Antoine Pitrou commented on ARROW-3701:
---------------------------------------
> Is this documented somewhere?
I don't know. That was the result of testing some years ago. That said, it
seems better supported nowadays. If you take the following IR:
{code}
define i128 @increment(i128 %a) {
%result = add i128 %a, 1
ret i128 %result
}
define i128 @square(i128 %a) {
%result = mul i128 %a, %a
ret i128 %result
}
define i128 @divide(i128 %a, i128 %b) {
%result = udiv i128 %a, %b
ret i128 %result
}
{code}
Then compiling it seems to work fine for several targets I tried it with:
{code}
llc-6.0 -O3 -march=x86-64 testfile.ir
{code}
> [Gandiva] Add support for decimal operations
> --------------------------------------------
>
> Key: ARROW-3701
> URL: https://issues.apache.org/jira/browse/ARROW-3701
> Project: Apache Arrow
> Issue Type: Task
> Components: Gandiva
> Reporter: Pindikura Ravindra
> Assignee: Pindikura Ravindra
> Priority: Major
>
> To begin with, will add support for 128-bit decimals. There are two parts :
> # llvm_generator needs to understand decimal types (value, precision, scale)
> # code decimal operations : add/subtract/multiply/divide/mod/..
> ** This will be c++ code that can be pre-compiled to emit IR code
