Add lock prefix support to x86. Also add the instructions necessary for the atomic ops. They are still marked pseudo, since I cannot figure out what format to use, but they are the correct opcode. llvm-svn: 47795

stack slot and store if the SINT_TO_FP is actually legal. This allows us to compile: double a(double b) {return (unsigned)b;} to: _a: cvttsd2siq %xmm0, %rax movl %eax, %eax cvtsi2sdq %rax, %xmm0 ret instead of: _a: subq $8, %rsp cvttsd2siq %xmm0, %rax movl %eax, %eax cvtsi2sdq %rax, %xmm0 addq $8, %rsp ret crazy. llvm-svn: 47660

_test: movl %edi, %eax ret instead of: _test: movl $4294967295, %ecx movq %rdi, %rax andq %rcx, %rax ret It would be great to write this as a Pat pattern that used subregs instead of a 'pseudo' instruction, but I don't know how to do that in td files. llvm-svn: 47658

GOT-style position independent code. Before only tail calls to protected/hidden functions within the same module were optimized. Now all function calls are tail call optimized. llvm-svn: 47594

calls. Before arguments that could overwrite each other were explicitly lowered to a stack slot, not giving the register allocator a chance to optimize. Now a sequence of copyto/copyfrom virtual registers ensures that arguments are loaded in (virtual) registers before they are lowered to the stack slot (and might overwrite each other). Also parameter stack slots are marked mutable for (potentially) tail calling functions. llvm-svn: 47593
