2011-08-23Fix two more instances of mis-matched operand names breaking disassembly. ↵Owen Anderson
Found by randomized testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138337 91177308-0d34-0410-b5e6-96231b3b80d8

32-bit little-endian CPU. Used by PNaCl and Emscripten. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138335 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-23Fix fpimmm->fpimm typo.Eric Christopher
Patch by Micah Villmow! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138330 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-23Update config.sub, config.guess and configure.Ivan Krasin
The motivation to do that: 1. Now, llvm would use the stock config.sub. Before that we had an uncommitted FreeBSD-related patch. Now, it has been upstreamed and comes back. It means that it would be easier to update these files in the next time (less magic knowledge) 2. Fix a typo for pseudo-CPUs: 32e[lb] -> [lb]e32, 64e[lb]->[lb]64. One of these CPUs is used for PNaCl and it was not really convenient to have a CPU that starts with a digit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138323 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-23Introduce a pass to insert vzeroupper instructions to avoid AVX toBruno Cardoso Lopes
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper" llc command line option. This is only the first step (very naive and conservative one) to sketch out the idea, but proper DFA is coming next to allow smarter decisions. Comments and ideas now and in further commits will be very appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138317 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-22Split the landing pad's edge. Then for all uses of a landingpad instruction'sBill Wendling
value, we insert a load of the exception object and selector object from memory, which is where it actually resides. If it's used by a PHI node, we follow that to where it is being used. Eventually, all landingpad instructions should have no uses. Any PHI nodes that were associated with those landingpads should be removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138302 91177308-0d34-0410-b5e6-96231b3b80d8
