each predecessor of the block containing the phi, i.e. if the other operands all dominate the phi. This should fix the FFMPEG snow.c regression reported by İsmail Dönmez. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119347 91177308-0d34-0410-b5e6-96231b3b80d8
