I'm not really okay with it; the current behavior feels unprincipled.
We have a visibility attribute which can be used to control this: On ELF
systems, "default" visibililty allows interposition (unlike on Darwin) --
that is, it explicitly ALLOWS for replacing the symbol's definition. The
policy of "You can't replace the definition of the sym...

That's rather a hack, given that the 'l' actually has semantic
meaning, but I suppose I could live

[LLVMdev] Is ConstantFoldConstantExpression meant to be idempotent?
I noticed a change in LLVM's behavior between 3.2 and 3.3/ToT, but I'm not
sure if it qualifies as a bug/regression or not.
The change is that in 3.3 and tip of trunk, calling
ConstantFoldConstantExpression on
i64 and (i64 add (i64 add (i64 ptrtoint (i64* getelementptr (i64* null,
i32 1) to i64), i64 ptrtoint (i64* getelementptr (i64* null, i32 1) to
i64)), i64 15), i64 -16)

What does RTLinux on an R-class CPU present itself as? My guess would
be "armv7l" too. I'm not too concerned about deciding that we only
care about A-class Linux, but I am concerned about taking an
unprincipled approach to the l/b suffix.
Not enough that I can't live with it though. As you say this whole
area's enough of a mess already, one more bit isn't going to break the
world.
Cheers.
Tim.

Using functions/loops for repetitive commands
I still need to do some repetitive statistical analysis on some outcomes
from a dataset.
Take the following as an example;
id sex hiv age famsize bmi resprate
1 M Pos 23 2 16 15
2 F Neg 24 5 18 14
3 F Pos 56 14 23 24
4 F Pos 67 3 33 31
5 M Neg 34 2 21 23
I want to know if there are statistically detectable differences in all of
the continuous variables in
