2013-02-14AArch64: stop claiming that NEON registers are usable for now.Tim Northover
If vector types have legal register classes, then LLVM bypasses LegalizeTypes on them, which causes faults currently since the code to handle them isn't in place. This fixes test failures when AArch64 is the default target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175172 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-14Fix some issues with rematerialization in RegisterCoalescer when the destinationCameron Zwarich
of the copy is a subregister def. The current code assumes that it can do a full def of the destination register, but it is not checking that the def operand is read-undef. It also doesn't clear the subregister index of the destination in the new instruction to reflect the full subregister def. These issues were found running 'make check' with my next commit that enables rematerialization in more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175122 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-14Don't asume that a static function in an extern "C" block will not be mangled.Rafael Espindola
Since functions with internal linkage don't have language linkage, it is valid to overload them: extern "C" { static int foo(); static int foo(int); } So we mangle them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175120 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-13Retain the name of the new internal global that's been shrunk.Bill Wendling
It's possible (e.g. after an LTO build) that an internal global may be used for debugging purposes. If that's the case appending a '.b' to it makes it hard to find that variable. Steal the name from the old GV before deleting it so that they can find that variable again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175104 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-13For Mips 16, add the optimization where the 16 bit form of addiu sp can be usedReed Kotler
if the offset fits in 11 bits. This makes use of the fact that the abi requires sp to be 8 byte aligned so the actual offset can fit in 8 bits. It will be shifted left and sign extended before being actually used. The assembler or direct object emitter will shift right the 11 bit signed field by 3 bits. We don't need to deal with that here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175073 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-13X86: Disable generation of rep;movsl when %esi is used as a base pointer.Benjamin Kramer
This happens when there is both stack realignment and a dynamic alloca in the function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the base pointer and the next register spill will write into oblivion. Fixes PR15249 and unbreaks firefox on i386/freebsd.
