Accessing TableGen defined variable in the cpp code
...e class in TableGen:
*bits<4> bitpattern = 0;*
*let Inst{10-7} = bitpattern;*
Then, at the moment that I am parsing the instruction, I would like to
assign a value to "bitpattern" variable!
for example:
->ParseInstruction(...)
if (Mnemonic == "X")
Mnemonic = getLexer().getTok().getString();
if (Mnemonic == "Y")
*** let bitpattern = 0b1010" ** // How can I do this?*
How can I do this? Is it possible?
Cheers,
ES

Parse Instruction
....
I would like to parse an assembly code that is space-separated and I am
having a bit of problem.
In *ParseInstruction* function, I don't know what is the easiest way to
figure out how many operands a mnemonic expected to have.
In comma-separated assembly code, it just consuming commas (while
(getLexer().is(AsmToken::Comma))) and adds operands, but it's not the case
for space...
I have a dirty hack, that I manually provide such information (number of
operands) in a function called for example getMnemonicAcceptInfo and with a
for loop I parse the operand!!
What would you suggest for parsing...
