2011-01-07Rename lisp-like functions as suggested by Gabor Greif as loooong timeDavid Greene
ago. This is both easier to learn and easier to read. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123001 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-13Add support for using the `!if' operator when initializing variables:Bill Wendling
class A<bit a, bits<3> x, bits<3> y> { bits<3> z; let z = !if(a, x, y); } The variable z will get the value of x when 'a' is 1 and 'y' when a is '0'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121666 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-31fix the !eq operator in tblgen to return a bit instead of an int.Chris Lattner
Use this to make the X86 and ARM targets set isCodeGenOnly=1 automatically for their instructions that have Format=Pseudo, resolving a hack in tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117862 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-06Generalize tblgen's dag parsing logic to handle arbitrary expressionsChris Lattner
as the operator of the dag. Specifically, this allows parsing things like (F.x 4) in addition to just (a 4). Unfortunately, this runs afoul of an idiom being used by llvmc. It is using dags like (foo [1,2,3]) to represent a list of stuff being passed into foo. With this change, this is parsed as a [1,2,3] subscript on foo instead of being the first argument to the dag. Cope with this in the short term by requiring a "-llvmc-temp-hack" argument to tblgen to get the old parsing behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115742 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-18Teach tablegen how to inherit from classes in 'defm' definitions.Bruno Cardoso Lopes
The rule is simple: only inherit from a class list if they come in the end, after the last multiclass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106305 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-08Make IntInits and ListInits typed. This helps deduce types of !if andDavid Greene
other operators. For the rare cases where a list type cannot be deduced, provide a []<type> syntax, where <type> is the list element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73078 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.

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

2009-04-24Fix multiclass inheritance to limit value resolution to new defs addedDavid Greene
by base multiclasses. Do not attempt to alter defs from previous base multiclasses. This fixes multiple multiclass inheritance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69974 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Make BinOps typed and require a type specifier for !nameconcat. ThisDavid Greene

2009-03-19Add support to tablegen for naming the nodes themselves, not just the operands, Nate Begeman
in selectiondag patterns. This is required for the upcoming shuffle_vector rewrite, and as it turns out, cleans up a hack in the Alpha instruction info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67286 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-14Unbreak the build on win32.Cedric Venet
Cleanup some warning. Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync. Only tested with VS2008. hope it does not break anything. feel free to revert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64554 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
