2005-07-19Remove unnecessary FP_EXTEND. This causes worse codegen for SSE.Nate Begeman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22469 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-19For: memory operations -> storesReid Spencer
This is the first incremental patch to implement this feature. It adds no functionality to LLVM but setup up the information needed from targets in order to implement the optimization correctly. Each target needs to specify the maximum number of store operations for conversion of the llvm.memset, llvm.memcpy, and llvm.memmove intrinsics into a sequence of store operations. The limit needs to be chosen at the threshold of performance for such an optimization (generally smallish). The target also needs to specify whether the target can support unaligned stores for multi-byte store operations. This helps ensure the optimization doesn't generate code that will trap on an alignment errors. More patches to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22468 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-18The assertion was wrong: the code only worked for i64. While we're at it,Chris Lattner
expand the code to work for all integer datatypes. This should unbreak alpha. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22464 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-16Only get the .bss and .data sections when needed instead of unconditionally.Chris Lattner
This allows is to not emit empty sections when .data or .bss is not used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22457 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-16Refactor getSection() method to make it easier to use.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22455 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-16Major refactor of the ELFWriter code. Instead of building up one bigChris Lattner
vector that represents the .o file at once, build up a vector for each section of the .o file. This is needed because the .o file writer needs to be able to switch between sections as it emits them (e.g. switch between the .text section and the .rel section when emitting code). This patch has no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22453 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-16Teach the legalizer how to promote SINT_TO_FP to a wider SINT_TO_FP thatNate Begeman
the target natively supports. This eliminates some special-case code from the x86 backend and generates better code as well. For an i8 to f64 conversion, before & after: _x87 before: subl $2, %esp movb 6(%esp), %al movsbw %al, %ax movw %ax, (%esp) filds (%esp) addl $2, %esp ret _x87 after: subl $2, %esp movsbw 6(%esp), %ax movw %ax, (%esp) filds (%esp) addl $2, %esp ret _sse before: subl $12, %esp movb 16(%esp), %al movsbl %al, %eax cvtsi2sd %eax, %xmm0 addl $12, %esp ret _sse after: subl $12, %esp movsbl 16(%esp), %eax cvtsi2sd %eax, %xmm0 addl $12, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22452 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-16Break the code for expanding UINT_TO_FP operations out into its ownChris Lattner
SelectionDAGLegalize::ExpandLegalUINT_TO_FP method. Add a new method, PromoteLegalUINT_TO_FP, which allows targets to request that UINT_TO_FP operations be promoted to a larger input type. This is useful for targets that have some UINT_TO_FP or SINT_TO_FP operations but not all of them (like X86). The same should be done with SINT_TO_FP, but this patch does not do that yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22447 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-13Fix Alpha/2005-07-12-TwoMallocCalls.ll and PR593.Chris Lattner
It is not safe to call LegalizeOp on something that has already been legalized. Instead, just force another iteration of legalization. This could affect all platforms but X86, as this codepath is dynamically dead on X86 (ISD::MEMSET and friends are legal). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22419 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-11add code to emit the .text section to the section header.Chris Lattner
Add a *VERY INITIAL* machine code emitter class. This is enough to take this C function: int foo(int X) { return X +1; } and make objdump produce the following: $ objdump -d t-llvm.o t-llvm.o: file format elf32-i386 Disassembly of section .text: 00000000 <.text>: 0: b8 01 00 00 00 mov $0x1,%eax 5: 03 44 24 04 add 0x4(%esp,1),%eax 9: c3 ret Anything using branches or refering to the constant pool or requiring relocations will not work yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22375 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-10Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode.Chris Lattner

2005-07-10Introduce a new VTSDNode class with the ultimate goal of eliminating theChris Lattner
MVTSDNode class. This class is used to provide an operand to operators that require an extra type. We start by converting FP_ROUND_INREG and SIGN_EXTEND_INREG over to using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22364 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-05Make several cleanups to Andrews varargs change:Chris Lattner
1. Pass Value*'s into lowering methods so that the proper pointers can be added to load/stores from the valist 2.

Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22338 91177308-0d34-0410-b5e6-96231b3b80d8
