Antoine Pitrou commented on ARROW-3701:
---------------------------------------
LLVM IR is generally not cross-platform, as it will encode platform
specificities such as type widths, ABI, etc.
(see LLVM FAQ at
[https://llvm.org/docs/FAQ.html#can-i-compile-c-or-c-code-to-platform-independent-llvm-bitcode])
Perhaps by being extra-careful it's possible to have IR generated for one
platform compile and interface correctly on another platform, but it sounds a
bit fragile.
> [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
