2010-01-05Add an !eq() operator to TableGen. It operates on strings only.David Greene
Use !cast<string>() to compare other types of objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92754 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-09Revert 73074 and 73099 because Windows doesn't have POSIXDavid Greene
regular expressions. We will add an OpenBSD implementation and re-apply ASAP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73138 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08Add a !patsubst operator. Use on string types.David Greene
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73099 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71815 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-14Graduate LLVM to the big leagues by embedding a LISP processor into TableGen.David Greene
Ok, not really, but do support some common LISP functions: * car * cdr * null git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71805 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-14Implement a !foreach operator analogous to GNU make's $(foreach).David Greene
Use it on dags and lists like this: class decls { string name; } def Decls : decls; class B<list<string> names> : A<!foreach(Decls.name, names, !strconcat(Decls.name, ", Sr."))>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71803 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-14Implement a !subst operation simmilar to $(subst) in GNU make to doDavid Greene
def/var/string substitution on generic pattern templates. For example: def Type; def v4f32 : Type; def TYPE : Type; class GenType<Type t> { let type = !(subst TYPE, v4f32, t); } def TheType : GenType<TYPE>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71801 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-14Implement !cast.David Greene
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71794 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-14Operation EnhancementsDavid Greene
Create an OpInit class to serve as a base for all operation Inits. Move parsing of operation constructs to separate functions and reference from multiple places. Add some commented out new operations. Coming soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71789 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-05Allow multiclass def names to contain "#NAME"" where TableGen replacesDavid Greene
#NAME# with the name of the defm instantiating the multiclass. This is useful for AVX instruction naming where a "V" prefix is standard throughout the ISA. For example: multiclass SSE_AVX_Inst<...> { def SS : Instr<...>; def SD : Instr<...>; def PS : Instr<...>; def PD : Instr<...>; def V#NAME#SS : Instr<...>; def V#NAME#SD : Instr<...>; def V#NAME#PS : Instr<...>; def V#NAME#PD : Instr<...>; } defm ADD : SSE_AVX_Inst<...>; Results in ADDSS ADDSD ADDPS ADDPD VADDSS VADDSD VADDPS VADDPD git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70979 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Implement !nameconcat to concatenate strings and look up the resultingDavid Greene
name in the symbol table, returning an object. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69822 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13Fix escaping in asm string literals correctly by having tblgen unescape Chris Lattner
them, then the asmprinter emitter reescape them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66958 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13add a horrible hack to fix the build.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66957 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13add support for a few simple escape characters in tblgen strings.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66949 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13make "locations" a class instead of a typedef.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66895 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13split buffer management and diagnostic printing out of the tblgenChris Lattner
lexer into its own TGSourceMgr class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66873 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-17Fun x86 encoding tricks: when adding an immediate value of 128,Dan Gohman
use a SUB instruction instead of an ADD, because -128 can be encoded in an 8-bit signed immediate field, while +128 can't be. This avoids the need for a 32-bit immediate field in this case. A similar optimization applies to 64-bit adds with 0x80000000, with the 32-bit signed immediate field. To support this, teach tablegen how to handle 64-bit constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57663 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-08Add <cstdio> include where needed by gcc-4.4.Duncan Sands
Patch by Samuel Tardieu. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57291 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner
start of a filename, not a filename+length. All clients can produce a null terminated name, and the system api's require null terminated strings anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49041 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-20Unbreak build with gcc 4.3: provide missed includes and silence most ↵Anton Korobeynikov
annoying warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47367 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29remove attributions from utils.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45419 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-22Rewrite the tblgen parser in a recursive descent style, eliminating the ↵Chris Lattner
bison parser. This makes the parser much easier to understand, eliminates a ton of global variables, and gives tblgen nice caret diagnostics. It is also faster, but tblgen probably doesn't care about performance. There are a couple of FIXMEs which I will take care of next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44274 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-21Switching back to strtoll. Including config.h. On VStudio builds, this ↵Chuck Rose III
overrides strtoll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44264 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-21This change does a couple of things. First it gets the Visual Studio builds ↵Chuck Rose III
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

2007-11-19Add carat diagnostics to tblgen lexer errors.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44226 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-18reimplement the tblgen lexer with a simple hand-written lexer. This eliminatesChris Lattner
one dependency on flex and gets rid of two ".cvs" files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44210 91177308-0d34-0410-b5e6-96231b3b80d8
