TBLGEN(1) LLVM Command Guide TBLGEN(1)NAME
tblgen - Target Description To C++ Code Generator
SYNOPSIS
tblgen [options] [filename]
DESCRIPTION
tblgen translates from target description (.td) files into C++ code that can be included in the definition of an LLVM target library. Most
users of LLVM will not need to use this program. It is only for assisting with writing an LLVM target backend.
The input and output of tblgen is beyond the scope of this short introduction. Please see the CodeGeneration page in the LLVM
documentation.
The filename argument specifies the name of a Target Description (.td) file to read as input.
OPTIONS -help
Print a summary of command line options.
-o filename
Specify the output file name. If filename is "-", then tblgen sends its output to standard output.
-I directory
Specify where to find other target description files for inclusion. The directory value should be a full or partial path to a directory
that contains target description files.
-asmwriternum N
Make -gen-asm-writer emit assembly writer number N.
-class class Name
Print the enumeration list for this class.
-print-records
Print all records to standard output (default).
-print-enums
Print enumeration values for a class
-gen-emitter
Generate machine code emitter.
-gen-register-enums
Generate the enumeration values for all registers.
-gen-register-desc
Generate a register info description for each register.
-gen-register-desc-header
Generate a register info description header for each register.
-gen-instr-enums
Generate enumeration values for instructions.
-gen-instr-desc
Generate instruction descriptions.
-gen-asm-writer
Generate the assembly writer.
-gen-dag-isel
Generate a DAG (Directed Acycle Graph) instruction selector.
-gen-subtarget
Generate subtarget enumerations.
-gen-intrinsic
Generate intrinsic information.
-version
Show the version number of this program.
EXIT STATUS
If tblgen succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.

dds - double dummy solver frontend
SYNOPSIS
dds file [ options ]
DESCRIPTION
This program is a command line interface for Bo Haglund's Double Dummy Solver (DDS).
It has four useful stand-alone options:
1. Option -playdd, to play any deal double dummy.
2. Option -giblib. For any deal, to get maximum trick values for all possible contracts and leaders (these are the 20 trick values as
for giblib).
3. Option -tricks. For specified deal, to get maximum trick values for all possible contracts and leaders (these are the 20 trick val-
ues as for giblib).
4. Option -gen. This is to generate deals, without or with up to 20 possible trick values.
OPTIONS
file path for 'giblib' input file
Optional arguments [options] are one or more of:
-v verbose where applicable
-target=d
-1-13 (default -1). Number of tricks to be won by the side to play, -1 means that the program shall find the maximum number. For
equivalent cards only the highest is returned.
-sol=d solution 1/2/3 (default 3). How many card solutions SolveBoard returns:
target=1-13, solutions=1: Returns only one of the cards. Its returned score is the same as target when target or higher tricks can
be won. Otherwise, score -1 is returned if target cannot be reached, or score 0 if no tricks can be won.
target=-1, solutions=1: Returns only one of the optimum cards and its score.
target=0, solutions=1: Returns only one of the cards legal to play with score set to 0.
target=1-13, solutions=2: Return all cards meeting target. Their returned scores are the same as target when target or higher
tricks can be won. Otherwise, only one card is returned with score -1 if target cannot be reached, or score 0 for all cards legal
to play if no tricks can be won.
target=-1, solutions=2: Return all optimum cards with their scores.
target=0, solutions=2: Return all cards legal to play with scores set to 0.
target irrelevant, solutions=3: Return all cards that can be legally played with their scores in descending order.
-mode=d
0/1 (default 1). DLL mode of operation. This mode does not affect the DLL if there are multiple choices for cards to play. If there
is just one card to play, or multiple cards that are all equivalent, this mode determines whether or not the DLL will search to
find the score.
mode=0: Do not search to find the score if the hand to play has only one card, including its equivalents, to play. Score is set to
-2 for this card, indicating that there are no alternative cards. This mode is very fast.
mode=1: Always search to find the score. Even when the hand to play has only one card, with possible equivalents, to play.
-trumps=t
s/h/d/c/n, this overrides the file (default=n)
-leader=l
w/n/e/s, this overrides the file (default=w) but used only when no cards have been played
-deal=d
1/2/... deal number in giblib file. Only one of -deal or -name should be specified.
-name=str
deal with 'name=str' in giblib file. Only one of -deal or -name should be specified.
-playdd
play deal choosing between DDS alternatives
-timeall
time all deals in file for sol=1/2/3, print stats
-timeg=xcn
x - hex digit, total tricks by n-s
c - contract s/h/d/c/n
n - number of deals
time the first n deals in the giblib file, having total tricks x at contract c, for target=-1 sol=1 mode=1 and for the speci-
fied/default leader, each deal is validated.
-giblib=d1-d2[-all]
validate all deals from d1 to d2 in giblib file for target=-1 sol=1 mode=1. 1. if -all is given, this is done for all of the 20
trick values even if some of them are '-'. 2. if -all is not given, this is done only for those trick values which are not '-'.
-tricks
like -giblib, but for single deal specified by -name=str -deal=d or option
Generate deals:
-gen=n (required) n=number of deals to generate. output is written to a file (see below)
-genseed=s
(default 0) seed for random generator
-gencards=c
(default=52) number of cards generated per deal, must be multiple of 4
-gentricks=t
0,1,...,20 (default 1), number of tricks values to set randomly
Generate output is written to a file:
gen-genseed-ndeal-gencards-gentricks.txt
NOTES
The program was named ddd by its author. As there is already some other ddd package in Debian (the gdb frontend) it was renamed to dds, the
name of the library used.
