How to constraint instructions reordering from patterns?
Here is a last example to illustrate my concern.
The problem is about the lowering of node t13.
Initial selection DAG: BB#0 '_start:entry'
SelectionDAG has 44 nodes:
t11: i16 = Constant<0>
t0: ch = EntryToken
t3: ch = llvm.clp.set.rspa t0, TargetConstant:i16<392>, Constant:i32<64>
t5: ch = llvm.clp.set.rspb t3,

How to constraint instructions reordering from patterns?
Krzysztof,
Thanks for your interest to my questions.
In order to clarify the context, here is the C source file of my test case.
The 3 builtins initialize some stack pointers. They have to be executed before any other instruction.
extern float fdivfaddfmul_a(float a, float b, float c, float d);
volatile static float x1,x2,x3,x4;
void _start(void)
{
float res;

How to constraint instructions reordering from patterns?
The DAG dumping will try to print some of the nodes "inline" (i.e. where
they are used) to make the output more readable, so the dump of the DAG
may not strictly reflect the node ordering.

[PATCH] D70246: [InstCombine] remove identity shuffle simplification for mask with undefs
Sanjay,
I'm looking at some missed optimizations caused by D70246. Here's a test case:
define <4 x float> @f(i32 %t32, <4 x float>* %t24) {
.entry:
%t43 = insertelement <3 x i32> undef, i32 %t32, i32 2
%t44 = bitcast <3 x i32> %t43 to <3 x float>
%t45 = shufflevector <3 x float> %t44, <3 x float> undef, <4 x i32>
<i32 0, i32 undef,

Instruction selection problems due to SelectionDAGBuilder
Hello.
I'm having problems at instruction selection with my back end with the following
basic-block due to a vector add with immediate constant vector (obtained by vectorizing a
simple C program doing vector sum map):
vector.ph: ; preds = %vector.memcheck50
%.splatinsert = insertelement <8 x i64> undef, i64 %i.07.unr, i32 0

How to constraint instructions reordering from patterns?
Hi,
Is there a kind of scope mechanism in the instruction lowering pattern language in order to control where instructions are inserted or how they are later reordered during the SelectionDiag linearization?
I know the glue chain that stick instructions together. But such mechanism in not provided in instruction lowering pattern.
I'm facing many situations where some patterns are lowered into

[SelectionDAG] Assertion due to MachineMemOperand flags difference.
Hello,
I've hit an assertion in SelectionDAG where we try to merge 2 loads
that have the same operands but their MMO flags differ. One is
dereferenceable and one is not. I'm not sure what the underlying issue
here is:
1) MDSDNode with the same operands should have the same flags set on
their respective MMO. The fact the flags differ when the
opcode,types,operands and address-space are

Filtering on a dataframe- newbie question
Hi,
newbie question. I have a data-frame with 3 named columns: Name, Obs1, Obs2.
The Name column members are made of alphanumeric characters: T1, T2, T3 etc.
I would like to acess only that subset of the data-frame with Name == T44.
X <- dataframe[dataframe$Name=='T44'] does not work.
Any ideas on how to do this?
I'm sure I'm missing a simple concept here.
Thanks,
Anjan

mystery "158"
Well, ?factor does not say anything about this behaviour (assigning numeric code instead of level of factor). And actually if you do assignment for whole vector the result is different (vector in data frame is changed to factor).

> head(temp2,2)

replace a few strings in a text file
Dear all,
I wrote a wrapper to a FORTRAN program using R. The main program uses
a text file (~200 lines) as an input describing the simulation to be
run. I typically generate the file once with the right parameters
using a combination of file(), paste(), cat(). This is fine, and it
works well, however I then need to update only a few values in the
file many times (~200 times,
