| | | | | | | | | | | | | generator. Currently the generator code for most opcodes honours the default access mode (which should typically be Align1 in the scalar back-end), but generate_code() doesn't set it explicitly which means that the access mode from a previous instruction could leak into the following ones if you did something special and weren't careful enough to save and restore the previous access mode.

* i965/fs: Remove handcrafted math SIMD lowering from the generator.Francisco Jerez2016-05-272-101/+21
| | | | | | | | Most of this wouldn't have worked for SIMD32 and had various dispatch_width and compression control bugs. It's mostly dead now with SIMD lowering of math instructions turned on in the compiler. Reviewed-by: Jason Ekstrand <[email protected]>

* i965/fs: Lower LOAD_PAYLOAD instructions of unsupported width.Francisco Jerez2016-05-271-0/+19
| | | | | | | | | | | | | | | | Only per-channel LOAD_PAYLOAD instructions can be lowered, which should cover everything that comes in from the front-end. LOAD_PAYLOAD instructions used to construct actual message payloads cannot be easily lowered because they contain headers and vectors of variable type that aren't necessarily channel-aligned -- We shouldn't find any of them in the program at SIMD lowering time though because they're introduced during logical send lowering. An alternative that may be worth considering would be to re-run the SIMD lowering pass after LOAD_PAYLOAD lowering instead of this patch. Reviewed-by: Jason Ekstrand <[email protected]>

* i965/fs: Enforce common regioning restrictions by SIMD splitting.Francisco Jerez2016-05-271-20/+104
| | | | | | | | | | | | | | | | | This change addresses a number of hardware restrictions on the source and destination regions and other execution controls of regular FPU-like instructions that in some cases can be avoided by reducing the execution size of the instruction. Some of these restrictions (e.g. the one about 3src instructions not supporting compression on some hardware) are currently being worked around case by case in the generator with ad-hoc splitting code that is buggy in several ways (e.g. doesn't handle non-trivial execution controls which would break SIMD32 code), but it seems cleaner to implement as many restrictions as we can in a single lowering pass since that will allow us to simplify some of the surrounding code considerably and also make sure that we don't forget applying them in the future.

* i965/fs: Enforce extended math exec size limits during SIMD lowering.Francisco Jerez2016-05-271-10/+24
| | | | | | | | | | This teaches the SIMD lowering pass about the hardware limits on the execution size of math instructions, which will allow simplifying the generator code and at the same time get rid of a number of bugs in the manual SIMD unrolling done currently that prevent SIMD32 codegen from working.

* i965/fs: Handle SAMPLEINFO consistently like other texturing instructions.Francisco Jerez2016-05-274-17/+15
| | | | | | | | | | | Seems like this texturing opcode was missing its logical counterpart which would prevent it from taking advantage of the SIMD lowering infrastructure, define it and plumb it through the back-end. At some point we'll likely want to emit a single SAMPLEINFO message shared among all channels irrespective of this change, but for the moment this should be enough to get the intrinsic working in SIMD32 mode.

| | | | | | | | | Varying pull constant loads inherit the same limitation of pre-ILK hardware that requires expanding SIMD8 texel fetch instructions to SIMD16, we can deal with pull constant loads in the same way it's done for texturing during SIMD lowering.

* i965/fs: Avoid constant propagation when the type sizes don't match.Francisco Jerez2016-05-271-0/+8
| | | | | | | | | | | | The case where the source type of the instruction is smaller than the immediate type could be handled by calculating the portion of the immediate read by the instruction (assuming that the source channels are aligned with the destination channels of the copy) and then representing the same value as an immediate of the source type (assuming such an immediate type exists), but the code below doesn't do that, so just bail for the moment.

* i965/fs: Fix CSE temporary copy for some LOAD_PAYLOAD corner cases.Francisco Jerez2016-05-271-1/+2
| | | | | | | | | | | | | If the LOAD_PAYLOAD instruction only has header sources it's possible for the number of registers written to be less than or equal to the SIMD component size, in which case it would take the single-MOV path at the bottom which would cause the channel enable masks to be applied incorrectly to the header contents and/or cause it to write past the end of the allocated temporary. If the instruction is either LOAD_PAYLOAD or doesn't write exactly one component the MOV path is going to mess up the program so just don't use it. Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | If the source value is going to the same for all SIMD-lowered chunks of the instruction there should be no need to unzip the value into multiple temporary registers one for each lowered chunk. As a side effect this fixes SIMD lowering of instructions with a vector immediate source. In the long term it *might* still be worth fixing offset() to handle vector immediates correctly though, this should be good enough for the moment. Reviewed-by: Jason Ekstrand <[email protected]>

* i965/fs: Fix off-by-one region overlap comparison in copy propagation.Francisco Jerez2016-05-271-2/+2
| | | | | | | | | | | | | | This was introduced in cf375a3333e54a01462f192202d609436e5fbec8 but the blame is mine because the pseudocode I sent in my review comment for the original patch suggesting to do things this way already had the off-by-one error. This may have caused copy propagation to be unnecessarily strict while checking whether VGRF writes interfere with any ACP entries and possibly miss valid optimization opportunities in cases where multiple copy instructions write sequential locations of the same VGRF.
