Bug ID: 90348
Summary: Spilling failure of b96 merged value
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Reporter: imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org
QA Contact: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Sometimes the spilling logic will decide to spill a merged def. This is fine
for 2- and 4-wide values as there are appropriate load/store instructions for
those, but not so with 3-wide values. We must take that into account in the
SpillCodeInserter and emit a 64-bit and 32-bit store into lmem (and similar for
load, although less important, as it tends to have gotten split up by the time
the use rolls around).
Unfortunately I've lost track of the program that repro'd this issue.

And ideally it'd be smart enough to go for a 64 + 32 store rather than 3x 32, but that's probably too much -- split then re-merge. (Or can split take unevenly sized defs? That seems like asking for trouble.) -- You are receiving this mail because: You are the QA Contact for the bug. You are the assignee for the bug.
