* nv50/ir/ra: Fix live set propagation in the secondary passes of buildLiveSets().Francisco Jerez2012-04-141-3/+3
|
* nv50/ir/opt: don't regard OP_WRSV as dead codeChristoph Bumiller2012-04-141-1/+2
|
* nv50/ir: add isUniform query to ValuesChristoph Bumiller2012-04-142-0/+24
|
* nv50/ir: rewrite the register allocator as GCRA, with spillingChristoph Bumiller2012-04-1411-418/+1475
| | | | | This is more flexible than the linear scan, and we don't need the separate allocation pass for constrained values anymore.
* nv50/ir/tgsi: only export x-component of PSIZEChristoph Bumiller2012-04-141-1/+5
|
* nvc0: fix emission of 3rd src in SET_AND,OR,XORChristoph Bumiller2012-04-141-0/+3
|
* nv50/ir: Fix BuildUtil::mkSelect and mkClobberFrancisco Jerez2012-04-141-6/+2
|
* nv50/ir: fix reg file conflicts with undefined-value placeholdersChristoph Bumiller2012-04-141-10/+19
|
* nv50/ir/opt: silence warning (int < Elements() signedness)Christoph Bumiller2012-04-141-1/+1
|
* nv50/ir/opt: fix combineSt access to wrong instructionChristoph Bumiller2012-04-141-1/+1
|
* nv50/ir/opt: another insn NULL check in phi eliminationChristoph Bumiller2012-04-141-0/+2
|
* nv50/ir/ssa: Take into account function inputs and outputs.Francisco Jerez2012-04-141-2/+30
|
* nv50/ir: Clean up before calculating instruction ordering for a new function.Francisco Jerez2012-04-142-0/+16
|
* nv50/ir/ra: Allocate registers for function arguments.Francisco Jerez2012-04-141-0/+6
|
* nv50/ir: Take into account function args in the live range calculation code.Francisco Jerez2012-04-142-3/+28
|
* nv50/ir/ra: Use matching physical regs for function args in caller and callee.Francisco Jerez2012-04-141-6/+83
|
* nv50/ir/tgsi: Infer function inputs/outputs.Francisco Jerez2012-04-142-0/+87
| | | | | | | Edit: Don't do it for the main function of (graphics) shaders, its inputs and outputs always go through TGSI_FILE_INPUT/OUTPUT. This prevents all TEMPs from counting as live out and reduces register pressure.
* nv50/ir/tgsi: Replace the inlining logic with proper function calls.Francisco Jerez2012-04-145-68/+82
|
* nv50/ir: Decouple DataArray from the dictionary that maps locations to values.Francisco Jerez2012-04-144-223/+236
| | | | | | | | | | | The point is to keep an independent dictionary for each function. The array that was being used as dictionary has been converted into a "bimap" for two different reasons: first, because having an almost empty instance of an array with as many entries as registers there are in the program, once for every function, would be wasteful, and second, because we want to be able to map Value pointers back to locations at some point.
* nv50/ir/opt: don't delete instruction in removeFlow before its last useChristoph Bumiller2012-04-141-2/+2
|
* nv50/ir/opt: check BB equality before instruction ordering in CSEChristoph Bumiller2012-04-141-1/+1
|
* nv50/ir/opt: don't copy-propagate cond MOVs or MOVs to other reg filesChristoph Bumiller2012-04-141-0/+4
| | | | | We've never encountered the latter on nvc0, but on nv50 we have moves between GPRs and address regs.
* nv50/ir/opt: don't replace conditional definitions in CSEChristoph Bumiller2012-04-142-0/+10
|
* nv50/ir/opt: Update the symbol size when combining loads and stores.Francisco Jerez2012-04-141-0/+2
|
* nv50/ir: initialize FlowInstruction::builtinChristoph Bumiller2012-04-141-1/+1
|
* nv50/ir/opt: Fix for function calls.Francisco Jerez2012-04-141-2/+3
|
* nv50/ir: Build a "symbol" table with the binary offsets of each function.Francisco Jerez2012-04-147-5/+45
|
* nv50/ir: Add support for removing functions from a program.Francisco Jerez2012-04-142-0/+3
|
* nv50/ir: Scan program functions in DFS-postorder.Francisco Jerez2012-04-145-7/+16
| | | | | | The reason is that several passes (regalloc, function argument binding, inlining) are going to require the callees of a function to be processed before the caller.
* nv50/ir: Deal with graph iterators using RAII.Francisco Jerez2012-04-146-70/+43
|
* nv50/ir: Add convenience method for calculating the live sets of a function.Francisco Jerez2012-04-143-7/+12

|
* nv50/ir: Add support for cloning FlowInsns, ImmediateVals and BBs.Francisco Jerez2012-04-143-0/+66
|
* nv50/ir: Decouple object cloning logic from the sub-object recursion policy.Francisco Jerez2012-04-147-68/+181
|
* nv50/ir: Make sure that several IR objects are destroyed on takedown.Francisco Jerez2012-04-143-3/+17
|
* nv50/ir: make Instruction::src/def container privateChristoph Bumiller2012-04-1411-304/+320
|
* nv50/ir: Add support for unlimited instruction arguments.Francisco Jerez2012-04-147-211/+141
|
* nv50/ir: temporarily exclude nv50 code emitter from buildChristoph Bumiller2012-04-141-1/+0
| | | | | It's not used yet and shouldn't have been included in the first place.
* nv50/ir: copy value size in SSA-rename passChristoph Bumiller2012-04-141-0/+1
|
* nv50/ir/opt: improve post-multiply and check target for supportChristoph Bumiller2012-04-144-35/+90
|
* nv50/ir: add setFlagsDef/Src helperChristoph Bumiller2012-04-144-3/+29
| | | | Will be used by nv50 target.
* nv50/ir: add isAccessSupported check for memory access coalescingChristoph Bumiller2012-04-146-5/+19
|
* nv50/ir: add function for splitting a BasicBlockChristoph Bumiller2012-04-143-9/+78
| | | | Fixes to initial implementation by Francisco Jerez.
* nv50/ir: Allow attaching two nodes when either one is already inside the graph.Francisco Jerez2012-04-141-5/+5
|
* nv50/ir: Allow inserting isolated nodes to a graph.Francisco Jerez2012-04-141-6/+4
|
* nv50/ir: Fix memory corruption in Function::orderInstructions().Francisco Jerez2012-04-141-3/+7
| | | | | "iter" doesn't reference a BasicBlock directly, but a Node::Graph, i.e. BasicBlock::get() is casting to the wrong pointer type.
* nv50/ir: Fix up insertion of PHI instructions using bb->insertHead().Francisco Jerez2012-04-141-1/+1
|
* nv50/ir: fix insertHead and remove for BBs with PHI ops onlyChristoph Bumiller2012-04-141-3/+10
