Subject: [PATCH] gallivm/nir: fix const loading on big endian systems
|
|
|
46a384 |
|
|
|
46a384 |
The code was expecting the lower 32-bits of the 64-bit to be
|
|
|
46a384 |
what it wanted, don't be implicit, pull the value from the union.
|
|
|
46a384 |
|
|
|
46a384 |
This should fix rendering on big endian systems since NIR was
|
|
|
46a384 |
introduced.
|
|
|

|

Fixes: 44a6b0107b37 ("gallivm: add nir->llvm translation (v2)")
