[ARM] Register pressure with -mthumb forces register reload before each call
Hi,
Compiling attached test-case, which is reduced version of of
uECC_shared_secret from tinycrypt library [1], with
--target=arm-linux-gnueabi -march=armv6-m -Oz -S
results in reloading of register holding function's address before
every call to blx:
ldr r3, .LCPI0_0
blx r3
mov r0, r6
mov r1, r5
mov r2, r4
ldr r3,

[ARM] Register pressure with -mthumb forces register reload before each call
Hi,
I have attached WIP patch for adding foldMemoryOperand to Thumb1InstrInfo.
For the following case:
void f(int x, int y, int z)
{
void bar(int, int, int);
bar(x, y, z);
bar(x, z, y);
bar(y, x, z);
bar(y, y, x);
}
it calls foldMemoryOperand twice, and thus converts two calls from blx to bl.
callMI->dump() shows the function name "bar" correctly, however in
generated

Wide to long form conversion
I have some data 'myData' in wide form (attached at the end), and
would like to convert it to long form. I wish to have five variables
in the result:
1) Subj: factor
2) Group: between-subjects factor (2 levels: s / w)
3) Reference: within-subject factor (2 levels: Me / She)
4) F: within-subject factor (2 levels: F1 / F2)
5) J: within-subject factor (2 levels: J1 / J2)
As this is the

[ARM] Register pressure with -mthumb forces register reload before each call
If I'm understanding what's going on in this test correctly, what's happening is:
* ARMTargetLowering::LowerCall prefers indirect calls when a function is called at least 3 times in minsize
* In thumb 1 (without -fno-omit-frame-pointer) we have effectively only 3 callee-saved registers (r4-r6)
* The function has three arguments, so those three plus the register we need to hold the

how to delete some columns from a matrix based on some other indicator variable
Hello,
I am not very familiar with R and need help in deleting a few columns in a
matrix.
Suppose I have a indicator variable called r and it's defined as r = (0, 0,
1, 1). A matrix D is a 3X4 matrix. If I want a new matrix which contains
only the columns of D corresponding to the elements of r that equal to 1.
how can i write a loop which creat a new matrix that contains only the last
