[LLVMdev] Link error building llc
With the TableGen problem circumvented the build proceeds quite well up

Obtaining the value of x at a given value of y in a smooth.spline object
I have some data fit to a smooth.spline object as follows: (x=vector of data
for the predictor variable, y=vector of data for the response variable)
fit <- smooth.spline(x,y)
Now, given a spline fit point y_new, I want to be able to find out what
value of x_new yielded this fit value. How to do so?
(This problem is the inverse of the predict.smooth.spline function, which
takes x_new as input

split-apply question
Hi,
I have a data frame that looks like this:
>x
x1 x2 x3
A 1 1.5
B 2 0.9
B 3 2.7
C 7 1.8
D 7 1.3
I want to "group" by the x1 column and in the case of multiple x$x1 values
(e.g., "B")d, return rows that have the smallest values of x2. In the case
of rows with only one value of x1 (e.g., "A"), return the row as is. How can
I do that?

Converting a character string into a data frame name and performing assignments to that data frame
Hi,
I would like to do the following operations:
variable.df is a character string that contains the name of the data
frame that I want to do the following operations on:
variable.df <- data.frame();
# I can do the above command using
assign( variable.df, data.frame() )
How can I perform the assignment statements below ?

[LLVMdev] New Register allocation algorithm
Hi,
I wanted to write a new register allocation algorithm. I wrote it the same
way RegAllocFast has been written and registered it. I added it to
ForceCodegenLinking struct as well. But after build, it is not listed in
llc --help. I tried to change the registered name of greedy algorithm to
something else and that doesnt seem to be reflecting in llc help either.

tapply with multiple arguments that are not part of the same data frame
Hi all,
I would like to invoke a function that takes multiple arguments (some of
which are specified columns in the data frame, and others that are
independent of the data frame) on split parts of a data frame, how do I do
this?
For example, let's say I have a data frame

[LLVMdev] undefined references in llvm

I am building customized tools for ARM using a crosscomplier. I am

help from llvm-config to the libraries I get this error:

[LLVMdev] RegAllocFast uses too much stack
I discovered recently that RegAllocFast spills all the registers before
every function call. This is the root cause of one of our recursive

-O0 and -O2, or 120 bytes at llc -O2) taking 960 bytes of stack when built

Tried it, and it seems to break quite a big chunk of our tests on SPU :)
Before r103488 ("Mostly rewrite RegAllocFast") there was no problem.
But with r103488, I get a:
