| | | | | | | | | | | | | | | | that have not yet been defined. Removed used of grep and sed when parsing the results of "nm". This was originally motivated because if the user has specified options to grep using the environment variable GREP_OPTIONS this could break the script. Piping through grep/sed/sort/uniq is also (to my understanding) not necessary, and the equivalent operations can be done much faster in the Perl script. Using a crude benchmark, these changes resulted in a 3x speedup in the execution of GenLibDeps.pl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44372 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | working. I added the lexing files to the VStudio projects and removed the .l files from the VStudio projects. There was a problem with use of strtoll in TGLexer.cpp and Chris suggested switching to strtol, so that's included here. Additionally, this checkin adds minimal x64 builds to the VStudio builds. Build issues related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc are worked around, but not ultimately solved. Binaries used to be stored in ...\win32\{Debug|Release} but are now kept in ...\win32\bin\{win32|x64}\{Debug|Release} intermediate files will continue to be stored in the individual project directories under win32. Some names will likely change in the future to reflect that the vstudio projects are no longer 32-bit only, but I wanted to get things up and running today so kept away from bigger restructuring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44260 91177308-0d34-0410-b5e6-96231b3b80d8

* One mundane change: Change ReplaceAllUsesOfValueWith to *optionally* Chris Lattner2007-10-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | take a deleted nodes vector, instead of requiring it. One more significant change: Implement the start of a legalizer that just works on types. This legalizer is designed to run before the operation legalizer and ensure just that the input dag is transformed into an output dag whose operand and result types are all legal, even if the operations on those types are not. This design/impl has the following advantages: 1. When finished, this will *significantly* reduce the amount of code in LegalizeDAG.cpp. It will remove all the code related to promotion and expansion as well as splitting and scalarizing vectors. 2. The new code is very simple, idiomatic, and modular: unlike LegalizeDAG.cpp, it has no 3000 line long functions. :) 3. The implementation is completely iterative instead of recursive, good for hacking on large dags without blowing out your stack. 4. The implementation updates nodes in place when possible instead of deallocating and reallocating the entire graph that points to some mutated node. 5. The code nicely separates out handling of operations with invalid results from operations with invalid operands, making some cases simpler and easier to understand. 6. The new -debug-only=legalize-types option is very very handy :), allowing you to easily understand what legalize types is doing. This is not yet done. Until the ifdef added to SelectionDAGISel.cpp is enabled, this does nothing. However, this code is sufficient to legalize all of the code in 186.crafty, olden and freebench on an x86 machine. The biggest issues are: 1. Vectors aren't implemented at all yet 2. SoftFP is a mess, I need to talk to Evan about it. 3. No lowering to libcalls is implemented yet. 4. Various operations are missing etc. 5. There are FIXME's for stuff I hax0r'd out, like softfp. Hey, at least it is a step in the right direction :). If you'd like to help, just enable the #ifdef in SelectionDAGISel.cpp and compile code with it. If this explodes it will tell you what needs to be implemented. Help is certainly appreciated. Once this goes in, we can do three things: 1. Add a new pass of dag combine between the "type legalizer" and "operation legalizer" passes. This will let us catch some long-standing isel issues that we miss because operation legalization often obfuscates the dag with target-specific nodes. 2. We can rip out all of the type legalization code from LegalizeDAG.cpp, making it much smaller and simpler. When that happens we can then reimplement the core functionality left in it in a much more efficient and non-recursive way. 3. Once the whole legalizer is non-recursive, we can implement whole-function selectiondags maybe... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42981 91177308-0d34-0410-b5e6-96231b3b80d8
