Nate Begeman	9d224ae29b	Support indexed loads and stores. This drops Shootout/matrix time from 18.8 to 14.8 seconds. The Pattern ISel is now often faster than the Simple ISel, esp. on memory intensive code. llvm-svn: 20973	2005-04-01 04:45:11 +00:00
Nate Begeman	af7c6366d7	Implement FP_TO_SINT and FP_TO_UINT llvm-svn: 20972	2005-04-01 02:59:27 +00:00

Andrew Lenharth	7db3834ecf	PCMarker support for DAG and Alpha llvm-svn: 20965	2005-03-31 21:24:06 +00:00
Duraid Madina	47fed18416	Assorted fixes: * Stop being pessimistic about output register allocation * Start to handle function descriptors: compute target GPs and so on when doing indirect calls etc. Not there yet, though. For the moment, we try to use _indirect_ branches wherever possible, to stress test function descriptors. * FP divide-by-zero should work now * add varargs (it doesn't work, though) At this point, all of SingleSource passes (modulo C++ tests that are due to issues with the CFE, see note in the README.) Much of MultiSource also passes although there's still a ton of bugs around. Something for me to work on tomorrow, then. :) llvm-svn: 20960	2005-03-31 12:31:11 +00:00
Duraid Madina	f2d1865c74	* declare local common symbols as such (.lcomm, not merely .common) * begin great adventure into correct function descriptor materialization llvm-svn: 20956	2005-03-31 07:40:24 +00:00

Duraid Madina	11ff0a2a5f	add what we need to fudge a 'floating point conditional move', this is used to get FP div-by-zero working properly (shunt the right answer depending on how frcpa sets its predicate output) llvm-svn: 20954	2005-03-31 07:32:32 +00:00
Nate Begeman	17ff2b3a87	Pass the correct values to the chain argument for node construction during LowerCallTo. Handle ISD::ADD in SelectAddr, allowing us to have nonzero immediates for loads and stores, amazing! llvm-svn: 20946	2005-03-31 02:05:53 +00:00
Nate Begeman	de4aac1374	Rewrite LowerCallTo and Select(ISD::CALL) to properly handle float varargs Tell the SelectionDAG ISel to expand SEXTLOAD of i1 and i8, rather than complicate the code in ISD::SEXTLOAD to do it by hand Combine the FP and Int ISD::LOAD codegen Generate better code for constant pool loads As a result, all of Shootout, and likely many other programs are now working. llvm-svn: 20945	2005-03-31 00:15:26 +00:00
Nate Begeman	9c5480beeb	Fix calls whose arguments fit entirely in registers to not break the Chain. Implement SINT_TO_FP and UINT_TO_FP Remove some dead code from the simple ISel llvm-svn: 20944	2005-03-30 19:38:35 +00:00

Nate Begeman	ec87399dac	Fix external symbol printing in the AsmPrinter. Tell the ISel that we don't support things like memcpy directly. This allows a handful of the Shootout programs to work, yay! llvm-svn: 20939	2005-03-30 01:45:43 +00:00
Chris Lattner	46c4246df1	don't depend on the cfg being set up yet llvm-svn: 20936	2005-03-30 01:10:00 +00:00
Nate Begeman	8eddad3985	Fix BranchCC (it's still dumb), and implement FP select (also dumb) llvm-svn: 20935	2005-03-29 22:48:55 +00:00

Tanya Lattner	7edde71619	Dependence analyzer that just determines dependences within a loop for loads and stores using alias analysis. llvm-svn: 20930	2005-03-29 20:33:42 +00:00

Nate Begeman	6b0fbf811f	Fix that pesky floats in integer regs problem by assigning the f32 type to the correct register class. Also remove the loading of float data into int regs part of varargs; it will need to be implemented differently later. llvm-svn: 20857	2005-03-26 08:25:22 +00:00
Nate Begeman	31d175d1e5	Get closer to having varargs working. There's still something strange going on with copies between floating point and integer register files being generated. Once that is solved, varargs will be done. llvm-svn: 20856	2005-03-26 07:46:36 +00:00
Nate Begeman	69742e6ea1	Make 64bit args and float args work correct with calls. Thanks to Chris for explaining EXTRACT_ELEMENT to me. llvm-svn: 20847	2005-03-26 02:17:46 +00:00

Chris Lattner	fbd1f8e4fd	Add a hook to find out how the target handles shift amounts that are out of range. Either they are undefined (the default), they mask the shift amount to the size of the register (X86, Alpha, etc), or they extend the shift (PPC).

Chris Lattner	b3edb09ede	Rely on the code in MatchAddress to do this work. Otherwise we fail to match (X+Y)+(Z << 1), because we match the X+Y first, consuming the index register, then there is no place to put the Z. llvm-svn: 19652	2005-01-18 02:25:52 +00:00
Chris Lattner	ce2e0125dc	Fix a problem where probing for addressing modes caused expressions to be emitted too early. In particular, this fixes Regression/CodeGen/X86/regpressure.ll:regpressure3. This also improves the 2nd basic block in 164.gzip:flush_block, which went from .LBBflush_block_1: # loopentry.1.i movzx %EAX, WORD PTR [dyn_ltree + 20] movzx %ECX, WORD PTR [dyn_ltree + 16] mov DWORD PTR [%ESP + 32], %ECX movzx %ECX, WORD PTR [dyn_ltree + 12] movzx %EDX, WORD PTR [dyn_ltree + 8] movzx %EBX, WORD PTR [dyn_ltree + 4] mov DWORD PTR [%ESP + 36], %EBX movzx %EBX, WORD PTR [dyn_ltree] add DWORD PTR [%ESP + 36], %EBX add %EDX, DWORD PTR [%ESP + 36] add %ECX, %EDX add DWORD PTR [%ESP + 32], %ECX add %EAX, DWORD PTR [%ESP + 32] movzx %ECX, WORD PTR [dyn_ltree + 24] add %EAX, %ECX mov %ECX, 0 mov %EDX, %ECX to .LBBflush_block_1: # loopentry.1.i movzx %EAX, WORD PTR [dyn_ltree] movzx %ECX, WORD PTR [dyn_ltree + 4] add %ECX, %EAX movzx %EAX, WORD PTR [dyn_ltree + 8] add %EAX, %ECX movzx %ECX, WORD PTR [dyn_ltree + 12] add %ECX, %EAX movzx %EAX, WORD PTR [dyn_ltree + 16] add %EAX, %ECX movzx %ECX, WORD PTR [dyn_ltree + 20] add %ECX, %EAX movzx %EAX, WORD PTR [dyn_ltree + 24] add %ECX, %EAX mov %EAX, 0 mov %EDX, %EAX ... which results in less spilling in the function. This change alone speeds up 164.gzip from 37.23s to 36.24s on apoc. The default isel takes 37.31s. llvm-svn: 19650	2005-01-18 01:06:26 +00:00

Chris Lattner	d188e03011	Take register pressure into account when we have to decide whether to evaluate the LHS or the RHS of an operation first. This causes good things to happen. For example, instead of compiling a loop to this: .LBBstrength_result7_1: # loopentry movl 16(%esp), %edi movl (%edi), %edi ;;; LOAD movl (%ecx), %ebx movl $2, (%eax,%ebx,4) movl (%edx), %ebx movl %esi, %ebp addl $21, %ebp addl $42, %esi cmpl $0, %edi ;;; USE cmovne %esi, %ebp cmpl %ebp, %ebx movl %ebp, %esi jg .LBBstrength_result7_1 We now compile it to this: .LBBstrength_result7_1: # loopentry movl %edi, %ebx addl $42, %ebx addl $21, %edi movl (%ecx), %ebp ;; LOAD cmpl $0, %ebp ;; USE cmovne %ebx, %edi movl (%edx), %ebx movl $2, (%eax,%ebx,4) movl (%esi), %ebx cmpl %edi, %ebx jg .LBBstrength_result7_1 Which reduces register pressure enough (in this case) to avoid spilling in the loop. As another example, consider the CodeGen/X86/regpressure.ll testcase. We used to generate this code for both cases: regpressure1: subl $32, %esp movl %esi, 12(%esp) movl %edi, 8(%esp) movl %ebx, 4(%esp) movl %ebp, (%esp) movl 36(%esp), %ecx movl (%ecx), %eax movl 4(%ecx), %edx movl %edx, 24(%esp) movl 8(%ecx), %edx movl %edx, 16(%esp) movl 12(%ecx), %edx movl 16(%ecx), %esi movl 20(%ecx), %edi movl 24(%ecx), %ebx movl %ebx, 28(%esp) movl 28(%ecx), %ebx movl 32(%ecx), %ebp movl %ebp, 20(%esp) movl 36(%ecx), %ecx imull 24(%esp), %eax imull 16(%esp), %eax imull %edx, %eax imull %esi, %eax imull %edi, %eax imull 28(%esp), %eax imull %ebx, %eax imull 20(%esp), %eax imull %ecx, %eax movl (%esp), %ebp movl 4(%esp), %ebx movl 8(%esp), %edi movl 12(%esp), %esi addl $32, %esp ret This code is basically trying to do all of the loads first, then execute all of the multiplies. Because we run out of registers, lots of spill code happens. We now generate this code for both cases: regpressure1: movl 4(%esp), %ecx movl (%ecx), %eax movl 4(%ecx), %edx imull %edx, %eax movl 8(%ecx), %edx imull %edx, %eax movl 12(%ecx), %edx imull %edx, %eax movl 16(%ecx), %edx imull %edx, %eax movl 20(%ecx), %edx imull %edx, %eax movl 24(%ecx), %edx imull %edx, %eax movl 28(%ecx), %edx imull %edx, %eax movl 32(%ecx), %edx imull %edx, %eax movl 36(%ecx), %ecx imull %ecx, %eax ret which is much nicer (when we fold loads into the muls it will be even better). The old instruction selector used to produce the good code for regpressure1 but not for regpressure2, as it depended on the order of operations in the LLVM code. llvm-svn: 19449	2005-01-11 03:11:44 +00:00

Chris Lattner	2231d21dad	Fix several bugs in 'op x, imm' handling. Foremost is that we now emit addi r3, r3, -1 instead of addi r3, r3, 1 for 'sub int X, 1'. Secondarily, this fixes several cases where we could crash given an unsigned constant.

Nate Begeman	6405f5e9b3	Enable optimization suggested by Chris Lattner to not emit reloc stubs for static global variables whose addresses are taken. This allows us to convert the following code for taking the address of a static function foo addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb") lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2) which also includes linker stub code emitted at the end of the .s file not shown here, and replace it with this: addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb") la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2) which in addition to not needing linker help, also has no load instruction.

Chris Lattner	ebbfaa3db8	* Rename existing relocations to be more specific * Add relocations for refernces to non-lazy darwin stubs and implement them correctly.
