Subject: [PATCH v3 0/3] Hexagon (target/hexagon) Only pass env to generated helper when needed
Date: Tue, 13 Feb 2024 21:27:23 -0700 [thread overview]
Message-ID: <20240214042726.19290-1-ltaylorsimpson@gmail.com> (raw)
Currently, we pass env to every generated helper. When the semantics of
the instruction only depend on the arguments, this is unnecessary and
adds extra overhead to the helper call.
**** Changes in v3 ****
Update copyright year to 2024
Mark Reviewed-by/Tested-by: Anton Johansson <anjo@rev.ng>
**** Changes in v2 ****
- Separate patches to pass P0 and SP explicitly to helpers that need it
- Add the TCG_CALL_NO_RWG_SE flag to any non-HVX helpers that
don't get ptr to env
Taylor Simpson (3):
Hexagon (target/hexagon) Pass P0 explicitly to helpers that need it
Hexagon (target/hexagon) Pass SP explicitly to helpers that need it
