Subject: [PATCH 1/3] [libclc] Move all remquo address spaces to CLC library

Previously the OpenCL address space overloads of remquo would call into
the one and only 'private' CLC remquo. This was an outlier compared with
the other pointer-argumented maths builtins.

This commit moves the definitions of all address space overloads to the
CLC library to give more control over each address space to CLC
implementers.

There are some minor changes to the generated bytecode but it's simply
moving IR instructions around.

[libclc] [libclc] Move all remquo address spaces to CLC library (PR #140871)

2025-05-21 Thread Fraser Cormack via cfe-commits 

https://github.com/frasercrmck created

Previously the OpenCL address space overloads of remquo would call into the one 
and only 'private' CLC remquo. This was an outlier compared with the other 
pointer-argumented maths builtins.

This commit moves the definitions of all address space overloads to the CLC 
library to give more control over each address space to CLC implementers.

There are some minor changes to the generated bytecode but it's simply moving 
IR instructions around.
