Bug ID: 106163
Summary: r600/sb: optimizer tries to schedule access to
different array elements in one intstruction group
Product: Mesa
Version: git
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: low
Component: Drivers/Gallium/r600

piglit test that triggers the faulty behaviour
The attached piglit test will run through in release mode, because sb bails out
in the post_scheduler:
##post_scheduler: unscheduled pending instructions :MOV R6.x.1F,
0.5|3f000000
MOV R5.x.1F, 0|00000000
MOV R3.x.1F, 1|3f800000
sb: error (1) in the post_scheduler pass.
sb: using unoptimized bytecode...
Obviously it would be preferable if sb would generate proper code instead.
Also in debug mode an assertion will fail at this point.
It is another incarnation of #103142, but I think it is better to open this as
a new bug.
