Steven Perron	0e1b7e5aef	Fix getting operand without checking opcode. Fixes https://github.com/KhronosGhttps://github.com/KhronosGroup/SPIRV-Tools/issues/1559roup/SPIRV-Tools/issues/1559. There is an load of an operand of an instruction that was suppose to be only for the OpCompositeExtract case. However, an error caused it to be loaded for every opcode, even those that do not have an operand in that position. We fix up that bug, and a couple other things noticed that the same time.	2018-05-16 09:34:43 -04:00
Steven Perron	af430ec822	Add pass to fold a load feeding an extract. We have already disabled common uniform elimination because it created sequences of loads an entire uniform object, then we extract just a single element. This caused problems in some drivers, and is just generally slow because it loads more memory than needed. However, there are other way to get into this situation, so I've added a pass that looks specifically for this pattern and removes it when only a portion of the load is used. Fixes #1547.	2018-05-14 15:40:34 -04:00

Fix getting operand without checking opcode.

Fixes https://github.com/KhronosGhttps://github.com/KhronosGroup/SPIRV-Tools/issues/1559roup/SPIRV-Tools/issues/1559.

There is an load of an operand of an instruction that was suppose to be
only for the OpCompositeExtract case.  However, an error caused it to
be loaded for every opcode, even those that do not have an operand in
that position.

We fix up that bug, and a couple other things noticed that the same
time.

We have already disabled common uniform elimination because it created
sequences of loads an entire uniform object, then we extract just a
single element.  This caused problems in some drivers, and is just
generally slow because it loads more memory than needed.

However, there are other way to get into this situation, so I've added
a pass that looks specifically for this pattern and removes it when only
a portion of the load is used.

Fixes #1547.
