| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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. llvm-svn: 4973
* Implement a lot of cast functionality (no FP or 64)Brian Gaeke2002-12-061-34/+62

* Target/X86/Printer.cpp: Add sizePtr function, and use it instead ofBrian Gaeke2002-12-053-111/+143
| | | | | | | | | | | | | | | | | | " <SIZE> PTR " string when emitting assembly. Target/X86/X86InstrInfo.def: Tidy up a bit: Squashed everything down to 118 chars wide, wrapping lines so that comment is at the same point on each line. Rename "NoImpRegs" as "NoIR". (most instructions have NoImpRegs twice on a line, so this saves 10 columns). Also, annotate various instructions with flags for size of memory operand. (MemArg16, MemArg32, MemArg64, etc.) Target/X86/X86InstrInfo.h: Define flags for size of memory operand. (MemArg16, MemArg32, MemArg64, etc.) llvm-svn: 4932
