* lib/Target/X86/InstSelectSimple.cpp: Start counting arguments with 2,Brian Gaeke2002-12-131-8/+9
| | | | | | | | | | | | | | | | | because arguments start two stack slots off of EBP. Break out of the for loop once the argument is found. Increment the counter at the end of the loop instead of the beginning. Use addRegOffset and compute the scale * index part at compile time instead of using the fancy load instruction. Just because an instruction set has wacky addressing modes doesn't mean we ought to use them (at least, if you believe Dave Patterson). lib/Target/X86/X86InstrBuilder.h: Add some comments. test/Regression/Jello/test-loadstore.ll: Let main return int 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4999 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (lib/Target/X86) InstSelectSimple.cpp: Include llvm/DerivedTypes.h and iostream. Refactor visitMul out into a wrapper around doMultiply(), so that we can do multiplications on temporary values when we are doing getelementptrs. Refactor part of getReg out into makeAnotherReg, so that we can create registers willy-nilly to hold temporary values, when we are doing getelementptrs. Add stub implementations of visitMallocInst and visitAllocaInst. Add initial implementation of visitGetElementPtrInst. In copyConstantToRegister: We throw a *lot* of our asserts here. So, when we want to throw an assert, print out to stderr whatever expr or whatever constant made us barf. Support copying ConstantPointerNull to register, using a move immediate of zero. Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings of the numbers in the other instruction names. All uses modified. Teach visitCallInst to extract byte- and short-class return values from subregs of EAX. Add a FIXME note about how we would do it for float-class return values. Add a FIXME note about how we would cast float to int and back. X86InstrInfo.def: Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings of the numbers in the other instruction names. All uses modified. (tools/jello) GlobalVars.cpp: Include iostream. If we have to emit a floating-point constant to memory, gamble and use the same method as for ints. If we have to emit a ConstantPointerNull to memory, try using a "void *" and "NULL". Otherwise, if we are going to throw an assert, print out whatever constant made us barf, first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4973 91177308-0d34-0410-b5e6-96231b3b80d8
