[LLVMdev] TableGen and computed expressions
...ed value instead of a constant?
For example, with the latency issues, the old instruction might have a
latency of 2 - expressed as the constant '2' - while the value for the
revised instruction is '3'. I would like to be able to provide this value
using a function call ( e.g. 'getLatency()'), or some other externally
computed value.
For the mnemonics I was wondering if it is possible to provide a fragment to
'strconcat' from a function call, or perhaps from an array with an index
(e.g. 'AsmFrag[VALUE]')?
I have tried variants of '[{ code }]' but th...

[LLVMdev] Question on Machine Combiner Pass
...d latency for the current
instruction (MUL+ADD) and the alternate instruction (MADD).
But we call two different set of APIs for the current and new instructions:
For new instruction we use:
unsigned NewRootDepth = getDepth(InsInstrs, InstrIdxForVirtReg, BlockTrace);
unsigned NewRootLatency = getLatency(Root, NewRoot, BlockTrace);
While for the current instruction we use:
unsigned RootDepth = BlockTrace.getInstrCycles(Root).Depth;
unsigned RootLatency = TSchedModel.computeInstrLatency(Root);
This is related to the following commit:

Looking at this more carefully, I think that I see the problem. The
heights are set to account for the latencies:
PredSU->setHeightToAtLeast(SU->getHeight() + PredEdge->getLatency());
but the latencies are considered only if the node as an ILP scheduling
preference (the default in TargetLowering.h is None):
bool LStall = (!checkPref || left->SchedulingPref == Sched::ILP) &&
BUHasStall(left, LHeight, SPQ);

[PATCH mesa 1/6] tgsi_build: Fix return of uninitialized memory in tgsi_*_instruction_memory
tgsi_default_instruction_memory / tgsi_build_instruction_memory were
returning uninitialized memory for tgsi_instruction_memory.Texture and
tgsi_instruction_memory.Format. Note 0 means not set, and thus is a
correct default initializer for these.
Fixes: 3243b6fc97 ("tgsi: add Texture and Format to tgsi_instruction_memory")
