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

2005-07-18When transforming &A[i] < &A[j] -> i < j, make sure to perform the comparisonChris Lattner
as a signed compare. This patch may fix PR597, but is correct in any case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22465 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-17Add a parameter to the FIND_STD_PROGRAM macro that allows an alternate nameReid Spencer
for the command line options. This helps with situations where the executable name sought is too generic and a more meaningful name needs to be used for the command line options. It also helps satisfy picky project leaders. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22461 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-17Add two new checks for use in LLVM configuration files:Reid Spencer
* FIND_STD_PROGRAM will find a program in the path or using --with options and verify that the path/bin/program is executable. Also allows checking for include files and libraries. If found, USE_PROGRAM is set, otherwise its not set. Also sets PROGRAM_BIN (bin directory), and PROGRAM_DIR (top level directory). If headers are found, sets PROGRAM_INC. If libraries are found, sets PROGRAM_LIB. * CHECK_PROGRAM_SANITY can be used to run a program with some option that only produces information output and requires no input. If the output matches a regular expression, the program passes the sanity check. Otherwise, an error occurs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22458 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

2005-07-16Remove all knowledge of UINT_TO_FP from the X86 backend, relying on theChris Lattner
legalizer to eliminate them. With this comes the expected code quality improvements, such as, for this: double foo(unsigned short X) { return X; } we now generate this: _foo: subl $4, %esp movzwl 8(%esp), %eax movl %eax, (%esp) fildl (%esp) addl $4, %esp ret instead of this: _foo: subl $4, %esp movw 8(%esp), %ax movzwl %ax, %eax ;; Load not folded into this. movl %eax, (%esp) fildl (%esp) addl $4, %esp ret -Chris git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22449 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
