| | | | | | | | | | This commit fixes a bug in register coalesce that happens when one register is moved to another the proper number of times but the channels are re-arranged. When this happens, the previous code would happily coalesce the registers regardless of the fact that the channel mappins were wrong.

* i965/fs: Rework GEN5 texturing code to use fs_reg and offset()Jason Ekstrand2014-09-301-39/+38
| | | | | | | | | | | | Now that offset() can properly handle MRF registers, we can use an MRF fs_reg and let offset() handle incrementing it correctly for different dispatch widths. While this doesn't have any noticeable effect currently, it does ensure that the destination register is 16-wide which will be necessary later when we start detecting execution sizes based on source and destination registers.

* i965/fs_reg: Allocate double the number of vgrfs in SIMD16 modeJason Ekstrand2014-09-309-157/+371
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is actually the squash of a bunch of different changes. Individual commit titles follow: i965/fs: Always 2-align registers SIMD16 for gen <= 5 i965/fs: Use the register width when applying offsets This reworks both byte_offset() and offset() to be more intelligent. The byte_offset() function now supports offsets bigger than 32. The offset() function uses the byte_offset() function together with the register width and the type size to offset the register by the correct amount. i965/fs: Change regs_read to be in hardware registers i965/fs: Change regs_written to be actual hardware registers i965/fs: Properly handle register widths in LOAD_PAYLOAD The LOAD_PAYLOAD instruction is a bit special because it collects a bunch of registers (with possibly different widths) into a single payload block. Once the payload is constructed, it's treated as a single block of data and most of the information such as register widths doesn't matter anymore. In particular, the offset of any particular source register is the accumulation of the sizes of the previous source registers. i965/fs: Properly set writemasks in LOAD_PAYLOAD i965/fs: Handle register widths in demote_pull_constants i965/fs: Get rid of implicit register doubling in the allocator i965/fs: Reserve enough registers for PLN instructions i965/fs: Make sources and destinations interfere in 16-wide i965/fs: Properly handle register widths in CSE i965/fs: Properly handle register widths in register_coalesce i965/fs: Properly handle widths in copy propagation i965/fs: Properly handle register widths in VARYING_PULL_CONSTANT_LOAD i965/fs: Properly handle register widths and odd register sizes in spilling i965/fs: Don't waste a register on texture lookups for gen >= 7 Previously, we were waisting a register in SIMD16 mode because we could only allocate registers in pairs. Now that we can allocate and address odd-sized registers, let's get rid of this special-case. Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Matt Turner <[email protected]>

* i965/fs: Add a concept of a width to fs_regJason Ekstrand2014-09-302-4/+78
| | | | | | | | | | | | | | | | | | | | Every register in i965 assembly implicitly has a concept of a "width". Usually, this is derived from the execution size of the instruction. However, when writing a compiler it turns out that it is frequently a useful to have the width explicitly in the register and derive the execution size of the instruction from the widths of the registers used in it. This commit adds a width field to fs_reg along with an effective_width() helper function. The effective_width() function tells you how wide the register effectively is when used in an instruction. For example, uniform values have width 1 since the data is not actually repeated, but when used in an instruction they take on the width of the instruction. However, for some instructions (LOAD_PAYLOAD being the notable exception), the width is not the same. Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Matt Turner <[email protected]>

* i965/fs: Copy propagate partial reads.Jason Ekstrand2014-09-302-20/+64
| | | | | | | | | | | | | | | | | | This commit reworks copy propagation a bit to support propagating the copying of partial registers. This comes up every time we have pull constants because we do a pull constant read immediately followed by a move to splat the one component of the out to 8 or 16-wide. This allows us to eliminate the copy and simply use the one component of the register.

| | | | | | | | | | | | | | Previously we disabled compact_virtual_grfs when dumping optimizations. The idea here was to make it easier to diff the dumped shader because you didn't have a sudden renaming. However, sometimes a bug is affected by compact_virtual_grfs and, when this happens, you want to keep dumping instructions with compact_virtual_grfs enabled. By turning it into an optimization pass and dumping it along with the others, we retain the ability to diff because you can just diff against the compact_virtual_grf output.

| | | | | | | | | | | | Previously, if an instruction wrote to more than one register, we implicitly assumed that it filled the entire register. We never hit this before because the only time we did multi-register writes was things like texturing which always wrote to all of the registers. However, with the upcoming ability to do 16-wide instructions in SIMD8 and things of that nature, we can have multi-register writes at offsets and we'll hit this.

| | | | | | | | | | | | | | The original vgrf splitting code was written with the assumption that vgrfs came in two types: those that can be split into single registers and those that can't be split at all It was very conservative and bailed as soon as more than one element of a register was read or written. This won't work once we start allowing a regular MOV or ADD operation to operate on multiple registers. This rewrite allows for the case where a vgrf of size 5 may appropriately be split in to one register of size 1 and two registers of size 2.

* i965/fs: Manually generate the meta fast-clear shaderJason Ekstrand2014-09-302-90/+35
| | | | | | | | | | | | | | | | | | Previously, we were generating the fast-clear shader from GLSL. The problem is that fast clears require that we use a replicated write rather than a regular write instruction. In order to get this we had a complicated and somewhat fragile optimization pass that looked for places where we can use a replicated write and used it. Since replicated writes have a lot of restrictions, we only ever use them for fast-clear operations. This commit replaces the optimization pass with a function that just generates the shader we want. This is a) less code, b) less fragile than the optimization pass, and c) generates a more efficient shader.
