Misha Brukman	bf2857eb5c	Added the flag to mark instructions which are really 2-address instructions in X86, but would be 3-address in any normail architecture. llvm-svn: 4974	2002-12-12 23:19:11 +00:00
Brian Gaeke	9b38597288	This checkin is brought to you by the brian gaeke allnighter fund. (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	2002-12-12 15:33:40 +00:00
Brian Gaeke	250d5a3e95	Implement a lot of cast functionality (no FP or 64) llvm-svn: 4944	2002-12-06 10:49:33 +00:00
Brian Gaeke	dbc34a2a95	Target/X86/Printer.cpp: Add sizePtr function, and use it instead of " <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	2002-12-05 08:30:40 +00:00

Chris Lattner	dfc8fbf16b	- Two minor improvements to the MachineInstr class to reduce footprint and overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a bitvector. Sped up LLC a little less than 10% in a debug build! llvm-svn: 4261	2002-10-22 23:16:21 +00:00
Chris Lattner	6515ec02aa	Make sure to escape \'s when they are output llvm-svn: 4179	2002-10-15 19:56:24 +00:00

Vikram S. Adve	e4413c5804	Print "circular" warning message only in debug mode. llvm-svn: 4170	2002-10-14 16:32:49 +00:00
Vikram S. Adve	3cb2d3379d	Removed misleading const keyword. llvm-svn: 4169	2002-10-14 16:32:24 +00:00
Chris Lattner	b16f596ab4	Allow emission of names that start with an underscore. This is needed to interface with code that uses symbols in the ansi-c protected namespace. In most cases this comes from system header files, such as stdio.h. In particular, without this change, a reference to the __iob symbol is mangled into ll_iob, which is not resolved by libc. llvm-svn: 4165	2002-10-14 06:14:18 +00:00
Vikram S. Adve	c6fe6822ca	Don't try to compute the size of an "array" element if the index is 0: the size may be unknown, and is not needed. llvm-svn: 4153	2002-10-13 21:47:44 +00:00
Chris Lattner	fdf2ca9468	- Rename Instruction::FirstOp to OpsBegin, and NumOps to OpsEnd to reflect the fact that it's a range being defined. llvm-svn: 4147	2002-10-13 19:39:16 +00:00
Vikram S. Adve	7387d96d6a	Use vectors instead of hash_maps for issueGaps and conflictLists. These hash lookups were a major sink of time because they happen so often! llvm-svn: 4136	2002-10-13 00:37:46 +00:00
Vikram S. Adve	7b920c5768	Run LICM before GCSE! llvm-svn: 4135	2002-10-13 00:34:10 +00:00
Vikram S. Adve	7436df838d	Several major fixes, particularly in emitting constant aggregates: (1) Padding bytes between structure fields (for alignment) were never being emitted into the constant pool so the layout did not match! (2) In printing constants, structures containing structures or arrays were never handled. (3) Support new model for external/uninitialized/initialized globals. Uninitialized globals are no longer emitted since they are external. Initialized globals may go either in .bss or in .data. llvm-svn: 4134	2002-10-13 00:32:18 +00:00
Vikram S. Adve	032dee9564	Don't use %l0 for large operands to a SAVE since it is needed before SAVE! We now use %g1 instead since that is shared and volatile. llvm-svn: 4133	2002-10-13 00:24:06 +00:00
Vikram S. Adve	84fa49d0e5	Don't mark JMPLCALL and JMPLRET as branches. llvm-svn: 4132	2002-10-13 00:22:32 +00:00
Vikram S. Adve	c78e160ede	(1) Try to evaluate constant when multiplying 2 constants. (2) Use intelligent multiply selection code for array allocas. (3) Don't use cache padding for alloca'd stack slots! (4) Bug fix in handling call arguments: was not copying sixth FP arg to int reg. when calling a function with no prototype. llvm-svn: 4130	2002-10-13 00:18:57 +00:00

Vikram S. Adve	dc9d94262d	Make sure to handle small negative values hiding as large unsigned longs -- this is a common case created by the front-end. llvm-svn: 4127	2002-10-13 00:04:26 +00:00
Vikram S. Adve	29dd99d98b	Major fix: extract ConstantExpr nodes and decompose them into symbolic instructions so that (a) constant folding is done automatically before code generation, and (b) selection does not have to deal with them. Also, check for ConstantPointerRefs in additional to GlobalValues when creating a GEP to load a global address. llvm-svn: 4126	2002-10-13 00:01:57 +00:00
Vikram S. Adve	eb6d37c32b	Return address register should be marked as "result" for the JMPL instruction since it is defined by the instruction. llvm-svn: 3966	2002-09-28 17:00:15 +00:00
Vikram S. Adve	06742cc0e0	Live ranges for Return value and return address of a Call are no longer created here. Instead they are created in LiveRangeInfo.cpp. This simplifies the code here quite a bit. llvm-svn: 3965	2002-09-28 16:59:05 +00:00
Vikram S. Adve	1aed35b2e5	Simplified code that handles call args and rets, so it no longer needs the RegClass list to be passed in. llvm-svn: 3964	2002-09-28 16:56:59 +00:00
Vikram S. Adve	33b21ec523	Simplify Call translation slightly. llvm-svn: 3963	2002-09-28 16:55:41 +00:00
Vikram S. Adve	940f3fa91b	Overhaul integer conversions to match C++ ISO standard. Don't allow direct FP-to-uint conversion (must be eliminated by preselection). Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed. llvm-svn: 3961	2002-09-27 14:33:08 +00:00

Vikram S. Adve	59b3b6c07b	Add methods to query about the representation of LLVM quantities (e.g., constants). Useful for target-dependent LLVM transformations like Preselection. llvm-svn: 3743	2002-09-16 15:56:01 +00:00
Vikram S. Adve	571ad069cc	Don't print out global names unnecesssarily. Also, expose pass constructors so passes can be inserted by TargetMachine.cpp. llvm-svn: 3742	2002-09-16 15:54:02 +00:00
Vikram S. Adve	58678cc06e	Move all the code that creates code generation passes from Sparc.cpp to TargetMachine.cpp, since it is entirely machine-independent. Also, add options to disable optional back-end passes (preselection and instr. scheduling). llvm-svn: 3740	2002-09-16 15:39:26 +00:00
Misha Brukman	9e054e1d17	Again, including Module makes Function unnecessary. llvm-svn: 3714	2002-09-14 02:07:43 +00:00

Vikram S. Adve	b94ede185c	Significant changes to correctly spill CC registers and to correctly handle conditional move instructions: -- cpMem<->Reg functions now support CC registers (int and FP) correctly. Also, cpMem<->Reg functions now return a vector of machine instructions. -- Scratch registers must be explicitly provided to cpMem<->Reg when needed, since CC regs need one to be copied to/from memory. -- CC regs are saved to a scratch register instead of stack. -- All regs used by a instruction are now recorded in MachineInstr::regsUsed, since regs used to save values across an instruction are not obvious either from the operands or from the LiveVar sets. -- An (explicit or implicit) operand may now be both a def and a use. This is needed for conditional move operations. So an operand may need spill code both before and after the instruction. Other changes: -- Added several get{Class,Type} functions. -- Added unified-to-local register number conversion. -- class MachineCodeForBasicBlock is now an annotation on BasicBlock. -- Suggest/Color methods may modify the MachineInstr (and always did), so don't make that argument const! -- Caller-saving code doesn't need its special purpose code for handling CC registers since cpMem<->Reg handle those correctly now. llvm-svn: 2834	2002-07-08 23:23:12 +00:00

Vikram S. Adve	fa6c24db76	Numerous bug fixes: -- correct sign extensions for integer casts and for shift-by-constant instructions generated for integer multiply -- passing FP arguments to functions with more than 6 arguments -- passing FP arguments to varargs functions -- passing FP arguments to functions with no prototypes -- incorrect stack frame size when padding a section -- folding getelementptr operations with mixed array and struct indexes -- use uint64_t instead of uint for constant offsets in mem operands -- incorrect coloring for CC registers (both int and FP): interferences were being completely ignored for int CC and were considered but no spills were marked for fp CC! Also some code improvements: -- better interface to generating machine instr for common cases (many places still need to be updated to use this interface) -- annotations on MachineInstr to communicate information from one codegen phase to another (now used to pass information about CALL/JMPLCALL operands from selection to register allocation) -- all sizes and offests in class TargetData are uint64_t instead of uint llvm-svn: 2640	2002-05-19 15:25:51 +00:00

Vikram S. Adve	4bdadf3b6f	Several fixes: (1) Avoid hard-coding some register numbers. (2) Fix some incorrect branch opcodes. (3) Don't try to move int register to float register! (4) If an operand being forwarded is a constant and it doesn't fit into the immed field of the copy machine instruction, then generate a load-constant instead of a copy. (5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2". llvm-svn: 683	2001-10-01 00:12:53 +00:00
